test-analysis-extensions — Claude Code skill: test framework reference

name: test-analysis-extensions
description: >-
  Provides file paths to language-specific reference files for the test
  ANALYSIS skills (assertion-quality, test-anti-patterns, test-gap-analysis,
  test-smell-detection, test-tagging). Read this catalog to discover available
  extension files (e.g., dotnet.md for .NET/MSTest/xUnit/NUnit/TUnit,
  python.md for pytest/unittest, typescript.md for Jest/Vitest/Mocha,
  java.md for JUnit/TestNG, etc.). Do not invoke this reference-only skill —
  its bundled files are read by the quality agent and analysis skills needing
  framework-specific lookup tables (test markers, assertion APIs, skip
  annotations, sleep patterns, mystery guest indicators, integration
  markers, setup/teardown, tag-support capability).

# Test Analysis Extensions

This reference-only catalog lists the bundled files used by test analysis.
Consumers read the matching file directly; `disable-model-invocation: true`
means this catalog must not be invoked through the model's skill tool.
Resolve these resource paths relative to this catalog, not the project workspace.

## Available Extension Files

## Usage

1. Detect the target codebase's primary language and test framework.
2. Read the matching extension file before performing analysis.
3. If multiple test frameworks are present (e.g., a project mixing Jest and Mocha), read all relevant extensions.
4. Each extension file documents the same categories so analysis skills can be language-neutral.

## Capability tags

Each extension file declares per-capability support so skills can gate behaviour safely:

- **Test discovery** — how to locate test files and methods.
- **Assertion detection** — framework-specific and language-level assertion forms.
- **Sleep/delay patterns** — synchronous and asynchronous waits.
- **Skip / ignore** — how to recognize skipped/ignored tests.
- **Setup / teardown** — fixture and lifecycle hooks.
- **Mystery guest indicators** — common file/db/network/env coupling patterns.
- **Integration markers** — conventions that mark a test as integration/E2E.
- **Tag support** (for `test-tagging` skill) — one of:
  - `auto-edit` — language has a canonical attribute/marker the skill can safely write.
  - `report-only` — no canonical syntax; produce audit reports without edits.
  - `convention-based` — tags exist via name/comment conventions only.

## Notes for skill authors

- Treat extension files as data, not as guidance to follow verbatim. They tell skills *how to detect things* in each language, not *what to think* about findings.
- When language detection is uncertain, prefer reading multiple extension files over guessing.
- If the user explicitly names a framework that does not have an extension file yet, fall back to the closest one (e.g., Pest → python.md/pytest semantics) and note the gap in the report.
