storybook-code-coverage VS mocha

We are going to use this repo as an example: penx/storybook-code-coverage, authored by Alasdair McLeay. The author wrote a detailed article about the set-up of this repo: Combining Storybook, Cypress and Jest Code Coverage. This repo uses Jest for unit tests, Cypress for integration tests, and Storybook for visual previews. Each module generates their own test coverage reports, which can be merged together into one report. The original repo doesn't have a GitHub workflow to build the entire project, but we will add one as part of this portfolio.

Using something like Vitest, Jest, or Mocha didn't work because:

MochaJS is a feature-rich JavaScript test framework running on Node.js, making it a popular choice for both backend and frontend testing. It's known for its flexibility and straightforward syntax, allowing for asynchronous testing and the use of any assertion library.

We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I don’t want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go!

JavaScript Popular tools for testing: Mocha, Jasmine, Unit JS, Jest

To execute your tests, you can create test scripts using popular testing frameworks like Mocha, Jasmine, or Jest. These frameworks provide a structured way to organize and run your tests, report results, and handle assertions.

⚗️ Mocha and Chai for testing

Testing frameworks like Jest, Mocha, and Jasmine are crucial for software development, ensuring code reliability and correctness. They offer features like test suites, test cases, assertions, and asynchronous testing support.
