py.test SetUp/TearDown for whole test suite
You could use pytest-xvfb instead of messing with this… It would be easier.
It is actually fairly simple. Create a file called conftest.py in your project root which contains this:
import pytestimport osimport subprocessimport tempfile@pytest.fixture(scope="session", autouse=True)def start_xvfb_server (request): tempdir = tempfile.mkdtemp() xvfb_cmd = ['Xvfb', ':1022', '-screen', '0', '800x600x24', '-fbdir', tempdir, '-noreset' ] xvfb_proc = subprocess.Popen(xvfb_cmd, stdout=open(os.devnull), stderr=open(os.devnull), shell=False ) request.addfinalizer(xvfb_proc.kill)Now, all you have to do is to set up each tests to set the DISPLAY to 1022 which is trivial to do.
Alternatively, you can simply define setUpClass / tearDownClass methods, as described in the unittest module documentation:https://docs.python.org/2/library/unittest.html#unittest.TestCase.setUpClass
Since py.test v2.4, they are fully supported.This official documentation page also documents all xunit-style compatible methods:https://pytest.org/latest/xunit_setup.html
