What You'll Practice

4 steps with hands-on AI practice using synthetic data.

1

Analyze code structure

Identify all functions, classes, and methods that need testing. Map inputs, outputs, and dependencies.

2

Generate edge case scenarios

List all edge cases including null/undefined, empty arrays, boundary values, invalid inputs, and error conditions.

3

Write test suite

Generate complete unit tests using your testing framework (Jest, Vitest, etc.) with mocks for dependencies.

4

Add assertions and coverage

Ensure all branches are covered with clear assertions. Add test descriptions explaining what each test validates.
