Material-ui FloatingActionButton simulate click doesn't call onClick method

[ghost]

I admit testing material-ui is a headache generator.
The code is the same from #778 with shallow changed to mount.
The test is:

it('should enable TextField on click', () => {
       const props = {
           ongoingApi: false
       };
       const wrapper = mount(<TestComponent {...props}/>, testContext);
       wrapper.find('FloatingActionButton').simulate('click');
       assert.equal(wrapper.find('LockOpen').nodes.length, 1);
       assert.isFalse(wrapper.find('TextField').nodes.props.disabled);
   });

I checked and the onClick method of the FloatingActionButton is never called.
Thank you for your time

simulate does not work on "not a DOM node", so I wouldn't expect this to work unless FloatingActionButton renders a DOM node that has onClick={this.props.onClick}. What's the implementation of FloatingActionButton?

If you want to test FloatingActionButton, then shallow-render <FloatingActionButton />. If you're testing TestComponent, then all you need to assert is that it renders a FloatingActionButton with the right props.

In other words, I think you're trying to test too much in one file.

I am sorry I didn't explain. FloatingActionButton, TexField are material-ui component. The only component I try to test is InputLocker. The TestComponent is just a wrapper to be able to render the TextField as InputLocker's child.
FloatingActionButton has a "onClick" prop. Here is it's implementation material-ui/FloatingActionButton
I will take a closer look inside it also. I was hoping some other issue was related to mine and this could be solved with a quick fix that someone in the enzyme crew might now about.
Could it be something related to the "onTouchTap" implementation.
I added this in my test setup file:

import injectTapEventPlugin from "react-tap-event-plugin";
injectTapEventPlugin()

Thank you again.

You don't need to test material-ui's components, that's material-ui's job. All you need to test is that you're rendering its components with the correct props.

The props are definitely correct as long as rendered in the browser the component works perfect.

So, for everyone having problems with enzyme's simulate method on material-ui FloatingActionButtons components: simulate('click') does not work probably because the component is wrapped in a div which doesn't respond to an onClick event.
But if you do wrapper.find('FloatingActionButton').find('button').simulate('click') it does.

I was able to simulate on click on a material-ui component using the following code. I hope it can help others.

  it('should simulate click event on material-ui FlatButton', () => {
    const onSearchClick = sinon.spy()
    const wrapper = shallow(<LocationFinderSearch onSearchClick={onSearchClick} />)
    wrapper.find(FlatButton).simulate('click')
    expect(onSearchClick.called).toEqual(true)
  })
