Tips for Unit Testing Vue Components with Jest
Achhunna Mali shows us some tips for Unit Testing Vue Components with Jest.
Using Jest to unit test Vue.js components can be tricky. We need a separate Vue Test Utils (@vue/test-utils) scoped package in order to virtually mount our components and use Jest to execute the tests. Because these two libraries work together, it’s important to make sure we don’t get confused about which API calls belong to which library. Along with these libraries, we also need to pay attention to JSDOM (virtual browser environment) specific methods, which comes with Jest. Having to juggle all this may be confusing and can discourage us from writing unit tests.
