Mastering React Test-Driven Development

Drying up DOM events

There's still more that we can do. Those ReactTestUtils.Simulate.* calls can be shortened and made a little easier to read.

If you do a search in the code base for these calls (for example, by running git grep ReactTestUtils.Simulate on the command line), you'll see that we use three functions on the Simulate object: click, change, and submit. We can deal with these by adding new properties onto the returned value from createContainer.

The first two functions, click and change, will be simple pass-throughs to the ReactTestUtils.Simulate call of the same name. We'll pull out a helper function, named simulateEvent, that we can re-use for each of the events.

The third function, submit, needs a little extra work. All our ...
