I am using Angular 14, when trying to use the last version of the angular-testing-library, today 14.0.0, it was not working because this latest version only works with Angular 15. This is due to the isStandalone vs eisStandalone breaking change in Angular.
I had to use versions < 13.1.0 of the Angular testing library to make it work with Angular 14. Since the angular-testing-library does not follow the same versions number as Angular, at least we could have such guidance in the Readme file. Alternatively, the library versions can match the Angular version it matches, as other libraries for Angular does.
