Allow failing on undefined element/properties

[Dirk Van Haerenborgh]

Description

Since angular14, there is support for letting tests fail when encountering unknown components or directives:

angular/angular#36430 (comment)

Proposed solution

It's be great of this could be defined as follows:

  const createComponent = createComponentFactory({
    component: MyComponent,
    errorOnUnknownElements: true,
    errorOnUnknownProperties: true,
  });

or globally like (in test.ts):

import { defineGlobalsInjections } from '@ngneat/spectator';

defineGlobalsInjections({
    errorOnUnknownElements: true,
    errorOnUnknownProperties: true,
});

Alternatives considered

The issue comment talks about enabling this globally using

getTestBed().initTestEnvironment(
  BrowserDynamicTestingModule,
  platformBrowserDynamicTesting(),
  { 
    errorOnUnknownElements: true,
    errorOnUnknownProperties: true
  }
);

but I cannot get that to work, it keeps complaining:

  ● Test suite failed to run

    Cannot set base providers because it has already been called
