To generate failing tests for the TDD red phase, define expected behavior and edge cases upfront before implementation. This approach captures invalid inputs and constraints early, creating deterministic test skeletons that guide subsequent development.

Writing failing tests before implementation specifies expected behavior for new features and edge cases. This ensures constraints are captured upfront, providing clear targets for your code to satisfy during the development process.

Document test automation steps for verifying failing tests by outlining how to run tests and verify failures in isolated environments. This ensures deterministic failing tests are validated correctly before moving to implementation.

Test generation for the red phase applies across frameworks as appropriate. It requires framework-appropriate test skeletons to define expected behavior, ensuring edge cases and invalid inputs guide implementation regardless of the specific testing framework used.

You can automate test generation for edge cases and invalid inputs to guide implementation and error handling. This specifies expected behavior for new features by illustrating constraints upfront through deterministic failing tests.
