Project mention: Scaling Cypress Tests: Parallelise your End-to-End Tests with Testkube | dev.to | 2024-10-28
However, starting with version 12, Cypress blocked projects using the 'cypress-cloud' module, impacting these third-party services. SorryCypress now only works with older Cypress versions, while Currents.dev has ended its official support for Cypress. This change has disrupted many teams' testing workflows.

Mocha is a feature-rich JavaScript test framework that runs on Node.js, making asynchronous testing simple and enjoyable. It provides functions that execute in a specific order, collecting test results and offering accurate reporting.
-
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!

Like many other companies with mature software, we found ourselves at a crossroads with our React application. The app, initially developed in early 2019, was built with React 16 and used Enzyme for unit testing. Over the past five years, the app grew, evolved, gained new features, and went though minor and major refactorings. Obviously, as responsible engineers we always maintained unit test coverage around 70-80%. However, our React version had remained unchanged.

Jasmine is a BDD testing framework for Node.js projects and other JavaScript applications. The library comes with no external dependencies, so it is simple to use with a low overhead. It's the oldest of the three tools we've covered, having been around since 2010. Jasmine runs on any JavaScript platform and is compatible with other testing libraries.

Libraries like Sinon.JS provide robust support for stubs and spies, enabling precise control and inspection of your code's interactions. By favoring stubs and spies, you can keep your tests concise, easier to understand, and less prone to errors.
-
istanbul
Yet another JS code coverage tool that computes statement, line, function and branch coverage with module loader hooks to transparently add coverage when running tests. Supports all JS coverage use cases including unit tests, server side functional tests and browser tests. Built for scale.
-
chai
BDD / TDD assertion framework for node.js and the browser that can be paired with any testing framework.
Unit Testing: Yes, Rest APIs can also be tested using unit tests. This involves executing the HTTP requests and validating the result. Although this method initially requires more effort, it offers the advantage of complete integration into your development process and enables continuous testing. Each programming language has its own tools. I mainly develop with JavaScript, so I can show you a practical example here. I use Mocha and Chai as testing frameworks. For each test, one or more requests are sent to the corresponding Rest API endpoints and the result is validated.

The tooling for testing JavaScript was far from what we have today, neither was the editor support. To test code that manipulates the DOM, you basically needed to run them in a browser. For that purpose we had an HTML page that would load QUnit, our test code, and our production code.
