schrodinger.test.pytest.sessionfixture module

Fixtures that are encoded into pytest and run as part of each test. These are never explicitly called and only used by test machinery.

schrodinger.test.pytest.sessionfixture.ensure_maestro_idempotent()

schrodinger.test.pytest.sessionfixture.ensure_JOB_SERVER_idempotent()

schrodinger.test.pytest.sessionfixture.ensure_LAST_EXCEPTION_cleared()

schrodinger.test.pytest.sessionfixture.disable_multiprocessing(monkeypatch)

Disable multiprocessing.Pool in all tests. This was causing memory issues in certain cases. Any test that tries to access multiprocessing.Pool will get an AttributeError when run.

schrodinger.test.pytest.sessionfixture.assert_mmffld_terminated(request)

For any future instantiations of different force fields (that is, with different custom default or custom parameters), mmffld is required to be fully terminated. The fixture here confirms that the global mmffld ref count has been brought back down to 0 at the end of each test.

schrodinger.test.pytest.sessionfixture.disable_show()

Change show() to a no-op for common top-level windows to reduce number of widgets that appear while running tests.

schrodinger.test.pytest.sessionfixture.disable_qmessagebox()

Change QMessageBox to raise RuntimeError so they won’t hang the test harness opaquely.

schrodinger.test.pytest.sessionfixture.prevent_jobdirdlg_jobhub_connection()

Prevent jobdirdlg from connecting to the jobhub callback. Connecting to this callback in multiple unit tests causes issues on Windows builds due to the short periodicity of the callback.

schrodinger.test.pytest.sessionfixture.use_mmpref_sandbox(tmpdir_factory)

Sets preferences (backed by QSettings) to a unique file. Allows parallel xdist tests to not stomp on each other.

schrodinger.test.pytest.sessionfixture.task_wait_with_default_timeout()

Set a default timeout when waiting on tasks in tests. If the default timeout is hit, then raise an error.

schrodinger.test.pytest.sessionfixture.task_cleanup_tmpdirs()

Clean up all tempdirs created by tasks.

schrodinger.test.pytest.sessionfixture.disallow_mock_in_swig(request)

schrodinger.test.pytest.sessionfixture.delete_job_manager(request)

schrodinger.test.pytest.sessionfixture.force_no_run_in_dir(pytestconfig)

Change back to the original working directory. The cwd is modified by the stupid run-in-dir option to our pytest for mmshare code (to be removed in PYTHON-3408), but this fixture this overrides that.

schrodinger.test.pytest.sessionfixture.check_current_thread_is_main_thread()

Raise an exception if the current thread is not the main thread

schrodinger.test.pytest.sessionfixture.start_qapp(config)

Start a qapp in this process.

schrodinger.test.pytest.sessionfixture.runtest_setup(item)

Execute each test in the directory where the test file lives.

Capture exceptions that occur outside of the main thread (for instance in event loops).

schrodinger.test.pytest.sessionfixture.runtest_teardown(item, nextitem)
