Convert Simpletests to PHPUnit

@socketwench

Yep you have struck a known core wide problem

Also of note is that there is no replacement for drupalPostAjaxForm.

from https://www.drupal.org/node/2469723

I am posting the full paragraph below.

but it looks like we need to locate the link and "->click()"
.. as always I am posting early in an attempt to be helpful - I will try and find sometime over the weekend to actually do something about this :)

Please note that BrowserTestBase does not yet have feature parity with WebTestBase, in particular the verbose output (#2469721: Add functionality to store browser output to BrowserTestBase).
Also of note is that there is no replacement for drupalPostAjaxForm. The Goutte driver doesn't support JavaScript and we decided instead of adding in hacks to support drupalPostAjaxForm we'd be better served working towards real JavaScript support, in the form of a JavaScript based driver. Step 2 (#2469713: [Needs change record updates] Step 2: Create a JavaScriptTestBase using PhantomJs Driver/Binary) will introduce a JavaScript capable driver and Ajax form interactions will be performed with code like

$this->getSession()->getPage()->find('css', '#somebutton')->click();
If the #some-button element has Ajax behaviors, they'll fire instead of the form submit.

The future is now, JavaScriptTestBase exists :)

So yes, any test that is doing (fake) ajax testing will need to be converted to a JS test. Which in turn will allow for way better tests.

See https://www.chapterthree.com/blog/javascript-testing-comes-to-drupal-8

Yes, definitely. JS tests run in an actual browser (phantomjs, no UI but executes all JS and so on), which makes it considerable slower.

I'd recommend to have one dedicated test for the UI and otherwise use the API to create the flags.

Here is a candidate for our first test that extends javascriptTestBase

I want to break this up into manageable chunks .... here is an simple conversion.

Next weeks target.
