+# Buildah Module Tests
+
+This document describes the test scripts for the Buildah module in the SAL library. These tests verify the functionality of the Buildah module's container and image operations.
+
+## Test Structure
+
+The tests are organized into three main scripts:
+
+1. **Builder Pattern** (`01_builder_pattern.rhai`): Tests for the Builder pattern, including creating containers, running commands, and working with container content.
+2. **Image Operations** (`02_image_operations.rhai`): Tests for image-related operations like pulling, tagging, listing, and removing images.
+3. **Container Operations** (`03_container_operations.rhai`): Tests for container-related operations like configuration, isolation, and content management.
+
+Additionally, there's a runner script (`run_all_tests.rhai`) that executes all tests and reports results. The runner script contains simplified versions of the individual tests to avoid dependency issues.
+
+## Running the Tests
+
+To run all tests, execute the following command from the project root:
+
+```bash
+herodo --path src/rhai_tests/buildah/run_all_tests.rhai
+```
+
+To run individual test scripts:
+
+```bash
+herodo --path src/rhai_tests/buildah/01_builder_pattern.rhai
+```
+
+## Test Details
+
+### Builder Pattern Test
+
+The Builder Pattern test (`01_builder_pattern.rhai`) verifies the following functions:
+
+- `bah_new`: Creating a new Builder with a container from a specified image
+- Builder properties: `container_id`, `name`, `image`, `debug_mode`
+- `run`: Running commands in the container
+- `write_content`: Writing content to files in the container
+- `read_content`: Reading content from files in the container
+- `set_entrypoint`: Setting the container's entrypoint
+- `set_cmd`: Setting the container's command
+- `add`: Adding files to the container
+- `copy`: Copying files to the container
+- `commit`: Committing the container to an image
+- `remove`: Removing the container
+- `images`: Listing images
+- `image_remove`: Removing images
+
+### Image Operations Test
+
+The Image Operations test (`02_image_operations.rhai`) verifies the following functions:
+
+- `image_pull`: Pulling images from registries
+- `image_tag`: Tagging images
+- `images`: Listing images
+- `build`: Building images from Dockerfiles
+- `image_remove`: Removing images
+
+The test creates a temporary directory with a Dockerfile for testing the build functionality.
+
+### Container Operations Test
+
+The Container Operations test (`03_container_operations.rhai`) verifies the following functions:
+
+- `reset`: Resetting a Builder by removing its container
+- `config`: Configuring container properties
+- `run_with_isolation`: Running commands with isolation
+- Content operations: Creating and executing scripts in the container
+- `commit` with options: Committing a container with additional configuration
+
+## Test Runner
+
+The test runner script (`run_all_tests.rhai`) provides a framework for executing all tests and reporting results. It:
+
+1. Checks if Buildah is available before running tests
+2. Skips tests if Buildah is not available
+3. Contains simplified versions of each test
+4. Runs each test in a try/catch block to handle errors
+5. Catches and reports any errors
+6. Provides a summary of passed, failed, and skipped tests
+
+## Buildah Requirements
+
+These tests require the Buildah tool to be installed and available in the system's PATH. The tests will check for Buildah's availability and skip the tests if it's not found, rather than failing.
+
+## Adding New Tests
+
+To add a new test:
+
+1. Create a new Rhai script in the `src/rhai_tests/buildah` directory
+2. Add a new test section to the `run_all_tests.rhai` script
+3. Update this documentation to include information about the new test
+
+## Best Practices for Writing Tests
+
+When writing tests for the Buildah module:
+
+1. Always check if Buildah is available before running tests
+2. Use unique names for containers and images to avoid conflicts
+3. Clean up any containers, images, or files created during testing
+4. Use assertions to verify expected behavior
+5. Print clear messages about what's being tested
+6. Handle errors gracefully
+7. Make tests independent of each other
+8. Keep tests focused on specific functionality

+# Continuous Integration for Rhai Tests
+
+This document describes the continuous integration (CI) workflow for running Rhai tests in the SAL library.
+
+## GitHub Actions Workflow
+
+The SAL project includes a GitHub Actions workflow that automatically runs all Rhai tests whenever changes are made to relevant files. This ensures that the Rhai integration continues to work correctly as the codebase evolves.
+
+### Workflow File
+
+The workflow is defined in `.github/workflows/rhai-tests.yml`.
+
+### Trigger Events
+
+The workflow runs automatically when:
+
+1. Changes are pushed to the `main` or `master` branch that affect:
+   - Rhai test scripts (`src/rhai_tests/**`)
+   - Rhai module code (`src/rhai/**`)
+   - Git module code (`src/git/**`)
+   - OS module code (`src/os/**`)
+   - The test runner script (`run_rhai_tests.sh`)
+   - The workflow file itself (`.github/workflows/rhai-tests.yml`)
+
+2. A pull request is opened or updated that affects the same files.
+
+3. The workflow is manually triggered using the GitHub Actions interface.
+
+### Workflow Steps
+
+The workflow performs the following steps:
+
+1. **Checkout Code**: Checks out the repository code.
+2. **Set up Rust**: Installs the Rust toolchain.
+3. **Cache Dependencies**: Caches Rust dependencies to speed up builds.
+4. **Build herodo**: Builds the `herodo` binary used to run Rhai scripts.
+5. **Install Dependencies**: Installs system dependencies like Git and curl.
+6. **Run Rhai Tests**: Runs the `run_rhai_tests.sh` script to execute all Rhai tests.
+7. **Check for Failures**: Verifies that all tests passed.
+
+### Test Results
+
+The workflow will fail if any Rhai test fails. This prevents changes that break the Rhai integration from being merged.
+
+## Local Testing
+
+Before pushing changes, you can run the same tests locally using the `run_rhai_tests.sh` script:
+
+```bash
+./run_rhai_tests.sh
+```
+
+This will produce the same test results as the CI workflow, allowing you to catch and fix issues before pushing your changes.
+
+## Logs
+
+The test runner script creates a log file (`run_rhai_tests.log`) that contains the output of all tests. This log is used by the CI workflow to check for test failures.
+
+## Adding New Tests
+
+When adding new tests, make sure they are included in the appropriate module's test runner script (`run_all_tests.rhai`). The CI workflow will automatically run the new tests.
+
+## Troubleshooting
+
+If the CI workflow fails, check the GitHub Actions logs for details. Common issues include:
+
+1. **Missing Dependencies**: Ensure all required dependencies are installed.
+2. **Test Failures**: Fix any failing tests.
+3. **Build Errors**: Fix any errors in the Rust code.
+
+If you need to modify the workflow, edit the `.github/workflows/rhai-tests.yml` file.

+# Git Module Tests
+
+This document describes the test scripts for the Git module in the SAL library. These tests verify the functionality of the Git module's repository management and Git operations.
+
+## Test Structure
+
+The tests are organized into two main scripts:
+
+1. **Basic Git Operations** (`01_git_basic.rhai`): Tests basic Git functionality like creating a GitTree, listing repositories, finding repositories, and cloning repositories.
+2. **Git Repository Operations** (`02_git_operations.rhai`): Tests Git operations like pull, reset, commit, and push.
+
+Additionally, there's a runner script (`run_all_tests.rhai`) that executes all tests and reports results. The runner script contains simplified versions of the individual tests to avoid dependency issues.
+
+## Running the Tests
+
+To run all tests, execute the following command from the project root:
+
+```bash
+herodo --path src/rhai_tests/git/run_all_tests.rhai
+```
+
+To run individual test scripts:
+
+```bash
+herodo --path src/rhai_tests/git/01_git_basic.rhai
+```
+
+## Test Details
+
+### Basic Git Operations Test
+
+The basic Git operations test (`01_git_basic.rhai`) verifies the following functions:
+
+- `git_tree_new`: Creating a GitTree
+- `list`: Listing repositories in a GitTree
+- `find`: Finding repositories matching a pattern
+- `get`: Getting or cloning a repository
+- `path`: Getting the path of a repository
+- `has_changes`: Checking if a repository has changes
+
+The test creates a temporary directory, performs operations on it, and then cleans up after itself.
+
+### Git Repository Operations Test
+
+The Git repository operations test (`02_git_operations.rhai`) verifies the following functions:
+
+- `pull`: Pulling changes from a remote repository
+- `reset`: Resetting local changes
+- `commit`: Committing changes (method existence only)
+- `push`: Pushing changes to a remote repository (method existence only)
+
+Note: The test does not actually commit or push changes to avoid modifying remote repositories. It only verifies that the methods exist and can be called.
+
+## Test Runner
+
+The test runner script (`run_all_tests.rhai`) provides a framework for executing all tests and reporting results. It:
+
+1. Contains simplified versions of each test
+2. Runs each test in a try/catch block to handle errors
+3. Catches and reports any errors
+4. Provides a summary of passed and failed tests
+
+## Adding New Tests
+
+To add a new test:
+
+1. Create a new Rhai script in the `src/rhai_tests/git` directory
+2. Add a new test section to the `run_all_tests.rhai` script

+# Rhai Scripting in SAL
+
+This documentation covers the Rhai scripting integration in the SAL (System Abstraction Layer) library.
+
+## Overview
+
+SAL provides integration with the [Rhai scripting language](https://rhai.rs/), allowing you to use SAL's functionality in scripts. This enables automation of system tasks, testing, and more complex operations without having to write Rust code.
+
+## Modules
+
+SAL exposes the following modules to Rhai scripts:
+
+- [OS Module](os_module_tests.md): File system operations, downloads, and package management
+- Process Module: Process management and command execution
+- Git Module: Git repository operations
+- Text Module: Text processing utilities
+- Buildah Module: Container image building
+- Nerdctl Module: Container runtime operations
+- RFS Module: Remote file system operations
+- Redis Client Module: Redis database connection and operations
+- PostgreSQL Client Module: PostgreSQL database connection and operations
+
+## Running Rhai Scripts
+
+You can run Rhai scripts using the `herodo` binary:
+
+```bash
+herodo --path path/to/script.rhai
+```
+
+## Testing
+
+SAL includes test scripts for verifying the functionality of its Rhai integration. These tests are located in the `src/rhai_tests` directory and are organized by module.
+
+- [OS Module Tests](os_module_tests.md): Tests for file system, download, and package management operations
+- [Git Module Tests](git_module_tests.md): Tests for Git repository management and operations
+- [Process Module Tests](process_module_tests.md): Tests for command execution and process management
+- [Redis Client Module Tests](redisclient_module_tests.md): Tests for Redis connection and operations
+- [PostgreSQL Client Module Tests](postgresclient_module_tests.md): Tests for PostgreSQL connection and operations
+- [Text Module Tests](text_module_tests.md): Tests for text manipulation, normalization, replacement, and template rendering
+- [Buildah Module Tests](buildah_module_tests.md): Tests for container and image operations
+- [Nerdctl Module Tests](nerdctl_module_tests.md): Tests for container and image operations using nerdctl
+- [RFS Module Tests](rfs_module_tests.md): Tests for remote filesystem operations and filesystem layers
+- [Running Tests](running_tests.md): Instructions for running all Rhai tests
+- [CI Workflow](ci_workflow.md): Continuous integration workflow for Rhai tests
+
+## Examples
+
+For examples of how to use SAL's Rhai integration, see the `examples` directory in the project root. These examples demonstrate various features and use cases.
+
+## Writing Your Own Scripts
+
+When writing Rhai scripts that use SAL:
+
+1. Import the necessary modules (they're automatically registered)
+2. Use the functions provided by each module
+3. Handle errors appropriately
+4. Clean up resources when done
+
+Example:
+
+```rhai
+// Simple example of using the OS module
+let test_dir = "my_test_dir";
+mkdir(test_dir);
+
+if exist(test_dir) {
+    print(`Directory ${test_dir} created successfully`);
+
+    // Create a file
+    let test_file = test_dir + "/test.txt";
+    file_write(test_file, "Hello, world!");
+
+    // Read the file
+    let content = file_read(test_file);
+    print(`File content: ${content}`);
+
+    // Clean up
+    delete(test_dir);
+}
+```
+

+# Nerdctl Module Tests
+
+This document describes the test scripts for the Nerdctl module in the SAL library. These tests verify the functionality of the Nerdctl module's container and image operations.
+
+## Test Structure
+
+The tests are organized into three main scripts:
+
+1. **Container Operations** (`01_container_operations.rhai`): Tests for basic container operations like creating, running, executing commands, and removing containers.

+- `download_file`: Downloading a file from a URL
+- `chmod_exec`: Making a file executable
+
+The test downloads a small file from GitHub, verifies its content, and then cleans up.
+
+### Package Operations Test
+
+The package operations test (`03_package_operations.rhai`) verifies the following functions:
+
+- `package_platform`: Getting the current platform
+- `package_set_debug`: Setting debug mode for package operations
+- `package_is_installed`: Checking if a package is installed
+- `package_search`: Searching for packages
+- `package_list`: Listing installed packages
+
+Note: The test does not verify `package_install`, `package_remove`, `package_update`, or `package_upgrade` as these require root privileges and could modify the system state.
+
+## Test Runner
+
+The test runner script (`run_all_tests.rhai`) provides a framework for executing all tests and reporting results. It:
+
+1. Contains simplified versions of each test
+2. Runs each test in a try/catch block to handle errors
+3. Catches and reports any errors
+4. Provides a summary of passed and failed tests
+
+## Adding New Tests
+
+To add a new test:
+
+1. Create a new Rhai script in the `src/rhai_tests/os` directory
+2. Add a new test section to the `run_all_tests.rhai` script
+3. Update this documentation to include information about the new test
+
+## Best Practices for Writing Tests
+
+When writing tests for the OS module:
+
+1. Always clean up temporary files and directories
+2. Use assertions to verify expected behavior
+3. Print clear messages about what's being tested
+4. Handle errors gracefully
+5. Make tests independent of each other
+6. Avoid tests that require root privileges when possible
+7. Keep tests focused on specific functionality

+# PostgreSQL Client Module Tests
+
+The PostgreSQL client module provides functions for connecting to and interacting with PostgreSQL databases. These tests verify the functionality of the module.
+
+## PostgreSQL Client Features
+
+The PostgreSQL client module provides the following features:
+
+1. **Basic PostgreSQL Operations**: Execute queries, fetch results, etc.
+2. **Connection Management**: Automatic connection handling and reconnection
+3. **Builder Pattern for Configuration**: Flexible configuration with authentication support
+
+## Prerequisites
+
+- PostgreSQL server must be running and accessible
+- Environment variables should be set for connection details:
+  - `POSTGRES_HOST`: PostgreSQL server host (default: localhost)
+  - `POSTGRES_PORT`: PostgreSQL server port (default: 5432)
+  - `POSTGRES_USER`: PostgreSQL username (default: postgres)
+  - `POSTGRES_PASSWORD`: PostgreSQL password
+  - `POSTGRES_DB`: PostgreSQL database name (default: postgres)
+
+## Test Files
+
+### 01_postgres_connection.rhai
+
+Tests basic PostgreSQL connection and operations:
+
+- Connecting to PostgreSQL
+- Pinging the server
+- Creating a table
+- Inserting data
+- Querying data
+- Dropping a table
+- Resetting the connection
+
+### run_all_tests.rhai
+
+Runs all PostgreSQL client module tests and provides a summary of the results.
+
+## Running the Tests
+
+You can run the tests using the `herodo` command:
+
+```bash
+herodo --path src/rhai_tests/postgresclient/run_all_tests.rhai
+```
+
+Or run individual tests:
+
+```bash
+herodo --path src/rhai_tests/postgresclient/01_postgres_connection.rhai
+```
+
+## Available Functions
+
+### Connection Functions
+
+- `pg_connect()`: Connect to PostgreSQL using environment variables

+    print("Connected to PostgreSQL!");
+
+    // Create a table
+    let create_table_query = "CREATE TABLE IF NOT EXISTS test_table (id SERIAL PRIMARY KEY, name TEXT)";
+    pg_execute(create_table_query);
+
+    // Insert data
+    let insert_query = "INSERT INTO test_table (name) VALUES ('test')";
+    pg_execute(insert_query);
+
+    // Query data
+    let select_query = "SELECT * FROM test_table";

+# Redis Client Module Tests
+
+This document describes the test scripts for the Redis client module in the SAL library. These tests verify the functionality of the Redis client module's connection management and Redis operations.
+
+## Redis Client Features
+
+The Redis client module provides the following features:
+
+1. **Basic Redis Operations**: SET, GET, DEL, etc.
+2. **Hash Operations**: HSET, HGET, HGETALL, HDEL
+3. **List Operations**: RPUSH, LPUSH, LLEN, LRANGE
+4. **Connection Management**: Automatic connection handling and reconnection
+5. **Builder Pattern for Configuration**: Flexible configuration with authentication support
+
+## Test Structure
+
+The tests are organized into two main scripts:
+
+1. **Redis Connection** (`01_redis_connection.rhai`): Tests basic Redis connection and simple operations like PING, SET, GET, and DEL.
+2. **Redis Operations** (`02_redis_operations.rhai`): Tests more advanced Redis operations like hash operations (HSET, HGET, HGETALL, HDEL) and list operations (RPUSH, LLEN, LRANGE).
+
+Additionally, there's a runner script (`run_all_tests.rhai`) that executes all tests and reports results. The runner script contains simplified versions of the individual tests to avoid dependency issues.
+
+## Running the Tests
+
+To run all tests, execute the following command from the project root:
+
+```bash
+herodo --path src/rhai_tests/redisclient/run_all_tests.rhai
+```
+
+To run individual test scripts:
+
+```bash
+herodo --path src/rhai_tests/redisclient/01_redis_connection.rhai
+```
+
+## Test Details
+
+### Redis Connection Test
+
+The Redis connection test (`01_redis_connection.rhai`) verifies the following functions:
+
+- `redis_ping`: Checking if the Redis server is available
+- `redis_set`: Setting a key-value pair
+- `redis_get`: Getting a value by key
+- `redis_del`: Deleting a key
+
+The test creates a temporary key, performs operations on it, and then cleans up after itself.
+
+### Redis Operations Test
+
+The Redis operations test (`02_redis_operations.rhai`) verifies the following functions:
+
+- Hash operations:
+  - `redis_hset`: Setting a field in a hash
+  - `redis_hget`: Getting a field from a hash
+  - `redis_hgetall`: Getting all fields and values from a hash
+  - `redis_hdel`: Deleting a field from a hash
+
+- List operations:
+  - `redis_rpush`: Adding elements to a list
+  - `redis_llen`: Getting the length of a list
+  - `redis_lrange`: Getting a range of elements from a list
+
+The test creates temporary keys with a unique prefix, performs operations on them, and then cleans up after itself.
+
+## Test Runner
+
+The test runner script (`run_all_tests.rhai`) provides a framework for executing all tests and reporting results. It:
+
+1. Checks if Redis is available before running tests
+2. Skips tests if Redis is not available
+3. Contains simplified versions of each test
+4. Runs each test in a try/catch block to handle errors
+5. Catches and reports any errors
+6. Provides a summary of passed, failed, and skipped tests
+
+## Redis Server Requirements
+
+These tests require a Redis server to be running and accessible. The tests will attempt to connect to Redis using the following strategy:
+
+1. First, try to connect via Unix socket at `$HOME/hero/var/myredis.sock`
+2. If that fails, try to connect via TCP to `127.0.0.1` on the default Redis port (6379)
+
+If no Redis server is available, the tests will be skipped rather than failing.
+
+## Authentication Support
+
+The Redis client module will support authentication using the builder pattern in a future update.
+
+The backend implementation is ready, but the Rhai bindings are still in development.
+
+When implemented, the builder pattern will support the following configuration options:
+
+- Host: Set the Redis host
+- Port: Set the Redis port
+- Database: Set the Redis database number
+- Username: Set the Redis username (Redis 6.0+)
+- Password: Set the Redis password
+- TLS: Enable/disable TLS
+- Unix socket: Enable/disable Unix socket
+- Socket path: Set the Unix socket path
+- Connection timeout: Set the connection timeout in seconds
+
+## Adding New Tests
+
+To add a new test:
+
+1. Create a new Rhai script in the `src/rhai_tests/redisclient` directory
+2. Add a new test section to the `run_all_tests.rhai` script
+3. Update this documentation to include information about the new test
+
+## Best Practices for Writing Tests
+
+When writing tests for the Redis client module:
+
+1. Always check if Redis is available before running tests
+2. Use a unique prefix for test keys to avoid conflicts
+3. Clean up any keys created during testing
+4. Use assertions to verify expected behavior
+5. Print clear messages about what's being tested
+6. Handle errors gracefully
+7. Make tests independent of each other
+8. Keep tests focused on specific functionality

+# RFS Module Tests
+
+This document describes the test scripts for the RFS (Remote File System) module in the SAL library. These tests verify the functionality of the RFS module's mount operations and filesystem layer management.
+
+## Test Structure
+
+The tests are organized into two main scripts:
+
+1. **Mount Operations** (`01_mount_operations.rhai`): Tests for mounting, listing, and unmounting filesystems.
+2. **Filesystem Layer Operations** (`02_filesystem_layer_operations.rhai`): Tests for packing, unpacking, listing, and verifying filesystem layers.
+
+Additionally, there's a runner script (`run_all_tests.rhai`) that executes all tests and reports results. The runner script contains simplified versions of the individual tests to avoid dependency issues.
+
+## Running the Tests
+
+To run all tests, execute the following command from the project root:
+
+```bash
+herodo --path src/rhai_tests/rfs/run_all_tests.rhai
+```
+
+To run individual test scripts:
+
+```bash
+herodo --path src/rhai_tests/rfs/01_mount_operations.rhai
+```
+
+## Test Details
+
+### Mount Operations Test
+
+The Mount Operations test (`01_mount_operations.rhai`) verifies the following functions:
+
+- `rfs_mount`: Mounting a filesystem
+  - Tests mounting a local directory with options
+  - Verifies mount properties (ID, source, target, type)
+
+- `rfs_list_mounts`: Listing mounted filesystems
+  - Tests listing all mounts
+  - Verifies that the mounted filesystem is in the list
+
+- `rfs_get_mount_info`: Getting information about a mounted filesystem
+  - Tests getting information about a specific mount
+  - Verifies that the mount information is correct
+
+- `rfs_unmount`: Unmounting a specific filesystem
+  - Tests unmounting a specific mount
+  - Verifies that the mount is no longer available
+
+- `rfs_unmount_all`: Unmounting all filesystems
+  - Tests unmounting all mounts
+  - Verifies that no mounts remain after the operation
+
+The test also verifies that files in the mounted filesystem are accessible and have the correct content.
+
+### Filesystem Layer Operations Test
+
+The Filesystem Layer Operations test (`02_filesystem_layer_operations.rhai`) verifies the following functions:
+
+- `rfs_pack`: Packing a directory into a filesystem layer
+  - Tests packing a directory with files and subdirectories
+  - Verifies that the output file is created
+
+- `rfs_list_contents`: Listing the contents of a filesystem layer
+  - Tests listing the contents of a packed filesystem layer
+  - Verifies that the list includes all expected files
+
+- `rfs_verify`: Verifying a filesystem layer
+  - Tests verifying a packed filesystem layer
+  - Verifies that the layer is valid
+
+- `rfs_unpack`: Unpacking a filesystem layer
+  - Tests unpacking a filesystem layer to a directory
+  - Verifies that all files are unpacked correctly with the right content
+
+The test creates a directory structure with files, packs it into a filesystem layer, and then unpacks it to verify the integrity of the process.
+
+## Test Runner
+
+The test runner script (`run_all_tests.rhai`) provides a framework for executing all tests and reporting results. It:
+
+1. Checks if RFS is available before running tests
+2. Skips tests if RFS is not available
+3. Contains simplified versions of each test
+4. Runs each test in a try/catch block to handle errors
+5. Catches and reports any errors
+6. Provides a summary of passed, failed, and skipped tests
+
+## RFS Requirements

+
+## Adding New Tests
+
+To add a new test:
+
+1. Create a new Rhai script in the `src/rhai_tests/rfs` directory
+2. Add a new test section to the `run_all_tests.rhai` script
+3. Update this documentation to include information about the new test
+
+## Best Practices for Writing Tests
+
+When writing tests for the RFS module:
+
+1. Always check if RFS is available before running tests

+# Running Rhai Tests
+
+This document describes how to run the Rhai tests for the SAL library.
+
+## Test Structure
+
+The Rhai tests are organized by module in the `src/rhai_tests` directory:
+
+- `src/rhai_tests/os/`: Tests for the OS module
+- `src/rhai_tests/git/`: Tests for the Git module
+
+Each module directory contains:
+- Individual test scripts (e.g., `01_file_operations.rhai`)
+- A test runner script (`run_all_tests.rhai`) that runs all tests for that module
+
+## Running Tests
+
+### Running All Tests
+
+To run all Rhai tests across all modules, use the provided shell script:
+
+```bash
+./run_rhai_tests.sh
+```
+
+This script:
+1. Finds all test runner scripts in the `src/rhai_tests` directory
+2. Runs each test runner
+3. Reports the results for each module
+4. Provides a summary of all test results
+
+The script will exit with code 0 if all tests pass, or code 1 if any tests fail.
+
+### Running Tests for a Specific Module
+
+To run tests for a specific module, use the `herodo` command with the module's test runner:
+
+```bash
+herodo --path src/rhai_tests/os/run_all_tests.rhai
+```
+
+### Running Individual Tests
+
+To run a specific test, use the `herodo` command with the test script:
+
+```bash
+herodo --path src/rhai_tests/os/01_file_operations.rhai
+```
+
+## Test Output
+
+The test output includes:
+- Information about what's being tested
+- Success or failure messages for each test
+- A summary of test results
+
+Successful tests are indicated with a checkmark (✓), while failed tests show an error message.
+
+## Adding New Tests
+
+When adding new tests:
+
+1. Create a new test script in the appropriate module directory
+2. Update the module's test runner script to include the new test
+3. Update the module's documentation to describe the new test
+
+The `run_rhai_tests.sh` script will automatically find and run the new tests as long as they're included in a module's test runner script.
+
+## Troubleshooting
+
+If tests fail, check the following:
+
+1. Make sure the `herodo` binary is in your PATH
+2. Verify that the test scripts have the correct permissions
+3. Check for any dependencies required by the tests (e.g., `git` for Git module tests)
+4. Look for specific error messages in the test output

+# Text Module Tests
+
+This document describes the test scripts for the Text module in the SAL library. These tests verify the functionality of the Text module's text manipulation, normalization, replacement, and template rendering capabilities.
+
+## Test Structure
+
+The tests are organized into four main scripts:
+
+1. **Text Indentation** (`01_text_indentation.rhai`): Tests for the `dedent` and `prefix` functions.
+2. **Filename and Path Normalization** (`02_name_path_fix.rhai`): Tests for the `name_fix` and `path_fix` functions.
+3. **Text Replacement** (`03_text_replacer.rhai`): Tests for the `TextReplacer` class and its methods.
+4. **Template Rendering** (`04_template_builder.rhai`): Tests for the `TemplateBuilder` class and its methods.
+
+Additionally, there's a runner script (`run_all_tests.rhai`) that executes all tests and reports results. The runner script contains simplified versions of the individual tests to avoid dependency issues.
+
+## Running the Tests
+
+To run all tests, execute the following command from the project root:

+```bash
+herodo --path src/rhai_tests/text/run_all_tests.rhai
+```
+
+To run individual test scripts:
+
+```bash
+herodo --path src/rhai_tests/text/01_text_indentation.rhai
+```
+
+## Test Details
+
+### Text Indentation Test
+
+The text indentation test (`01_text_indentation.rhai`) verifies the following functions:

+  - Tests multiple replacements
+
+- `TextReplacer` with regex replacements
+  - Tests basic regex replacement
+  - Tests case-insensitive regex replacement
+
+- `TextReplacer` with file operations
+  - Tests `replace_file` (read file, apply replacements, return result)
+  - Tests `replace_file_to` (read file, apply replacements, write to new file)
+  - Tests `replace_file_in_place` (read file, apply replacements, write back to same file)

+
+Note: The `template_builder_open` function expects a file path, not a string template. The test creates template files on disk for testing.
+
+## Test Runner
+
+The test runner script (`run_all_tests.rhai`) provides a framework for executing all tests and reporting results. It:
+
+1. Contains simplified versions of each test
+2. Runs each test in a try/catch block to handle errors
+3. Catches and reports any errors

+# PostgreSQL Client Module
+
+The PostgreSQL client module provides a simple and efficient way to interact with PostgreSQL databases in Rust. It offers connection management, query execution, and a builder pattern for flexible configuration.
+
+## Features
+
+- **Connection Management**: Automatic connection handling and reconnection
+- **Query Execution**: Simple API for executing queries and fetching results
+- **Builder Pattern**: Flexible configuration with authentication support
+- **Environment Variable Support**: Easy configuration through environment variables
+- **Thread Safety**: Safe to use in multi-threaded applications
+
+## Usage
+
+### Basic Usage
+
+```rust
+use sal::postgresclient::{execute, query, query_one};
+
+// Execute a query
+let create_table_query = "CREATE TABLE IF NOT EXISTS users (id SERIAL PRIMARY KEY, name TEXT)";
+execute(create_table_query, &[]).expect("Failed to create table");
+
+// Insert data
+let insert_query = "INSERT INTO users (name) VALUES ($1) RETURNING id";
+let rows = query(insert_query, &[&"John Doe"]).expect("Failed to insert data");
+let id: i32 = rows[0].get(0);
+
+// Query data
+let select_query = "SELECT id, name FROM users WHERE id = $1";
+let row = query_one(select_query, &[&id]).expect("Failed to query data");
+let name: String = row.get(1);
+println!("User: {} (ID: {})", name, id);
+```
+
+### Connection Management
+
+The module manages connections automatically, but you can also reset the connection if needed:
+
+```rust
+use sal::postgresclient::reset;
+
+// Reset the PostgreSQL client connection
+reset().expect("Failed to reset connection");
+```
+
+### Builder Pattern
+
+The module provides a builder pattern for flexible configuration:
+
+```rust
+use sal::postgresclient::{PostgresConfigBuilder, with_config};
+
+// Create a configuration builder
+let config = PostgresConfigBuilder::new()
+    .host("db.example.com")
+    .port(5432)
+    .user("postgres")
+    .password("secret")
+    .database("mydb")
+    .application_name("my-app")
+    .connect_timeout(30)
+    .ssl_mode("require");
+
+// Connect with the configuration
+let client = with_config(config).expect("Failed to connect");
+```
+
+## Configuration
+
+### Environment Variables
+
+The module uses the following environment variables for configuration:
+
+- `POSTGRES_HOST`: PostgreSQL server host (default: localhost)
+- `POSTGRES_PORT`: PostgreSQL server port (default: 5432)
+- `POSTGRES_USER`: PostgreSQL username (default: postgres)
+- `POSTGRES_PASSWORD`: PostgreSQL password
+- `POSTGRES_DB`: PostgreSQL database name (default: postgres)
+
+### Connection String
+
+The connection string is built from the configuration options:
+
+```
+host=localhost port=5432 user=postgres dbname=postgres
+```
+
+With authentication:
+
+```
+host=localhost port=5432 user=postgres password=secret dbname=postgres
+```
+
+With additional options:
+
+```
+host=localhost port=5432 user=postgres dbname=postgres application_name=my-app connect_timeout=30 sslmode=require
+```
+
+## API Reference
+
+### Connection Functions
+
+- `get_postgres_client() -> Result<Arc<PostgresClientWrapper>, PostgresError>`: Get the PostgreSQL client instance
+- `reset() -> Result<(), PostgresError>`: Reset the PostgreSQL client connection
+
+### Query Functions
+
+- `execute(query: &str, params: &[&(dyn postgres::types::ToSql + Sync)]) -> Result<u64, PostgresError>`: Execute a query and return the number of affected rows
+- `query(query: &str, params: &[&(dyn postgres::types::ToSql + Sync)]) -> Result<Vec<Row>, PostgresError>`: Execute a query and return the results as a vector of rows
+- `query_one(query: &str, params: &[&(dyn postgres::types::ToSql + Sync)]) -> Result<Row, PostgresError>`: Execute a query and return a single row
+- `query_opt(query: &str, params: &[&(dyn postgres::types::ToSql + Sync)]) -> Result<Option<Row>, PostgresError>`: Execute a query and return an optional row
+
+### Configuration Functions
+
+- `PostgresConfigBuilder::new() -> PostgresConfigBuilder`: Create a new PostgreSQL configuration builder
+- `with_config(config: PostgresConfigBuilder) -> Result<Client, PostgresError>`: Create a new PostgreSQL client with custom configuration
+
+## Error Handling
+
+The module uses the `postgres::Error` type for error handling:
+
+```rust
+use sal::postgresclient::{query, query_one};
+
+// Handle errors
+match query("SELECT * FROM users", &[]) {
+    Ok(rows) => {
+        println!("Found {} users", rows.len());
+    },
+    Err(e) => {
+        eprintln!("Error querying users: {}", e);
+    }
+}
+
+// Using query_one with no results
+match query_one("SELECT * FROM users WHERE id = $1", &[&999]) {
+    Ok(_) => {
+        println!("User found");
+    },
+    Err(e) => {
+        eprintln!("User not found: {}", e);
+    }
+}
+```
+
+## Thread Safety
+
+The PostgreSQL client module is designed to be thread-safe. It uses `Arc` and `Mutex` to ensure safe concurrent access to the client instance.
+
+## Examples
+
+### Basic CRUD Operations
+
+```rust
+use sal::postgresclient::{execute, query, query_one};
+
+// Create
+let create_query = "INSERT INTO users (name, email) VALUES ($1, $2) RETURNING id";
+let rows = query(create_query, &[&"Alice", &"alice@example.com"]).expect("Failed to create user");
+let id: i32 = rows[0].get(0);
+
+// Read
+let read_query = "SELECT id, name, email FROM users WHERE id = $1";
+let row = query_one(read_query, &[&id]).expect("Failed to read user");
+let name: String = row.get(1);
+let email: String = row.get(2);
+
+// Update
+let update_query = "UPDATE users SET email = $1 WHERE id = $2";
+let affected = execute(update_query, &[&"new.alice@example.com", &id]).expect("Failed to update user");
+
+// Delete
+let delete_query = "DELETE FROM users WHERE id = $1";
+let affected = execute(delete_query, &[&id]).expect("Failed to delete user");
+```
+
+### Transactions
+
+Transactions are not directly supported by the module, but you can use the PostgreSQL client to implement them:
+
+```rust
+use sal::postgresclient::{execute, query};
+
+// Start a transaction
+execute("BEGIN", &[]).expect("Failed to start transaction");
+
+// Perform operations
+let insert_query = "INSERT INTO accounts (user_id, balance) VALUES ($1, $2)";
+execute(insert_query, &[&1, &1000.0]).expect("Failed to insert account");
+
+let update_query = "UPDATE users SET has_account = TRUE WHERE id = $1";
+execute(update_query, &[&1]).expect("Failed to update user");
+
+// Commit the transaction
+execute("COMMIT", &[]).expect("Failed to commit transaction");
+
+// Or rollback in case of an error
+// execute("ROLLBACK", &[]).expect("Failed to rollback transaction");
+```
+
+## Testing
+
+The module includes comprehensive tests for both unit and integration testing:
+
+```rust
+// Unit tests
+#[test]
+fn test_postgres_config_builder() {
+    let config = PostgresConfigBuilder::new()
+        .host("test-host")
+        .port(5433)
+        .user("test-user");
+    
+    let conn_string = config.build_connection_string();
+    assert!(conn_string.contains("host=test-host"));
+    assert!(conn_string.contains("port=5433"));
+    assert!(conn_string.contains("user=test-user"));
+}
+
+// Integration tests
+#[test]
+fn test_basic_postgres_operations() {
+    // Skip if PostgreSQL is not available
+    if !is_postgres_available() {
+        return;
+    }
+    
+    // Create a test table
+    let create_table_query = "CREATE TEMPORARY TABLE test_table (id SERIAL PRIMARY KEY, name TEXT)";
+    execute(create_table_query, &[]).expect("Failed to create table");
+    
+    // Insert data
+    let insert_query = "INSERT INTO test_table (name) VALUES ($1) RETURNING id";
+    let rows = query(insert_query, &[&"test"]).expect("Failed to insert data");
+    let id: i32 = rows[0].get(0);
+    
+    // Query data
+    let select_query = "SELECT name FROM test_table WHERE id = $1";
+    let row = query_one(select_query, &[&id]).expect("Failed to query data");
+    let name: String = row.get(0);
+    assert_eq!(name, "test");
+}
+```

 - **Database Selection**: Uses the `REDISDB` environment variable to select the Redis database (defaults to 0)
+- **Authentication Support**: Supports username/password authentication
+- **Builder Pattern**: Flexible configuration with a builder pattern
+- **TLS Support**: Optional TLS encryption for secure connections
 - **Error Handling**: Comprehensive error handling with detailed error messages
 - **Thread Safety**: Safe to use in multi-threaded applications

+### Builder Pattern
+
+The module provides a builder pattern for flexible configuration:
+
+```rust
+use crate::redisclient::{RedisConfigBuilder, with_config};
+
+// Create a configuration builder
+let config = RedisConfigBuilder::new()
+    .host("redis.example.com")
+    .port(6379)
+    .db(1)
+    .username("user")
+    .password("secret")
+    .use_tls(true)
+    .connection_timeout(30);
+
+// Connect with the configuration
+let client = with_config(config)?;
+```
+
+### Unix Socket Connection
+
+You can explicitly configure a Unix socket connection:
+
+```rust
+use crate::redisclient::{RedisConfigBuilder, with_config};
+
+// Create a configuration builder for Unix socket
+let config = RedisConfigBuilder::new()
+    .use_unix_socket(true)
+    .socket_path("/path/to/redis.sock")
+    .db(1);
+
+// Connect with the configuration
+let client = with_config(config)?;
+```
+
 ## Environment Variables
 
 - `REDISDB`: Specifies the Redis database number to use (default: 0)
+- `REDIS_HOST`: Specifies the Redis host (default: 127.0.0.1)
+- `REDIS_PORT`: Specifies the Redis port (default: 6379)
+- `REDIS_USERNAME`: Specifies the Redis username for authentication
+- `REDIS_PASSWORD`: Specifies the Redis password for authentication
 - `HOME`: Used to determine the path to the Redis Unix socket
 
 ## Connection Strategy
@@ -77,6 +122,25 @@ The module includes both unit tests and integration tests:
 - Integration tests that require a real Redis server
 - Tests automatically skip if Redis is not available
 
+### Unit Tests
+
+- Tests for the builder pattern and configuration
+- Tests for connection URL building
+- Tests for environment variable handling
+
+### Integration Tests
+
+- Tests for basic Redis operations (SET, GET, EXPIRE)
+- Tests for hash operations (HSET, HGET, HGETALL, HDEL)
+- Tests for list operations (RPUSH, LLEN, LRANGE, LPOP)
+- Tests for error handling (invalid commands, wrong data types)
+
+Run the tests with:

 ## Thread Safety
 
 The Redis client is wrapped in an `Arc<Mutex<>>` to ensure thread safety when accessing the global instance.
