Test Quick

When to Use This Skill

Context

• Project type: !find . -maxdepth 1 \( -name 'pyproject.toml' -o -name 'package.json' -o -name 'Cargo.toml' -o -name 'go.mod' \)
• Test directories: !find . -maxdepth 2 -type d \( -path '*/tests/unit' -o -path '*/test/unit' -o -path '*/__tests__/unit' \)
• Last test run: !find . -path '*/.pytest_cache/v/cache/*' -maxdepth 4 -name 'lastfailed'

Parameters

• $1: Optional path or test pattern
• --watch: Enable watch mode for continuous feedback
• --affected: Only run tests for files changed since last commit

Your task

Delegate this task to the `test-runner` agent.

Use the Agent tool with subagent_type: test-runner to run fast unit tests only. Pass all the context gathered above and specify Tier 1 (unit tests) execution.

The test-runner agent should:

1. Run unit tests only (target < 30s):

• Exclude slow, integration, and E2E tests
• Use appropriate markers/flags for the framework:
• pytest: -m "not slow and not integration and not e2e"
• vitest: --exclude="**/e2e/**" --exclude="**/integration/**"
• cargo: --lib
• go: -short

2. Apply options:

• If --watch: Enable continuous test execution
• If --affected: Only test changed files

3. Fail fast: Stop on first failure (-x or --bail)

4. Provide concise output:

   Unit Tests: [PASS|FAIL]
   Passed: X | Failed: Y | Duration: Zs

   Failures (if any):
   - test_name: Brief error (file:line)

   Rerun failed: [command]

5. Post-action guidance:

• If all pass: Ready for continued development
• If failures: Fix before proceeding (fail fast principle)
• If > 30s: Suggest /test:consult for optimization

Provide the agent with:

• All context from the section above
• The parsed parameters
• Explicit instruction: Tier 1 only, skip slow tests

The agent has expertise in:

• Tiered test execution
• Fast feedback loops
• Test isolation and parallelization
