Test the admin forms

Still need to test the plugin selection form.

Apparently tags don't show up in filter/tips after being disabled - UNLESS we put a particular debugging dsm() into the XBBCodeFilter constructor.

No, I don't know why.

The drupal_set_message() fixes the problem even if it's empty. I'm pretty baffled.

Of course it's a caching issue. :facehoof:

protected function WebTestBase::refreshVariables
8 WebTestBase.php protected WebTestBase::refreshVariables()

Refreshes in-memory configuration and state information.

Useful after a page request is made that changes configuration or state in a different thread.

In other words calling a settings page with $this->drupalPostForm() with a changed value would update configuration to reflect that change, but in the thread that made the call (thread running the test) the changed values would not be picked up.

This method clears the cache and loads a fresh copy.

refreshVariables() didn't help.

Eh. It seems that logging in as a different user makes it work. Since the testcase does that anyway to visit node/add/page just a few lines later, I'll just move the login() call ahead a bit.

Two more parts:

1. Rename a tag.

2. Use format specific settings.

Renaming should happen in the regular plugin test case.

Let's see if the testbot can handle this.

Hm.

Is this thing on?

Yaaaaaaay! :D :D

Well, on the bright side, it's not a bug in the test. The form really does block changing a name until you've already enabled it and saved.

Retest with #2629662: Can't rename tags while enabling them.

Variable name error.

Herpaderp let's just generate a random mixed-case machine name to put into a field that requires lower-case. >_<

(Come to think of it, the validator absolutely needs to be tested too.)

Next round:

- Form validation
- Format-specific settings.

Form validation.

Next: Finally, the format-specific stuff.

Last one.

I forgot how to drupalPostForm.

And also forgot how to prefix the entity plugins.

And done.
