How do you test Node.js applications? The Node.js Test Runner is a stable, modern, fast, and doesn't require additional libraries. But understanding and using it well can be tricky. Attendees will learn how to use Node.js test runner to its full potential. You will see how it compares to other tools, how to set it up, and how to run your tests effectively. During the workshop you will get comfortable with filtering, native assertions, running parallel tests, using CLI, and much more. We will also talk about working with TypeScript, custom reporting, and code coverage.
