From 82f5cb283efffe96e1b6cd634738e0e7de2cd90a Mon Sep 17 00:00:00 2001 From: Maciej Strzelczyk Date: Fri, 4 Mar 2022 16:18:50 +0100 Subject: [PATCH] feat: Adding support for pytest-xdist and pytest-parallel (#1365) Closing #1364 Auto-add parameters for `pytest` when we detect that `pytest-xdist` or `pytest-parallel` are installed through the `requirements.txt` or `requirements-test.txt` files. Setting the options to auto, as we can't assume what's the best number would be for the various environments the tests will run on. --- .../templates/python_samples/noxfile.py.j2 | 80 +++++++++++-------- 1 file changed, 46 insertions(+), 34 deletions(-) diff --git a/synthtool/gcp/templates/python_samples/noxfile.py.j2 b/synthtool/gcp/templates/python_samples/noxfile.py.j2 index 20cdfc620..4c808af73 100644 --- a/synthtool/gcp/templates/python_samples/noxfile.py.j2 +++ b/synthtool/gcp/templates/python_samples/noxfile.py.j2 @@ -188,42 +188,54 @@ def _session_tests( # check for presence of tests test_list = glob.glob("*_test.py") + glob.glob("test_*.py") test_list.extend(glob.glob("tests")) + if len(test_list) == 0: print("No tests found, skipping directory.") - else: - if TEST_CONFIG["pip_version_override"]: - pip_version = TEST_CONFIG["pip_version_override"] - session.install(f"pip=={pip_version}") - """Runs py.test for a particular project.""" - if os.path.exists("requirements.txt"): - if os.path.exists("constraints.txt"): - session.install("-r", "requirements.txt", "-c", "constraints.txt") - else: - session.install("-r", "requirements.txt") - - if os.path.exists("requirements-test.txt"): - if os.path.exists("constraints-test.txt"): - session.install( - "-r", "requirements-test.txt", "-c", "constraints-test.txt" - ) - else: - session.install("-r", "requirements-test.txt") - - if INSTALL_LIBRARY_FROM_SOURCE: - session.install("-e", _get_repo_root()) - - if post_install: - post_install(session) - - session.run( - "pytest", - *(PYTEST_COMMON_ARGS + session.posargs), - # Pytest will return 5 when no tests are collected.
