.ts file
It seems that the default test case is not running because of the error cannot read properties of undefined. I tried to search that in .ts file but didn't find solution. And not only for this component but for every component it is giving the same error. Atleast the default tests should have run.

Solution
You have several dependencies invoked from your component.
HeaderComponent
|
V
DailyplanningService
|
V
AppConfigService
|
V
?????????? (perhaps next dependencies)
So error is thrown from AppConfigService
service after calling this.configService.getConfig()
method from the DailyplanningService
constructor.
That way you would have to mock AppConfigService
instance from the providers array. Perhaps you have to mock more things, but from code, now I can only see the getConfig
method has to be mocked.
beforeEach(async () => {
await TestBed.configureTestingModule({
imports: [RouterTestingModule,
HttpClientTestingModule],
providers: [
{
provide: AppConfigService,
useValue: {
getConfig: () => ({
baseUrl: 'dummy-url',
serviceBase: 'api-base'
})
}
}
],
declarations: [ HeaderComponent ],
schemas: [CUSTOM_ELEMENTS_SCHEMA]
})
.compileComponents();
});
