This improves reliability and reduces the chance of using outdated images. Improves the robustness of the installation process. - Added comprehensive unit tests for `PostgresInstallerConfig`, `PostgresInstallerError`, `install_postgres`, `create_database`, `execute_sql`, and `is_postgres_running` functions to ensure correctness and handle potential errors effectively. Improves code quality and reduces the risk of regressions. --- src/postgresclient/installer.rs | 14 ++ src/postgresclient/tests.rs | 229 ++++++++++++++++++++++++++++++++ 2 files changed, 243 insertions(+) diff --git a/src/postgresclient/installer.rs b/src/postgresclient/installer.rs index 862f596..c310609 100644 --- a/src/postgresclient/installer.rs +++ b/src/postgresclient/installer.rs @@ -168,6 +168,20 @@ pub fn install_postgres( // Build the image name let image = format!("postgres:{}", config.version);
