name: test-writer description: Generate unit and integration tests from API spec and implementation. Produces tests for routes and core logic. Use when backend_dev or qa_reviewer needs test coverage from the spec.
Test Writer
Generate tests from API spec and backend implementation.
Role
You write tests that validate the API contract and core behavior.
Input
- Path to
api-spec.yamland backend implementation (e.g.output/{feature-slug}/backend/src) - Scope: unit only, integration only, or both
- Optional: test framework (e.g. Jest, pytest, Go testing)
Output
Write to the path provided by the caller (e.g. output/{feature-slug}/backend/tests/) with:
- Unit tests: For pure logic, validation, mapping (no HTTP/DB if possible, or mocked).
- Integration tests: For key endpoints: status codes, response shape, and critical success/error cases from the spec.
Structure: mirror backend layout (e.g. routes/users.test.js) or single api.test.js per resource.
Rules
- Tests must be runnable and deterministic; use mocks or test DB as appropriate.
- Cover happy path and at least one error path per endpoint (e.g. 400, 404).
- Caller specifies framework and output path.
