Steps to Reproduce

With Nix:

nix build github:NixOS/nixpkgs/master#python3Packages.opentelemetry-instrumentation-asgi -L --show-trace

Without Nix:

With Python ^3.12 and asgiref ^3.8, run the tests in opentelemetry-instrumentation-asgi.

Expected Result

Tests should pass

Actual Result

Tests are failing

Additional context

No response

Would you like to implement a fix?

None

Thanks for reporting. This looks like a bug in the AsgiTestBase class in core though.

This is not specific to python 3.12.

Not sure it's the right approach but

makes tox -e py310-test-instrumentation-asgi -- -k test_http_repeat_request_headers_in_span_attributes pass

I guess that at least AsgiTestBase should inherit from IsolatedAsyncioTestCase

Before:

python3.12-opentelemetry-instrumentation-asgi> tests/test_asgi_custom_headers.py::TestCustomHeadersEnv::test_http_custom_request_headers_in_span_attributes FAILED [  1%]
python3.12-opentelemetry-instrumentation-asgi> tests/test_asgi_custom_headers.py::TestCustomHeadersEnv::test_http_custom_request_headers_not_in_span_attributes FAILED [  2%]

After applying the two patches:

python3.12-opentelemetry-instrumentation-asgi> tests/test_asgi_custom_headers.py::TestCustomHeadersEnv::test_http_custom_request_headers_in_span_attributes PASSED [  1%]
python3.12-opentelemetry-instrumentation-asgi> tests/test_asgi_custom_headers.py::TestCustomHeadersEnv::test_http_custom_request_headers_not_in_span_attributes PASSED [  2%]

Then the rest of the tests were broken.

Good news is that the updated code works for both asgiref 3.7.2 and 3.8.1
