Testing

Setup

1. Create test database and user:

CREATE DATABASE IF NOT EXISTS mcp_test;
CREATE USER IF NOT EXISTS 'mcp_test'@'localhost' IDENTIFIED BY 'mcp_test_password';
GRANT ALL PRIVILEGES ON mcp_test.* TO 'mcp_test'@'localhost';
FLUSH PRIVILEGES;

2. Create .env.test:

MYSQL_HOST=127.0.0.1
MYSQL_PORT=3306
MYSQL_USER=mcp_test
MYSQL_PASS=mcp_test_password
MYSQL_DB=mcp_test

3. Run setup script:

pnpm run setup:test:db
