ng-mocks: Rendering mocked component ContentChildren broken after upgrade to ng9

I have a number of component tests in my project, that rely on mocking dependant components. Many of them also rely on rendering outlets in these mocked components.

Before upgrading to ng9, everything worked just fine. But now, the outlets aren’t rendered anymore. I’ve tried debugging, and I’ve found that in this line https://github.com/ike18t/ng-mocks/blob/master/lib/mock-component/mock-component.ts#L118 the viewContainer is always undefined.

If I explicitly disable Ivy ("angularCompilerOptions": { "enableIvy": false } in tsconfig.spec.ts), tests pass. The problem is, I can’t easily do this for all my libs.

Have you tried unit testing with Ivy enabled? I don’t see it being disabled in your tsconfig
