Document how to test keyboard events?

Thanks for the super-handy component!

It took me a while to figure out how to test keyboard events when using jsdom. Maybe you'd want to add a section on testing to the README?

FYI see jsdom/jsdom#1634 (comment).

Hi @ronen , for test, I use simulate-event to simulate keyboard events. It works well for my case.

Testing with jsdom is outside of the scope of this react component.

I'm also trying to test a keyboard event. Here is the text of my test:

it('triggers change in environment with arrow keys', () => {
wrapper.find('t').simulate('keydown', { keyCode: 39 });
expect(defaultProps.setServerTypeHandler).toHaveBeenCalledWith('transient');
});

In this case, the function that contains the call to setServerTypeHandler, which is the function that gets called on the keyboard event, is not getting called in the test - I have checked this in the test coverage, and neither the onKeyEvent nor the function, handleKeyPress, are covered. Is there a reason for this?
