Building a predictable and error-free software is something each developer should strive for. Using automated testing allows you to sleep soundly at night as you know for sure your code works properly. A good Javascript testing framework may become your sleeping pill.
Theoretically, it is possible to test an app without using automated testing tools, but in reality, it involves additional stresses like writing helper functions, command-line utilities, feeling anxious about how to run asynchronous tests and so on. Eventually, you will end up building your own custom test automation framework. No need to reinvent the wheel.
JavaScript, like any other programming language, has a number of tools that allow test-driven development, like Jest, Jasmine, Mocha, QUnit, Karma, Cypress, and others. But choosing among testing frameworks turned out not to be an easy task. So, this article will be useful for those who face the same situation and are looking for a suitable testing tool to use.
