mochajs/mocha-examples

Mocha-examples is a collection of working example projects that demonstrate common configurations and use cases for Mocha, a JavaScript test framework.

The repository addresses the challenge of learning how to set up Mocha in different environments and with different tools. Rather than providing abstract documentation, it offers concrete, runnable examples that developers can clone and execute immediately. Each example is self-contained within its own package and includes the necessary configuration to work out of the box, eliminating the guesswork involved in integrating Mocha with specific frameworks or tools.

Developers should choose this repository if they are setting up Mocha for the first time or integrating it into a new type of project. The examples cover a wide range of scenarios including testing GraphQL APIs with Apollo Server, REST APIs with Express, browser-based applications, TypeScript projects with various loaders, and testing frameworks like Playwright, Puppeteer, and Selenium. Someone evaluating whether to use these examples should know that each one includes its own npm test command that runs in CI, ensuring the examples remain functional. The repository is organized as a monorepo using Lerna, making it easy to browse multiple examples and understand how Mocha adapts to different technology stacks.

Development activity shows consistent maintenance of the example collection. The project accepts contributions through pull requests, with a straightforward process for adding new examples by creating a folder under packages and running npm init. The maintainers recommend code formatting with Prettier but do not enforce strict linting requirements across examples, keeping the barrier to contribution low. Each example specifies its own Node.js version requirement, indicating attention to compatibility across different project setups.
