Regression Test Tracker

Track critical tests and ensure new changes don't break existing functionality.

Purpose

Maintain stability by:

• Tracking critical tests - Mark tests for regression suite
• Automated execution - Run before deployments
• Change impact analysis - Which tests affected by changes
• Test history - Track pass/fail over time
• Flaky test detection - Identify unreliable tests

Usage

/track-regression                    # Run regression suite
/track-regression --mark             # Mark current test as regression
/track-regression --history          # Show test history
/reg                                 # Shortcut

Regression Suite Management

Tag tests as regression tests:

// Jest
describe('User Login', () => {
  it('[REGRESSION] should login with valid credentials', async () => {
    // Critical login test
  });
});

// pytest
@pytest.mark.regression
def test_payment_processing():
    # Critical payment test
    pass

• Keep regression suite fast (<5 min)
• Monitor for flaky tests
• Update when requirements change
