Nose tests will allow specific tests to be selected per the documentation at
https://nose.readthedocs.org/en/latest/usage.html#selecting-tests.  These are
indicated with the optional parameter (test_path).  A few examples are:

Run all TestUserInfo functional tests:
    ./run_tests.sh test/functional/test_user_info.py:TestUserInfo

Run a specific API test requiring the framework test tools:
    ./run_tests.sh -with_framework_test_tools -api test/api/test_tools.py:ToolsTestCase.test_map_over_with_output_format_actions


Extra options:



 --verbose_errors      Force some tests produce more verbose error reporting.
 --no_cleanup          Do not delete temp files for Python functional tests (-toolshed, -framework, etc...)
 --debug               On python test error or failure invoke a pdb shell for interactive debugging of the test
 --report_file         Path of HTML report to produce (for Python Galaxy functional tests).
 --xunit_report_file   Path of XUnit report to produce (for Python Galaxy functional tests).
 --dockerize           Run tests in a pre-configured Docker container (must be first argument if present).
 --db <type>           For use with --dockerize, run tests using partially migrated 'postgres', 'mysql', 
                       or 'sqlite' databases.
