Configuration

Step 1: Create a Configuration File

Create a mockingbird.config.json file in your project root:

{
  "databases": {
    "main": {
      "type": "mysql",
      "connection": {
        "host": "${HOST}",
        "user": "${USER}",
        "password": "${PASSWORD}",
        "database": "${DATABASE}",
        "port": "${PORT}"
      }
    },
    "reporting": {
      "type": "postgres",
      "connection": {
        "host": "${REPORTING_PG_HOST}",
        "user": "${REPORTING_PG_USER}",
        "password": "${REPORTING_PG_PASSWORD}",
        "database": "${REPORTING_PG_DATABASE}",
        "port": "${REPORTING_PG_PORT}"
      }
    }
  },
  "testPatterns": [
    "tests/**/*.test.js"
  ],
  "reportConfig": {
    "type": "file",
    "outputPath": "./test-reports/report.json"
  }
}

Step 2: Create an Environment File

Create a .env file in your project root with the necessary environment variables:

HOST=your_host
PORT=your_port
USER=your_username
PASSWORD=your_password
DATABASE=your_database_name

REPORTING_PG_HOST=your_reporting_host
REPORTING_PG_PORT=your_reporting_port
REPORTING_PG_USER=your_reporting_username
REPORTING_PG_PASSWORD=your_reporting_password
REPORTING_PG_DATABASE=your_reporting_database_name

Usage

Example Test File

Create a test file (e.g., tests/db.test.js):

const { mockingbirdSDK } = require('mockingbird-sdk');

// Set the default database
mockingbirdSDK.setDefaultDatabase('main');

mockingbirdSDK
  .test('Count distinct issues for specific board in date range')
  .query(\`
    SELECT 
      COUNT(DISTINCT i.id) AS issue_count
    FROM 
      issues i
      JOIN board_issues bi ON i.id = bi.issue_id
      JOIN boards b ON bi.board_id = b.id
    WHERE
      i.created_date BETWEEN FROM_UNIXTIME(?) AND FROM_UNIXTIME(?)
      AND b.id = ?
  \`, 1721070312, 1736967912, 'github:GithubRepo:1:290006')
  .expectRowCount(1);

// Run all tests
mockingbirdSDK.run();

Running Tests

Run your tests using the Mockingbird CLI:

npx mockingbird

Example Test Cases

1. Simple Count Query

mockingbirdSDK
  .test('Count total users')
  .query('SELECT COUNT(*) AS user_count FROM users')
  .expect('user_count', 100)
  .expectRowCount(1);

2. Data Integrity Check

mockingbirdSDK
  .test('Ensure no duplicate email addresses')
  .query('SELECT email, COUNT(*) AS count FROM users GROUP BY email HAVING COUNT(*) > 1')
  .expectRowCount(0);

3. Join Query with Multiple Expectations

mockingbirdSDK
  .test('Validate order details for a specific user')
  .query(\`
    SELECT u.username, o.order_id, o.total_amount
    FROM users u
    JOIN orders o ON u.id = o.user_id
    WHERE u.username = ?
  \`, 'john_doe')
  .expect('username', 'john_doe')
  .expect('total_amount', 99.99)
  .expectRowCount(1);

4. Date Range Query

mockingbirdSDK
  .test('Check orders within a date range')
  .query(\`
    SELECT COUNT(*) AS order_count
    FROM orders
    WHERE order_date BETWEEN ? AND ?
  \`, '2023-01-01', '2023-12-31')
  .expect('order_count', 500);

5. Complex Aggregation

mockingbirdSDK
  .test('Analyze user activity')
  .query(\`
    SELECT 
      u.user_type,
      AVG(a.login_count) AS avg_logins,
      MAX(a.last_active_date) AS latest_activity
    FROM users u
    JOIN user_activity a ON u.id = a.user_id
    GROUP BY u.user_type
  \`)
  .expectRowCount(3)
  .expect('avg_logins', (value) => value > 0);
