`Schema validation failed` Error when running tests and updating @angular-builders/jest from `7.3.1` to `8.0.1`

Firstly, apologies if this has already been answered. I can’t seem to find any issues or comments with this error.

I have just updated my version of @angular-builders/jest from 7.3.1 to 8.0.1. From what i understand, issues should be raised here. When I run my tests I now get the following error (it was working fine before):

Schema validation failed with the following errors:
  Data path ".builders['run']" should have required property 'class'.
Error: Schema validation failed with the following errors:
  Data path ".builders['run']" should have required property 'class'.
....

I can’t see anything in the doc’s to advise me what this issue might be, I guess there is a breaking change, but i don’t use transform or global in my configurations.

I would like to update this as my code coverage is a bit misleading at the moment.

Hopefully, someone here knows what the issue is.

Can confirm that it works with Angular v8!

Here the changes I had to make from a newly generated Angular app to make the tests run in jest.

great stuff!

just dont delete the fakeAsync from tests, what if we want to test asynchronously? solution: add these 2 imports on 1st line of setup-jest.ts import ‘zone.js’; import ‘zone.js/dist/zone-testing.js’;

and in jest.config.js i had to change setupFilesAfterEnv to

setupFilesAfterEnv: [‘<rootDir>/setup-jest.ts’],

Also, those are needed in same file for tests to work properly:

import { TestBed } from ‘@angular/core/testing’; import { BrowserDynamicTestingModule, platformBrowserDynamicTesting } from ‘@angular/platform-browser-dynamic/testing’; TestBed.initTestEnvironment(BrowserDynamicTestingModule, platformBrowserDynamicTesting());

Thanks
