i have a function in service in which i have 3 http get calls and i return the response with forkJoin making an array, how will i test this service funtcion in spec.ts ?
this is the function in my registration component which is calling the service,



this.register.registrationData()
.subscribe(data => {
this.types = data[0];
this.modules = data[1];
this.packages = data[2];
});


and this is my registration service function,



registrationData(): Observable<any> {
const companyTypes =this.http.get(ConstantService.apiRoutes.companyTypes);
const modules = this.http.get(ConstantService.apiRoutes.modules);
const packages = this.http.get(ConstantService.apiRoutes.packages);
return forkJoin([companyTypes, modules, packages]);
}


this is my spec file so far,



 it('Should require registration data', () => {
loginRegService.registrationData().subscribe((data) => {
expect(data).toEqual(regData);
})
const reqCompany = httpTestingController.expectOne(`${environment.apiUrl}/anonymous/companyTypes/`);
const reqModule = httpTestingController.expectOne(`${environment.apiUrl}/anonymous/modules/`);
const reqPackage = httpTestingController.expectOne(`${environment.apiUrl}/anonymous/packages/`);
expect(reqCompany.request.method).toBe('GET');
expect(reqModule.request.method).toBe('GET');
expect(reqPackage.request.method).toBe('GET');
const e1 = forkJoin([reqCompany, reqModule, reqPackage]);
reqCompany.flush(companyType);
reqModule.flush(modules);
reqPackage.flush(packages);
});

In your approach to testing this, you are mocking up HTTP observables - which is a good way to test HTTP calls in Angular.



However if you are looking for a more generic way of testing rxjs, you can use their marbles library.



In fact I wrote an example using forkJoin which you can find here.
