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
