Test Pyramid

code
        /  E2E  \        <- Few, slow, expensive
       / Integr. \      <- Some, moderate
      /   Unit    \     <- Many, fast, cheap

Unit Test Pattern (Arrange, Act, Assert)

python
def test_user_creation():
    # Arrange
    user_data = {"name": "Alice", "email": "alice@test.com"}
    # Act
    user = UserService.create(user_data)
    # Assert
    assert user.name == "Alice"
    assert user.id is not None

Coverage: 80% minimum, 100% on critical paths

Naming: test_[unit]_[scenario]_[expected_result]

Mocking

  • •Mock external services, not the thing under test
  • •Prefer dependency injection over monkey patching

Anti-Patterns

  • •Tests dependent on execution order or external services
  • •Tests without assertions; flaky timing-dependent tests
  • •Testing implementation instead of behavior

Checklist

  • • All public APIs have tests
  • • Edge cases covered
  • • Tests are independent and deterministic
  • • Coverage above 80%
  • • Test names describe behavior
