Leveraging Jasmine-DOM for Angular Applications

I've been working on an Angular 10 CLI project (v10.1.2) and recently installed 

@testing-library/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="01606f66746d60734130312f312f33">[email protected]</a>
. I'm really interested in using the convenient matchers like .toBeInTheDocument(), but I'm a bit stuck because I'm running Karma with Jasmine (configured via Angular) and Typescript. How can I get the @testing-library/jasmine-dom matchers installed?

I attempted to follow the latest version's instructions (v1.1.0), and although I can see the matchers on the HTMLMatchers type in VSCode, I'm having trouble actually adding them. When I try to import them with 

import JasmineDOM from '@testing-library/jasmine-dom';
, I receive an error stating that 
File C:/.../node_modules/@types/testing-library__jasmine-dom/index.d.ts
is not a module.

Given that this project is an Angular CLI setup with Jasmine running under Karma, do you think it would be more practical to use a Karma plugin instead? (I haven't come across any yet...)

Answer №1

We collaborated with the developer of jasmine-dom to rectify a CSS library bug that was causing compatibility issues with Karma. The documentation has been updated, so integrating it should now be seamless!
