1053-1085: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winSplit the failure contract from the duplicate-event xfail.
The strict xfail covers the entire sync and async failure tests. If
_assert_one_failurefails on a duplicate event, it exits before checking completion and usage. The xfail also masks a failure in the exception assertion. These tests therefore do not independently protect the exception, no-completion, and usage contracts.This is a test-coverage gap, not a current production failure. Keep separate strict-xfail tests for the failure-event count so
XPASS(strict)still detects the#7783fix.Suggested fix

The strict xfail for crewAIInc#7783 covered the whole sync and async failure tests, so the raise, no-completion and usage assertions never ran for OpenAI. Those now run for both providers, and the failure-event count has its own strict-xfail tests.

Applied the CodeRabbit nitpick in aded568: the strict xfail for #7783 no longer covers the whole sync and async failure tests. The raise, no-completion and usage checks now run unmarked for both providers, and the failure-event count has its own strict-xfail tests, so |

Summary
Adds
lib/crewai/tests/llms/test_tool_stream_usage_contract.py: one shared set of behavioral tests run against both the native OpenAI (Chat Completions) and Anthropic providers through fake SDK responses. No API key, no network, no paid call. Tests only; no source change.What each provider has to do identically:
available_functions, every call comes back in order with its id, name and arguments, sync and async. Withavailable_functions, the function runs once with the parsed arguments and its result is returned. The call completes once, asTOOL_CALL.toolmessage is sent back paired with the id of the call it answers.LLMStreamChunkEvent, in order, sync and async. A streamed tool call is returned like a non-streamed one; its chunk events share one id while the arguments accumulate.get_token_usage_summary()and reports them onLLMCallCompletedEvent.LLMCallFailedEvent, noLLMCallCompletedEvent, and counts no usage; non-streaming, async and streaming.Legitimate provider differences are recorded on the adapters instead of being hidden behind a shared assertion: the shape of a returned tool call (OpenAI SDK objects or dicts with JSON-string arguments, Anthropic tool-use blocks with dict arguments), and where a tool result lives in the request (a
toolmessage for OpenAI, atool_resultblock in a user turn for Anthropic).Defects the tests exposed
Two of the 42 cases fail on current
main. Both are markedxfail(strict=True)against the issue that reports the defect, so the mark has to be removed in the change that fixes it:#7783(already open, not mine): the non-streaming OpenAI handlers emitLLMCallFailedEventandcall()/acall()emit it again. Two cases, which assert only the failure-event count; the raise, no-completion and usage checks for a failed call run unmarked for both providers. I am not submitting a competing fix.A third defect these tests exposed,
#8060(the Anthropic streaming handlers returned tool calls without emittingLLMCallCompletedEvent), was reported first and has since been fixed by #8061. This branch is merged up tomain, the mark for that case is removed, and the case passes.Verification
pytest tests/llms/test_tool_stream_usage_contract.py: 40 passed, 2 xfailed.pytest tests/llms: 922 passed, 20 skipped, 2 xfailed, so the new module does not disturb the provider suites around it.#8060case failed onmainand reportedXPASS(strict)against the fix branch, which shows the test detects the fix.tests/llms/test_multimodal.pydoes.Additional context
Kept standalone so it does not conflict with the milestone 1 and 2 PRs (#8037, #8039). It uses the same adapter-per-provider pattern as #8037, and I will fold the duplicated helpers (
_Recorder, the fake raw response) into the shared fixtures once that lands. Gemini and Bedrock are the next milestone and are not touched here.Prepared with AI assistance (Claude Code), per CONTRIBUTING. I don't have permission to apply the
llm-generatedlabel, so could a maintainer add it?Note
Low Risk
Adds test-only coverage with mocked providers; no runtime or API behavior changes.
Overview
Adds
test_tool_stream_usage_contract.py, a new shared pytest suite (issue #8006, milestone 3) that exercises native OpenAI and Anthropic LLM providers through mocked SDK responses—no API keys or network.The same scenarios run for both providers via
_OpenAIContract/_AnthropicContractadapters: tool calls (return shape,available_functions, tool-result pairing), streaming (text chunks, streamed tool args,LLMStreamChunkEvent), token usage onget_token_usage_summary()andLLMCallCompletedEvent, and failures (raise, singleLLMCallFailedEvent, no completion/usage). Provider-specific request/response shapes are asserted on the adapters, not hidden behind one generic check.Two OpenAI cases are
xfail(strict=True)for #7783 (duplicate failure events on non-streamingcall/acall). Anthropic cases skip when the Anthropic SDK is missing. Production code is unchanged—tests only.Reviewed by Cursor Bugbot for commit 3057303. Bugbot is set up for automated code reviews on this repo. Configure here.
