title: Jasmine: "Incomplete: No specs found" in Angular Typescript project
body: <p>For some reason I can't understand, Karma says that Jasmine can't find any of my test specs. I'm using Angular 9, Typescript and <code>ng test</code> to run the tests. I also ran <code>jasmine init</code> to create the jasmine.json config file. I've tried several config changes, creating a dummy test javascript file and more but I'm still getting the same "No specs found" message. This is getting really frustrating and I'm sure I'm just overlooking something obvious here.</p>
  
  <p>Tests folder structure:</p>
