## Introduction

We show how to use a database for testing.

## Run postgresql container
    
```bash
docker run --rm --name postgres \
  -e POSTGRES_USER=postgres \
  -e POSTGRES_PASSWORD=postgres \
  -e POSTGRES_DB=tfgrid-graphql \
  -p 5432:5432 -d postgres
```

## Create the DB
you can either Generate a db with relevant schema to test things locally quickly, or load a previously taken DB dump file:

### Method 1: Generate a db with relevant schema using the db helper tool:

```bash
cd tools/db/ && go run . \
  --postgres-host 127.0.0.1 \
  --postgres-db tfgrid-graphql \
  --postgres-password postgres \
  --postgres-user postgres \
  --reset \
```

### Method 2: Fill the DB from a Production db dump file, for example if you have `dump.sql` file, you can run: 

```bash
psql -h 127.0.0.1 -U postgres -d tfgrid-graphql  < dump.sql
```
