Test it

Using "backend-testing". Write unit tests for password validation

Expected outcome:

  • Test suite with 7 test cases covering all password requirements
  • Tests for valid password, length check, uppercase, lowercase, number, special character
  • Uses AAA pattern (Arrange-Act-Assert)

Using "backend-testing". Create integration tests for user registration API

Expected outcome:

  • Tests for successful registration, duplicate email rejection, validation errors
  • Verifies database state changes after successful registration
  • Uses Supertest for HTTP requests

Security Audit

Low Risk
v1 • 3/9/2026

This is a legitimate backend testing skill. All 137 static findings are false positives - they represent documentation examples of standard testing practices (npm install commands, HTTP test requests using Supertest, test file paths, and .env.test configuration). No malicious behavior detected.

External Commands in Documentation
The skill contains 52 examples of shell commands (npm install, jest config) in code blocks. These are documentation examples, not actual code execution.
SKILL.md:231-830
Network Requests in Test Examples
The skill shows HTTP test requests using Supertest and mocked fetch calls. This is legitimate API testing behavior.
SKILL.md:60-609
Environment Variable Access
The skill references environment variables for test configuration, which is a testing best practice.

What You Can Build

Developer Writing New API Tests

A developer needs to write tests for a new Express.js REST API endpoint. The skill generates comprehensive unit and integration tests.

QA Engineer Creating Test Suite

A QA engineer needs to create a full test suite for a Python FastAPI backend with database testing.

Team Implementing TDD

A development team adopting Test-Driven Development needs guidance on writing tests before code.

Try These Prompts

Basic API Test Request 
Write unit tests for a user authentication function that validates passwords. Use Jest with TypeScript. Test cases: valid password, too short, missing uppercase, missing number.
Integration Test Request 
Create integration tests for a POST /users endpoint in Express.js using Jest and Supertest. Test: successful creation, duplicate email, missing fields. Use in-memory database.
Authentication Test Request 
Write tests for JWT authentication: login success, login with wrong password, accessing protected route without token, accessing with invalid token, admin-only route access.
Full Test Suite Request 
Set up a complete test suite for a Django REST API using Pytest. Include: test configuration, fixture setup, unit tests for serializers, integration tests for views, authentication tests, coverage configuration.

Best Practices

  • Use test isolation with beforeEach/afterEach to reset state between tests
  • Apply AAA pattern (Arrange-Act-Assert) for clear test structure
  • Mock external dependencies (APIs, databases) to ensure fast, reliable tests

Avoid

  • Do not use production database for tests - use in-memory or test database
  • Do not make real external API calls in tests - always mock them
  • Do not write tests that depend on execution order - ensure independence

Frequently Asked Questions

What testing frameworks does this skill support?
The skill supports Jest, Pytest, Mocha/Chai, JUnit, and TestClient from various frameworks like Express, Django, FastAPI, and Spring Boot.
Does this skill run the tests?
No, this skill generates test code. You need to run the tests yourself using the test framework commands.
How do I set up a test database?
Use in-memory databases like sqlite for tests, or create a separate test database. Never use production data for testing.
How do I mock external APIs?
Use framework-specific mocking: jest.mock for Jest, unittest.mock for Pytest, or libraries like nock for HTTP mocking.
What is the recommended test coverage?
Aim for 80% coverage as a minimum. Configure coverage thresholds in your test framework config file.
Can this skill help with TDD?
Yes, the skill includes guidance on Test-Driven Development and can generate tests before implementation code.
