Test Runner Skill

Director Mode Lite - Test Execution Reference

Supported Frameworks

Detect the project's test framework, then use its runner:

Language	Frameworks
JavaScript/TypeScript	Jest, Vitest, Mocha, Playwright
Python	pytest, unittest
Go	go test
Rust	cargo test
Java	JUnit, Maven, Gradle

Test Workflow

Step 1: Detect Framework

Check for configuration files:

jest.config.* → Jest
vitest.config.* → Vitest
pytest.ini or pyproject.toml → pytest
go.mod → go test
Cargo.toml → cargo test

Step 2: Run Tests

Run tests with the detected framework's command:

# JavaScript/TypeScript
npm test        # or pnpm test / yarn test

# Python
pytest -v

# Go
go test ./...

# Rust
cargo test

For coverage, add the framework's coverage flag (for example pytest --cov, jest --coverage, go test -cover ./..., cargo tarpaulin).

Step 3: Analyze Results

For each failure, capture:

Test name and file location
Expected vs Actual result
Root cause analysis
Suggested fix

Output Format

## Test Results

**Status**: 2 failed, 18 passed (90% pass rate)

### Failed Tests

#### 1. `user.test.ts` - should validate email format
- **Location**: `src/tests/user.test.ts:45`
- **Expected**: `false` for invalid email
- **Actual**: `true`
- **Root Cause**: Regex pattern missing check for domain
- **Fix**: Update regex in `validateEmail()` function

#### 2. `api.test.ts` - should return 401 for unauthorized
- **Location**: `src/tests/api.test.ts:78`
- **Expected**: Status 401
- **Actual**: Status 500
- **Root Cause**: Auth middleware throwing unhandled error
- **Fix**: Add try-catch in auth middleware

### Coverage Summary
- Statements: 85%
- Branches: 72%
- Functions: 90%
- Lines: 84%

TDD Support

When working with the /test-first command:

Red: Write a failing test first
Green: Implement the minimum code to pass
Refactor: Improve without changing behavior

Cycle: Write Test → Run (Fail) → Implement → Run (Pass) → Refactor → Run (Pass)
