I'm unable to find time to test this, but would like to merge. Please confirm you've tested in both React v16 and v15. Thanks for all of your work on this!

[shivgarg5676]

I have checked only on react v15.4.2 as it was in dev dependencies. All the test cases are getting passed and i did manual test as well. I will do a quick sanity on react v16. I will comment back when done

[shivgarg5676]

As this package has been deprecated and is moved to react-dom/test-utils. We may need to update our entire test suite to run unit tests on react 16.
As I am a newbie, please guide how to test for react 16.

I’m not certain this is absolutely needed, but if you want to upgrade the test suite and are running into a specific issue, let me know what the issue is so I can advise.

Please guide how to test for react 16. I have tested by importing to my project and tested manually it is working but i am unable to run test suite using react 16.

I tried as follow but failed.

1. Upgraded react and react-dom version to 16.4.1
2. run npm install
3. run test suite.

I am getting following error
Error: Cannot find module "react-dom/lib/ReactTestUtils" as this package has been moved to react-dom.

I have read here and there and people say that you need to import react-test-utils from react-dom/test-utils.

That sounds like a good place to start.

I have tested on react 16. all test cases are getting passed on react-16. it is good to be merged
Should I commit new test suite working on react 16 or should we keep old test suite for react 15.

Sorry for the delay i got busy with few tasks at my office.

While I do want to maintain backwards compatibility w/ v14 & 15 to avoid a breaking change (and this is quite important), please commit your code that focuses on React 16 as I'd of course like to focus on that for the future.

[shivgarg5676]

All of my code in this branch is backwards compatible and is working fine on both react v15 and v16. You can merge this branch, I will create a new branch with the updated test suite.

[rnicholus]
