- ·Captures expected behavior and edge cases before implementation
- ·Uses framework-appropriate test structure (Jest/pytest/JUnit/Go/RSpec)
- ·Follows Arrange-Act-Assert pattern with isolated fixtures
- ·Employs shouldXwhenY naming convention
Use Cases

Generate failing tests for the TDD red phase to define expected behavior and edge cases.

date_added:2026-02-27
Write comprehensive failing tests following TDD red phase principles.
[Extended thinking: Generates failing tests that properly define expected behavior using test-automator agent.]
Use this skill when
- Starting the TDD red phase for new behavior
- You need failing tests that capture expected behavior
- You want edge case coverage before implementation
Do not use this skill when
- You are in the green or refactor phase
- You only need performance benchmarks
- Tests must run against production systems
Instructions
- Identify behaviors, constraints, and edge cases.
- Generate failing tests that define expected outcomes.
- Ensure failures are due to missing behavior, not setup errors.
- Document how to run tests and verify failures.
Safety
- Keep test data isolated and avoid production environments.
- Avoid flaky external dependencies in the red phase.
Role
Generate failing tests using Task tool with subagent_type="unit-testing::test-automator".
