测试: 在 pytest 下,严格的位置参数强制执行会被忽略

Steps to reproduce

Check out the main branch of google-api-Python-client.
Set up a clean virtual environment and install test dependencies (pytest, mock, parameterized).
Run the strict positional parameters enforcement test directly using pytest:

bash

pytest tests/test_discovery.py -k test_tests_should_be_run_with_strict_positional_enforcement

Code example

The bug lies in how strict argument enforcement is configured for the test suite in tests/__init__.py. Historically, the enforcement was configured inside the nose-legacy setup_package() hook:

python

# tests/__init__.py
from googleapiclient import _helpers as util
def setup_package():
    """Run on testing package."""
    util.positional_parameters_enforcement = "EXCEPTION"
Because modern test runs in this repository (including via `nox` sessions) run under **`pytest`**, the `setup_package()` package-level hook is ignored. As a result, the tests run in warning-only mode, causing strict parameter assertion tests to be bypassed and fail with an `AssertionError` instead of raising `TypeError`.
Since the repository has migrated to `pytest`, this legacy hook is dead code. We should configure the variable directly at the package module level and completely remove the unused `setup_package` hook:
```diff
# tests/__init__.py
from googleapiclient import _helpers as util
+util.positional_parameters_enforcement = "EXCEPTION"
- def setup_package():
-     """Run on testing package."""
-     util.positional_parameters_enforcement = "EXCEPTION"
#### Stack trace
When running the tests using `pytest`, the test fails with the following output:
