Test Doubles Mocking (Symfony)
Use when
- Building regression-safe behavior with TDD/functional/e2e tests.
- Converting bug reports into executable failing tests.
Default workflow
- Write failing test for target behavior and one boundary case.
- Implement minimal code to pass.
- Refactor while preserving green suite.
- Broaden coverage for invalid/unauthorized/not-found paths.
Guardrails
- Prefer deterministic fixtures/builders.
- Assert observable behavior, not internal implementation.
- Keep tests isolated and stable in CI.
Progressive disclosure
- Use this file for execution posture and risk controls.
- Open references when deep implementation details are needed.
Output contract
- RED/GREEN/REFACTOR trace.
- Test files changed and executed commands.
- Coverage and confidence notes.
