Angular tests failing with Failed to execute 'send' on 'XMLHttpRequest'

Question

I am trying to test my angular 4.1.0 component -

export class CellComponent implements OnInit {
  lines: Observable>;
  @Input() dep         


        

Answer 1

You can either set input() property to default value in component.ts

@Input() tableColumns: Array = [];  
@Input() pageObj: any = '';

OR

Modify your component.spec.ts file in following way,

beforeEach(() => {  
   fixture = TestBed.createComponent(MyComponent);  
   component = fixture.componentInstance;  
   component.tableColumns = [];  
   component.pageObj = '';  
   fixture.detectChanges();  
});
