platform-testing（平台测试）

Principles

• Test behavior, not implementation details
• Prefer integration tests over unit tests (Testing Trophy)
• Arrange-Act-Assert (AAA) pattern in every test
• Tests must be independent — no shared mutable state
• Keep tests small and focused — one behavior per test
• Name tests to describe the behavior being verified
• Optimize for confidence, not coverage percentage
• Don't chase 100% coverage — test what matters

Rules

See rules index for detailed patterns.

Examples

Positive Trigger

User: "Define integration-vs-unit test boundaries and mocking strategy."

Expected behavior: Use platform-testing guidance, follow its workflow, and return actionable output.

Non-Trigger

User: "Create a tRPC router for billing procedures."

Expected behavior: Do not prioritize platform-testing; choose a more relevant skill or proceed without it.

Troubleshooting

Skill Does Not Trigger

• Error: The skill is not selected when expected.
• Cause: Request wording does not clearly match the description trigger conditions.
• Solution: Rephrase with explicit domain/task keywords from the description and retry.

Guidance Conflicts With Another Skill

• Error: Instructions from multiple skills conflict in one task.
• Cause: Overlapping scope across loaded skills.
• Solution: State which skill is authoritative for the current step and apply that workflow first.

Output Is Too Generic

• Error: Result lacks concrete, actionable detail.
• Cause: Task input omitted context, constraints, or target format.
• Solution: Add specific constraints (environment, scope, format, success criteria) and rerun.

Workflow

1. Identify whether the request clearly matches platform-testing scope and triggers.
2. Apply the skill rules and referenced guidance to produce a concrete result.
3. Validate output quality against constraints; if gaps remain, refine once with explicit assumptions.
