Description

For continuous integration it's helpful to be able to acquire a list of test names so that the tests can be split and load balanced across multiple executors.

We also do multiple builds containing the same tests run with different parameters. It's helpful to be able to tag the test names so they junit.xml output can be merged by other tools for reporting.

There are also issues with nosetests and specifying many tests cases from the command line where nosetests hits recursion limits in Python. Increasing the maximum recursion depth seems to address the issue for now.
