I am using py.test and wonder if/how it is possible to retrieve the name of the currently executed test within the setup method that is invoked before running each test. Consider this code:

class TestSomething(object):

    def setup(self):
        test_name = ...

    def teardown(self):
        pass

    def test_the_power(self):
        assert "foo" != "bar"

    def test_something_else(self):
        assert True

Right before TestSomething.test_the_power becomes executed, I would like to have access to this name in setup as outlined in the code via test_name = ... so that test_name == "TestSomething.test_the_power".

Actually, in setup, I allocate some resource for each test. In the end, looking at the resources that have been created by various unit tests, I would like to be able to see which one was created by which test. Best thing would be to just use the test name upon creation of the resource.

You can also do this using the Request Fixture like this:

def test_name1(request):
    testname = request.node.name
    assert testname == 'test_name1'
