MockRender function input

[cheng93]

const funcInput = () => '123';
fixture = MockRender(TestComponent, {
  funcInput
});

I believe funcInput gets autowired to be an output.

Is it possible to pass a function input in MockRender

Hi @cheng93,

that's not true. funcInput will be set as @Input or @Output of TestComponent only when TestComponent has such an input or output.

If TestComponent has neither, then nothing will be done with funcInput.
if TestComponent has @Input() funcInput, then this.funcInput will be the function.
if TestComponent has @Output() funcInput, then funcInput will be triggered on emits of this.funcInput.

any idea why my test is failing then?

Aha, I see, that makes sense, because inputs are wrapped.
Could you tell me why you need to assert that MockRender is passing parameters to components correctly?

Ah I think my example was too simple, I also can't remember exactly what I was doing that caused me to ask this question.

I think it was along the following.
