Reset Development Database

This skill automates the process of resetting the development MySQL database using the test scenario SQL dump.

What this skill does

1. •

   Copies the SQL dump file: Takes the test scenario dump from src/Tests/TestData/Dumps/memowikis-test-scenario_tiny.sql and copies it to src/Docker/Dev/mysql-init/schema.sql

2. •

   Replaces the database name: Changes all occurrences of memoWikisTest to memoWikis_dev in the schema file

3. •

   Reinitializes the MySQL container: Stops the Docker containers, removes the MySQL data directory, and restarts the containers

Step-by-step procedure

Step 1: Copy and transform the SQL file

Read the source SQL file and replace the database name:

# Read the SQL dump file
$sqlContent = Get-Content -Path "src/Tests/TestData/Dumps/memowikis-test-scenario_tiny.sql" -Raw

# Replace database name from memoWikisTest to memoWikis_dev
$sqlContent = $sqlContent -replace 'memoWikisTest', 'memoWikis_dev'

# Write to the Docker init directory
$sqlContent | Set-Content -Path "src/Docker/Dev/mysql-init/schema.sql" -Encoding UTF8

Step 2: Reinitialize the MySQL container

Run the following PowerShell commands from the workspace root:

cd ./src/Docker/Dev; `
docker-compose down; `
Remove-Item -Recurse -Force C:\mysql-data\development; `
docker-compose up -d

Important notes

• •The MySQL data directory C:\mysql-data\development will be completely deleted
• •The MySQL container will automatically execute schema.sql during initialization
• •The database name in the SQL file must match the MYSQL_DATABASE value in the .env file (default: memoWikis_dev)

When to use this skill

• •When you need to reset the development database to a clean state
• •After running the test ScenarioBuilderTests.Deterministic_Tiny_Scenario() to update the schema
• •When the database schema has been updated and you need to apply changes
• •When the development database is corrupted or in an inconsistent state
