问题 Suppose I have a component I want to test that uses a very complex component. Furthermore it calls some of its methods using references obtained by @viewChildren . For example @Component({ moduleId: module.id, selector: 'test', template: '<complex *ngFor='let v of vals'></complex>' , }) export class TestComponent{ vals = [1,2,3,4] @ViewChildren(ComplexComponent) cpxs : QueryList<ComplexComponent> // .... } How can I replace the complex-component for a test double in `TestBed'? Something like

问题 I would like to test simple angular component with input. So an example in the bottom has little preparation for the test, and in a component should occur test function on blur, which shows log, but I have no logs in console. I tried 2 cases: getting div native element and click it and use blur() function for input native element. In angular app blur successfully occur, but it doesn't work in test. How can I fix it? @Component({ template: '<div><input [(ngModel)]="str" (blur)="testFunc($event
