Here in Syndicode we have told you many times that Vue has a great future. First of all, its benefits make it easier to use. Secondly, it has Jest, and Jest makes testing Vue easier.

Setting up the testing environment is easy:

  1. We start off by importing Vue and the necessary components that we want to test.
  2. We use describe to encapsulate numerous unit tests surrounding our FancyHeadingcomponent.
  3. Each unit test is created with the it function, firstly providing a description of exactly what we’re testing, followed by a function.
  4. Finally, we assert that this is true by using expect. If we check our terminal with $ npm run test:unit --watch, we’ll see a PASS for this unit test.
  5. To use TypeScript in your tests install @babel/preset-typescript and add it to your Babel config.

Jest can be used in projects that use Webpack to manage assets, styles, and compilation. Webpack does offer some unique challenges over other tools.

Don’t forget that rethinking frontend testing will help you to create maintainable web applications easily!
