Context menu issues when attempting to run Python tests

I currently have a variety of issues when attempting to executing Python py.text test cases. This began sometime this calendar year after upgrading the IDE. As a workaround I have simply been executing tests from the command line, and finally have some time to troubleshoot this.

• Mac OSX Sierra 10.12.6
• Python 2.7.13
• Pytest 3.2.1 and 3.2.5

1. The right-click context menu no longer provides class and testcase execution options, only a general "Run" for the entire module. 

2. My existing test code won't invoke Pytest in the context menu at all. It appears it's trying to run Unittest instead. I haven't definitively narrowed down why my existing test modules won't show pytest at all, but it seems related to having setup_method() and teardown_method() in my test classes. If I comment those out then pytest appears as a runner. Though I've whipped up a very simple shell of a test module with setup_method() and teardown_method() and it currently shows pytest as a runner in the context menu.

I've cleared ALL of the run configurations, invalidate caches, have tried the following builds all of which exhibit this issue:

• 2017.2.6
• 2017.3 RC
• Pycharm CE 2017.2   

However, if I go all the way back to Intellij 2016.3.7 everything works great and as expected. For what I'm doing this is probably acceptable.
