[FIXED] pytest - is there a way to ignore an autouse fixture?

Issue

I have this autouse fixture that will create a webdriver instance for each test:

@pytest.fixture(autouse=True)
def use_phantomjs(self):
    self.wd = webdriver.PhantomJS()
    yield
    self.close_wd()

However, some of our tests cannot run on PhantomJS due to a bug with one of our APIs. These tests can only run on Chrome (or Firefox), so I created another method for a webdriver instance using Chrome:

def use_chrome(self):
    self.wd = webdriver.Chrome()

which I plan to use on those tests, but I cannot get around the autouse fixture above.

Is there a way to somehow override the autouse fixture for some of our tests? I have tried using pytest.mark.usefixtures for each test but it doesn't seem ideal having to put that decorator on each and every test. Someone mentioned using metaclasses but I haven't fully understood how they work yet, so I was wondering if there was some other way that I might have missed.

Solution

----- UPDATE for latest versions of pytest----- use request.node.get_closest_marker() to get the marker. Refer get_closest_marker

You can achieve this in many ways , one way is to use the request fixture along with pytest mark fix. All you need to do is, create a new generic fixture

@pytest.fixture(autouse=True)
def browser(request):
    # _browser = request.node.get_marker('browser')
    _browser = request.node.get_closest_marker('browser')
    if _browser:
       if _browser.kwargs.get("use") == "chrome" :
            # Do chrome related setup
       elif _browser.kwargs.get("use") == "phantom" :
            # Do Phantom.js related setup
   else:
       # No mark up ,use default setup

and mark your tests like this

@pytest.mark.browser(use="chrome")
def test_some_chrome_test():
    # browser here would return chrome driver

@pytest.mark.browser(use="phantom")
def test_some_phantomjs_test():
    # browser here would return phantom driver
