  • Boundary values (min, max)
  • Single item vs multiple items
Error Cases

  • Missing required parameters
  • Type errors
  • Exception handling

3. Mocking

  • Mock external dependencies
  • Mock database calls
  • Mock API calls
  • Mock time/dates if needed

4. Test Data

  • Use factories/fixtures for test data
  • Avoid hardcoded magic values
  • Make test data realistic

5. Assertions

  • One primary assertion per test
  • Descriptive assertion messages
  • Check both positive and negative cases

Output Format

Provide:

  1. Complete test file
  2. Any helper files needed (mocks, fixtures)
