For reference, pull request #235 contains test cases that illustrate/specify the behaviour described in my previous comment. While PR #252 is not merged, you can already install a pytest candidate for this fix: which should give you pytest-2.7.0.dev1 containing the fix. Support for headless and headful execution. pytest-server-fixtures: fix deprecation warnings when calling pymongo.

If you do, fixtures defined in these lower-level conftest.py files will be available to tests in that directory and subdirectories. In this conftest file you can see the use of: before you could run tests on a subdir project/foo/test.py and project/conftest.py fixtures were magically discovered and usable Some people used this as a feature, I think it has always been a bug. https://bitbucket.org/pytest-dev/pytest/issue/616, "fixture is being applied more than once to the same function" in 3.6.0, not in 3.2.1.

We can put fixtures into individual test files, if we want the fixture to be only used by a single test file. If a faker_locale fixture is active for a test, the faker fixture will fallback to returning a new Faker instance for that test (function-scoped), so if you do not like to use the session-scoped Faker instance, just define and activate a faker_locale fixture in the appropriate place in accordance to how pytest handles fixtures. relative to the "common rootdir" of a test run which is determined by He triggered a fix wrt conftest visibility. Write end-to-end tests for your web apps with Playwright and pytest. Find attached in the patch a test thats is failing on 2.6.3 and above, and passing < 2.6.3. Fixtures are a powerful feature of PyTest. They now are always When fixture function is called, it will run the code in the function from the beginning until it hits yield statement which serves as the "setUp" code and the code after the yield statement serves as the "tearDown" code. finding a common ancestor of all testrun arguments. All files in the directories (except for the logs) are python files. pytest will build a string that is the test ID for each set of values in a parametrized test. The tests will look for fixture in the same file. Each conftest.py provides configuration for the file tree pytest finds it in. This will take effect even if you’re using the pytest.mark.asyncio marker and not the event_loop fixture directly.
