@mgorny can you try annotating the failing tests with @pytest.mark.online and see if the test suite then passes?

[mgorny]

FWIU initializing OSHFixtures.systems_api is failing in global scope, therefore preventing the file from being imported, and possibly some more of the initializations below are going to fail as well. To fix this, I suppose the relevant bits would need to be initialized lazily or otherwise locally, and I'm not really sure how many tests would remain — or if any would.

[mgorny]

As I've suspected, all the *_api variable inits cause Internet accesses, and when I remove all of them, all the tests that aren't skipped — fail.

[geographika]

@mgorny - #952 runs the tests in offline mode (ignoring those that require network access). Do these changes get the test suite to pass on your setup?

[mgorny]

I'm afraid it doesn't. The test collection still fails on calls being made in the global scope. I think there are only two ways to prevent this from happening: either don't issue any network calls in global scope, or modify the pytest collect hook to skip the file entirely when Internet isn't available. I think the former should be easier, and could achieve very similar behavior by moving the class into a session-scope pytest fixture. I can try making a pull request if you'd like.

[geographika]

@mgorny - yes, a pull request would be appreciated. I guess the calls are made before the pytest plugin disables sockets. Attempting to create a GitHub Action and disabling network access did not seem to be a viable option (at least in terms of complexity and maintenance).

[mgorny]

I've opened https://github.com/geographika/OWSLib/pull/1 that modifies your PR to do the fixture approach.

[geographika]

Resolved with #952
