### If 'Others', please specify the preferred domain.

Testing-TDD

### Particular directory path for the template.

`templates/Testing-TDD/Mocha-Express-Chai/`

### What tech stacks do you want to include?

Node.js, Express.js, Mocha, Chai, SuperTest

### Brief Description

This template provides an environment for testing an Express.js application using Mocha and Chai. It includes sample test cases for API endpoints, middleware functions, and utility modules. SuperTest is used to facilitate end-to-end HTTP testing.

**Key Features:**

1. Express Application: Set up a basic Express app with several routes and middleware.
2. Testing Setup: Configure Mocha as the test runner and Chai for assertions.
3. API Testing: Use SuperTest to make HTTP requests to your API endpoints within tests.
4. Mocking and Stubbing: Demonstrate how to mock dependencies using tools like Sinon.js.
5. Code Coverage: Integrate Istanbul/Nyc for code coverage analysis.
6. Error Handling Tests: Include tests that cover error scenarios and edge cases.

**Contributor Tasks:**

- Implement sample API routes with proper HTTP methods and status codes.
- Write unit tests for middleware and utility functions.
- Develop integration tests for API endpoints using SuperTest.
- Set up code coverage reporting and ensure high coverage percentages.
- Document how to run tests and interpret coverage reports in the README.
- Ensure the code follows best practices for Express.js applications.
- Create a corresponding markdown for populating [docs](https://universal-box.dev/) in `website/content/Templates/Testing-TDD/Mocha-Express-Chai.md` .. refer to [this one](https://github.com/Abhishek-Mallick/universal-box/blob/main/website/content/Templates/FullStack/EJS(SSR)%2BNodejs(Backend).md) for getting an idea on the format to follow
