it('should ...', inject([XService], (service: XService) => {
expect(service).toBeTruthy();
}));
This way I can use service inside 'it'. There is a lot more 'it' and I don't want to inject service every time. I would like to inject the service once somewhere at the start (in beforeEach for example) but I can't. xService has a lot of dependencies inside constructor which I'd like to get also.
The only way I could've done this was to set all those values inside the first 'it'.
let xService: XService;
let yService: YService;
let zService: ZService;
beforeEach(() => ...);
it('should ...', inject([XService], (service: XService) => {
xService = service;
yService = xService['yService'];
zService = xService['zService'];
expect(xService).toBeTruthy();
}));
But personally I thinks this is an ugly solution. Can I in some way move it to beforeEach?
Instead of inject, try using TestBed.get(). It's basically the same functionality, and your problem can be solved with it easily:
let xService: XService;
let yService: YService;
let zService: ZService;
beforeEach( () => {
TestBed.configureTestingModule( ... ).compileComponents();
xService = TestBed.get( XService );
yService = TestBed.get( YService );
zService = TestBed.get( ZService );
} );
it( 'should ...',() => {
expect( xService instanceof XService ).toBe( true );
} );
