-To save some typing, you could also import a file with the above.
+By default if your testing framework exposes an `afterEach` hook (such as `jest` and `mocha`) then `cleanup` will be automatically invoked after each of your tests run.
+
+If you'd like to disable the automatic cleanup behavior described above you can import `@marko/testing-library/dont-cleanup-after-each`.
 
 ```javascript
-import "@marko/testing-library/cleanup-after-each";

-If you are using Jest, you can simply include `setupFilesAfterEnv: ["@marko/testing-library/cleanup-after-each"]` to your Jest config to avoid doing this in each file.
+With mocha you can use `mocha -r @marko/testing-library/dont-cleanup-after-each` as a shorthand.
