Do we need "# pants: no-infer-dep" if we import pytest in all test codes

[kamioka-masaya]

Describe the bug
After upgrading from 2.12.0 to 2.14.0 and running the test, the following warning logs were output in large quantities.

04:16:15.25 [WARN] Pants cannot infer owners for the following imports in the target src/python/xxx.py:hoge:

  * pytest (line: 6)

If you do not expect an import to be inferrable, add `# pants: no-infer-dep` to the import line. Otherwise, see https://www.pantsbuild.org/v2.14/docs/troubleshooting#import-errors-and-missing-dependencies for common problems.

Pants version
2.14.0

OS
MacOS, Linux

In Pants 2.14.x the default for https://www.pantsbuild.org/docs/reference-python-infer#unowned_dependency_behavior changed to warning.

The issue is at it's core #12449, but you have a few options:

• Add pytest to your default resolve's requirements (and try and keep the versions the same)
• Downgrade that option back to ignore
• Ignore the warning
