[TIP] pytest fixture autouse question

[Pella,Chris]

I may have a misunderstanding of when session-level autouse fixtures are called. I am trying to create a session level fixture that runs before once per test session before any class setup is called.

I have conftest.py file in the directory where the tests reside and in there I have some code that installs some client software on the test node.  We only want to install the client once per session for all the test classes that get executed.

@pytest.fixture(scope="session",autouse=True)
def installer_fixture(request):
    """
    Installs client at the session level
    """
    print "installing"
    client = InstallClient()
    client.install()
    time.sleep(60)

    def uninstall():
        """
        Uninstall client
        """
        client.uninstall()

    request.addfinalizer(uninstall)


I assumed that this would execute prior to any test setup for a particular test class since it is a session level fixture, but I find that setup_class() executes before the clients get installed.

e.g. with some toy test code I find  that the class setup gets executed before the fixture.  This is not the behaviour I wanted or expected.

import pytest


class TestMe:

    def setup_class(cls):
        pytest.set_trace()
        print "setup"

    def test_one(cls):
        print "test one"

    def teardown_class(cls):
        print "teardown"




Thanks,
