Wrong jasmine/wd2 typings in Angular 8/9 #17493
Description
I created a new blank angular 9 project using next commands:
ng new my-app
npm install
ng serve
I added then() to test:
Then run:
ng test
Error occured:
ERROR in src/app/app.component.spec.ts:20:30 - error TS2339: Property 'then' does not exist on type 'boolean'.
20 expect(app).toBeTruthy().then(() => { });
~~~~
After removing "@types/jasminewd2": "~2.0.3", from package.json, deleting then() of course and running:
npm install
ng test // no compilation error
Visual studio code reported that expect() matcher is sync method and returns boolean instead of Promise, just removed the .then() and everything works as it should.

Not really sure this is an Angular bug, but package @types/jasminewd2 comes by default I suppose.

The actual problem here is in the IDE, where it's picking up the incorrect typings.
This is pretty much the same root cause as #8138 and is currently being tracking internal TOOL-1368
