What You'll Practice
4 steps with hands-on AI practice using synthetic data.
Analyze code structure
Identify all functions, classes, and methods that need testing. Map inputs, outputs, and dependencies.
Generate edge case scenarios
List all edge cases including null/undefined, empty arrays, boundary values, invalid inputs, and error conditions.
Write test suite
Generate complete unit tests using your testing framework (Jest, Vitest, etc.) with mocks for dependencies.
Add assertions and coverage
Ensure all branches are covered with clear assertions. Add test descriptions explaining what each test validates.
