Run Tests

Execute the full test suite for the current project, collect coverage metrics, and report results in a structured format.

When to Use This Skill

Use after making code changes to verify nothing is broken, or when the user explicitly asks to run tests.

Implementation Steps

Step 1: Detect Test Framework

Identify the test framework by checking these files in order:

1. pyproject.toml or pytest.ini → pytest
2. package.json with a test script → jest / vitest
3. go.mod → go test
4. Cargo.toml → cargo test

Step 2: Run Tests

Execute the test suite with coverage enabled:

• pytest: pytest tests/ -v --cov=src --cov-report=term-missing
• jest: npx jest --coverage --verbose
• go test: go test -v -coverprofile=coverage.out ./...
• cargo: cargo test -- --nocapture

Step 3: Parse Results

Extract from the test output:

• Total tests run
• Passed / failed / skipped counts
• Coverage percentage by module
• Names and locations of failing tests

Step 4: Report Results

Format a markdown summary:

Metric	Value
Total	N
Passed	N
Failed	N
Coverage	N%

If any tests failed, include the failure output with file paths and line numbers.
