Testing
Write unit tests, integration tests, and E2E tests with Jest, Playwright, and pytest.
How it works
Generates comprehensive test suites: unit tests with proper mocking, integration tests with test databases, E2E tests with Playwright/Cypress, and property-based testing. Handles test data factories, fixture management, and CI-optimized test parallelization.
Example prompts
“Add unit and integration tests to my Express API”
“Build E2E tests with Playwright for my checkout flow”
“Create test data factories for my complex domain models”
Real-world example
A team with zero tests added comprehensive coverage: unit tests for business logic with factories, integration tests against a test database, and Playwright E2E for critical flows — catching 23 bugs before they reached production in the first month.
