bpo-41939: do not skip test_site.test_license_exists_at_url for pre-releases by ned-deily · Pull Request #22688 · python/cpython
This test is skipped for pre-releases because the license file URL in Lib/site.py used to be to a release-dependent URL. But bpo-21572 changed Lib/site.py to use a license URL that is independent of the release. So there is no longer a reason to skip the test for pre-releases and, by no longer skipping, we would catch problems like the one in this issue prior to release.
