title: Does Angular's DestroyAfterEach option affect the speed of Jest tests?
body: <p><a href="https://angular.io/api/core/testing/ModuleTeardownOptions" rel="nofollow noreferrer">DestroyAfterEach</a> is a new option that was added in Angular 12.1, and promises to greatly speed up test performance (<a href="https://blog.ninja-squad.com/2021/06/25/what-is-new-angular-12.1/" rel="nofollow noreferrer">details here</a>). However, when making this change, I am not noticing any speed difference. I suspect this may be because I'm using Jest, which does not involve a browser.</p>
  <p>Is it expected that Jest does not have any speed improvements when applying this option? It's also possible I'm applying the option incorrectly.</p>
