• When implementing tests for primary user workflows
• When mocking external dependencies (APIs, databases, file systems)
• When writing test cases with clear, descriptive names
• When focusing on testing behavior rather than implementation details
• When ensuring tests execute quickly (milliseconds for unit tests)
• When completing feature implementation and adding strategic tests
• When working with test frameworks (Jest, Mocha, RSpec, pytest, JUnit)
• When determining appropriate test coverage for business-critical code
• When refactoring tests to reduce brittleness or improve clarity
• When setting up test fixtures or test data
