angular 6创建TemplateRef的实例

Question

I have (angular 6) component and input parameter of TemplateRef<any> type

class TestComponent {
    @Input() tpl: TemplateRef<any>;
    ...
}

Now I want to create a test and I can't find the way how to create a template in test and set it as an input field.

In my HTML I have template like

<test>
    <ng-template #tpl>
        <div>OLOLO</div>
    </ng-template>
</test>

I need something like this

fixture = TestBed.createComponent(TestComponent);
component = fixture.componentInstance;
component.template = here I need instance of TemplateRef

Thanks

I didn't got why you are doing it this way, but if you want to access the template in spec file, instead of using input use viewchild in the component

so use code will be

class TestComponent {
  @ViewChild('tpl') public tpl: ElementRef;
  ...
}

and in spec.ts try this

it('should create', () => {
  console.log(component.tpl);
  expect(component).toBeTruthy();
});
