tdd-workflow
Build TypeScript Features with TDD
Teams often struggle to keep tests focused during fast TypeScript changes. This skill guides RED-GREEN-REFACTOR work with practical Node.js patterns.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "tdd-workflow" from https://skillstore.io/skills/doubleslashse-tdd-workflow.md and its manifest at https://skillstore.io/api/skills/doubleslashse-tdd-workflow/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "tdd-workflow". Help me test an email validator before implementation.
Expected outcome:
- A short behavior list for valid, invalid, empty, and formatted email inputs.
- A recommended first failing test and the expected failure reason.
- A note to refactor only after the validator behavior passes.
Using "tdd-workflow". How should I isolate a service that writes users and logs events?
Expected outcome:
- Use a fake repository for stored users and a mock logger for interaction checks.
- Keep each test independent with a fresh test context.
- Assert observable behavior before checking supporting interactions.
Using "tdd-workflow". Review my plan for refactoring after tests pass.
Expected outcome:
- A refactoring sequence that keeps the public behavior unchanged.
- A list of brittle assertions to replace with behavior-focused checks.
- A reminder to rerun the relevant unit and integration tests after each change.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Add a Feature Safely
Plan failing tests, implement the smallest behavior, and refactor after the test passes.
Standardize Team Testing
Use shared naming, AAA structure, and test organization patterns across a Node.js codebase.
Teach Practical TDD
Explain test doubles, parameterized tests, async tests, and dependency injection with concise examples.
Try These Prompts
Use the tdd-workflow skill to plan a RED-GREEN-REFACTOR cycle for [feature] in a Node.js TypeScript project.
Use the tdd-workflow skill to identify the first failing tests for [behavior], including happy path, edge cases, and error cases.
Use the tdd-workflow skill to choose suitable stubs, mocks, fakes, or spies for [module] and explain why each one fits.
Use the tdd-workflow skill to review [test plan or module behavior] and propose safe refactoring steps while preserving test coverage.
Best Practices
- Start with one observable behavior and write the failing test first.
- Keep test data builders clear and close to the domain language.
- Refactor only after the relevant test set passes.
Avoid
- Testing private state instead of user-visible behavior.
- Sharing mutable test state across unrelated cases.
- Overusing snapshots for logic that needs explicit assertions.
