<h3>Log Message</h3>
<pre>commitqueuetask should include more tests to ensure that the behavior
of PatchAnalysisTask._test_patch() is well defined
https://bugs.webkit.org/show_bug.cgi?id=137977
Patch by Jake Nielsen <jacob_nielsen@apple.com> on 2014-10-22
Reviewed by Alexey Proskuryakov.
* Scripts/webkitpy/tool/bot/commitqueuetask_unittest.py:
Adds the MockSimpleTestPlanCommitQueue class, which makes it easier
and more readable to define tests that are meant to test the behaviour
of PatchAnalysisTask._test_patch(), and adds several unit tests.
