Test Runner

name: test-runner description: Guide for running and analyzing test results across different languages and frameworks. Use this when you need to run tests, interpret test failures, or ensure test coverage.

Test Runner Skill

This skill provides standardized ways to run tests and interpret results.

Test Commands by Language

Python

# Run all tests
python -m pytest tests/ -v

# Run specific test
python -m pytest tests/test_specific.py -v

# With coverage
python -m pytest tests/ --cov=src --cov-report=term-missing

JavaScript/TypeScript

# Run all tests
npm test

# Run specific test
npm test -- --grep "test name"

# With coverage
npm run test:coverage

Go

# Run all tests
go test ./...

# With verbose output
go test -v ./...

# With coverage
go test -cover ./...

Interpreting Results

Success Indicators

• All tests pass
• No deprecation warnings
• Coverage meets threshold

Failure Patterns

Test Assertion Failed

AssertionError: Expected X, got Y

→ Fix the code to produce expected output

Import Error

ModuleNotFoundError: No module named 'xyz'

→ Install missing dependency or fix import path

Timeout

TimeoutError: Test exceeded 30s limit

→ Optimize the code or increase timeout

Quick Actions

Fix Failing Test

1. Read the error message carefully
2. Find the relevant code
3. Fix the issue
4. Re-run just that test

Add Missing Test

1. Identify untested code
2. Create test file if needed
3. Write test following existing patterns
4. Run to verify it passes
