Component Tests

To create Jest tests for a component, create a folder called __tests__ at the top level of the component’s folder. Save the tests inside the __tests__ folder.

1myComponent
2    ├──myComponent.html
3    ├──myComponent.js
4    ├──myComponent.js-meta.xml
5    ├──myComponent.css
6    └──__tests__
7        └──myComponent.test.js

Jest runs JavaScript files in the __tests__ directory. Test files must have names that end in .js, and we recommend that tests end in .test.js. You can have a single test file with all of your component tests, or you can have multiple files to organize related tests. Test files can be placed in sub folders.
