LCORE-2119: Implement Integration Tests for Custom Spans - #2638
Conversation
Adds integration-test coverage verifying that request handlers emit their custom OpenTelemetry spans with the expected names, attributes, and events, running against an in-memory span exporter. Signed-off-by: Anik Bhattacharjee <anbhatta@redhat.com>
WalkthroughThe change adds reusable OpenTelemetry span assertions, refreshes tracers for additional integration modules, and adds integration coverage for query, Responses API, feedback, and authorized handlers. ChangesOpenTelemetry span coverage
Priority: ⬇️ Low Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to This change adds OpenTelemetry integration coverage, but the feedback test can leave shared storage configuration pointing at a temporary directory, which may make later tests fail depending on execution order. 🚥 Pre-merge checks | ✅ 7✅ Passed checks (7 passed)
✨ Finishing Touches🧪 Generate unit tests (beta)

@radofuchs @asimurka @tisnik fyi I've reduced the scope from what's written in the JIRA ticket and made these tests representative, not comprehensive. This intentionally does not cover every endpoint that emits a custom span.
Remaining endpoints (conversations, mcp, stream-interrupt, streaming_query, If we do decide we want exhaustive coverage, I'd argue for assigning 1 point for integration tests for each endpoints, such that a total workload of ~18 endpoints represents the amount of work that'll be needed to write, (but more importantly) review all the tests |

Learning: In the lightspeed-stack repository, docstrings must use the section header name "Parameters:" (not "Args:") for function arguments, even if the project references Google Python docstring conventions. Ensure docstrings follow the project’s established "Parameters:" header format for any documented function parameters.

Use the Parameters: docstring header. Both new files document arguments under Args:. This repository requires the Parameters: section header for documented function parameters.

Restore feedback_storage after the test.
This test mutates the shared configuration object. Use monkeypatch.setattr so the temporary path is restored after the test.
