提供“entryComponents”对于TestBed [英] Providing "entryComponents" for a TestBed

问题描述

我有一个组件，它接收组件的组件类，以动态创建为子组件。

I have a component which receives a component class of component to dynamically create as a child.

let componentFactory = this.componentFactoryResolver.resolveComponentFactory(componentToCreate);
this.componentReference = this.target.createComponent(componentFactory);

我正在尝试编写单元测试并传递一些TestComponent来创建&渲染。

I'm trying to write a unit test and pass some TestComponent for it to create & render.

TestBed
  .configureTestingModule(<any>{
    declarations: [MyAwesomeDynamicComponentRenderer, TestHostComponent],
    entryComponents: [TestComponent],
  });

铸造为any因为 configureTestingModule 期望 TestModuleMetadata 哪个没有 entryComponents 但是我收到错误：找不到TestComponent的组件工厂。

There is casting to "any" because configureTestingModule expects TestModuleMetadata which doesn't have entryComponents but I get error: "No component factory found for TestComponent".

如何将 entryComponents 提供给 TestBed ？

推荐答案

如果需要，您也可以直接在测试文件中输入：

You can also do it into your test file directly if you want :

TestBed.configureTestingModule({
  declarations: [ MyDynamicComponent ],
}).overrideModule(BrowserDynamicTestingModule, {
  set: {
    entryComponents: [ MyDynamicComponent ],
  }
});
