Name: test-doubles-mocking
Author: dev-toolings

test-doubles-mocking is agent-read markdown (skill) from dev-toolings/superpowers-symfony: Create test doubles with PHPUnit mocks for isolated unit testing in Symfony.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Test Doubles Mocking (Symfony)

## Use when
- Building regression-safe behavior with TDD/functional/e2e tests.
- Converting bug reports into executable failing tests.

## Default workflow
1. Write failing test for target behavior and one boundary case.
2. Implement minimal code to pass.
3. Refactor while preserving green suite.
4. 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.

## References
- `reference.md`
- `docs/complexity-tiers.md`
