You can use teaspoon it runs your favorite test suite (default is jasmine) and they have a wiki to integrate with angular. Teaspoon integrates with the asset pipeline, so you can throw all the angular gems in there and require them in the teaspoon generated spec_helper.js. The other cool thing is: they have a guard … Read more
You have to understand the mechanics behind Typescript and the spying. First on Typescript … I’m ignoring the extra parens in class Parent(). Typescript uses prototypal inheritance behind the curtain. Thus a prototype will copy the referenced properties from the “base class” to the new class. This is what the for loop does in the … Read more
Here is my solution for the ones using Rxjs 6 let mockService = { getData: () => { return of({data:’any data’}); } } spyOn(mockService , ‘getData’).and.callFake(() => { return throwError(new Error(‘Fake error’)); });
It turns out this is due to using ChangeDetectionStrategy.OnPush in the component. Using OnPush only allows you to call .detectChanges() one time, so subsequent calls will fail to do anything. I’m not familiar enough with Angular to fully understand why. I was able to produce the required behaviour by overriding the ChangeDetectionStrategy in my TestBed … Read more
can just do: import { MatIcon } from ‘@angular/material/icon’; import { MatIconTestingModule } from ‘@angular/material/icon/testing’; describe(‘MyComponent’, () => { beforeEach(async(() => { TestBed.configureTestingModule({ declarations: [MyComponent, MatIcon], imports: [MatIconTestingModule], }).compileComponents(); })); … }); This will generate a test icon rendering without the HTTP request. NOTE: Newer versions of Angular, e.g., >16, may produce an error unless … Read more
In short, just debug jasmine-node: node –debug-brk node_modules/jasmine-node/lib/jasmine-node/cli.js spec/my_spec.js If you look at the source of the jasmine-node script, it just invokes cli.js, and I found I could debug that script just fine. I wanted to use node-inspector to debug a CoffeeScript test. Just adding the –coffee switch worked nicely, e.g. node –debug-brk node_modules/jasmine-node/lib/jasmine-node/cli.js –coffee … Read more
There is no way to test those functions. Their scope is the function that comprises your BracketService factory and they are invisible anyplace else. If you want to test them, then you have to expose them somehow. You can move them into their own service (which seems like overkill) or you can black box test … Read more
After your call to promise.resolve(): Call $timeout.flush(). This will force a digest cycle and propagate the promise resolution Call done(). This tells Jasmine the async tests have completed Here’s an example (Demo on Plunker): describe(‘AngularJS promises and Jasmine 2.0’, function() { var $q, $timeout; beforeEach(inject(function(_$q_, _$timeout_) { // Set `$q` and `$timeout` before tests run … Read more
Since I didn’t got debugger; to work I found another solution. By adding the following to my test, resharper won’t be notified that the test has finished so we can set debug breakpoints in the opened browser (I use chrome) and update (F5) the page. jasmine.getEnv().currentRunner_.finishCallback = function () {}; Since Jasmine 2.0 you need … Read more
Try to specify the position of toaster otherwise it will give null Inject error app.module.ts imports: [ BrowserModule, AppRoutingModule, HttpClientModule, BrowserAnimationsModule, FormsModule, BsDropdownModule.forRoot(), ToastrModule.forRoot({ positionClass :’toast-bottom-right’ }) ],
