[BUG] tests/test_blocking_network.py::test_pycurl* failures due to whitespace (?) #130

Closed mgorny closed 11 months ago

mgorny commented 1 year ago

Describe the bug When running the test suite via tox, I'm getting two test failures:

FAILED tests/test_blocking_network.py::test_pycurl - AssertionError: assert {'errors': 0,...pped': 0, ...} == {'errors': 0,...pped': 0, ...}
FAILED tests/test_blocking_network.py::test_pycurl_with_allowed_hosts - AssertionError: assert {'errors': 0,...pped': 0, ...} == {'errors': 0,...pped': 0, ...}

After adding -vv to the runpytest() method calls, I see that the mismatches seem to be on whitespace:

To Reproduce tox -e py311

Expected behavior Passing tests ;-).

Environment (please complete the following information):

Additional context I suspect this could be due to a different cURL version.

mgorny commented 1 year ago

Hmm, or perhaps it's the httpbin version.

httpbin                   0.10.1
pytest-httpbin            2.0.0

Yeah! I think we need to compare parsed values
