Documentation of componentOutputs looks not enough. #368
Description
Summary
When render(ComponentType) includes componentOutputs in its option, TypeScript inference seems broken.
Repro
BTW, I'm preparing a bugfix for this. This is a spec to reproduce the bug.
describe('componentOutputs', () => { it('invokes given callback when an output is emitted', async () => { @Component({ template: `` }) class TestFixtureComponent { @Output() event = new EventEmitter<void>(); emitEvent() { this.event.emit(); } } const spy = jest.fn(); const { fixture } = await render(TestFixtureComponent, { componentOutputs: { event: spy }, }); fixture.componentInstance.emitEvent(); expect(spy).toHaveBeenCalled(); }); }); projects/testing-library/tests/render.spec.ts:170:31 - error TS2769: No overload matches this call.
