Module test_utils 

Available on crate feature test-utils only.

Test utilities for deterministic completion-model tests.

Modules

streaming_conformanceNot (target_os=unknown and WebAssembly)

Wire-sequence conformance scenarios for provider streaming pipelines.

Structs

AppendFailingMemory

Memory backend that loads empty history and always fails on append.

CapturedHttpRequest

Request data captured by RecordingHttpClient.

CountingMemory

Memory backend that records load and append calls while delegating storage to InMemoryConversationMemory.

FailingMemory

Memory backend that always fails on load and no-ops append and clear.

HttpErrorStreamingClient

An HttpClientExt implementation whose send_streaming fails immediately with a non-success HTTP status and response body.

MockCompletionModel

A cloneable scripted CompletionModel for tests.

MockEmbeddingModel

A deterministic EmbeddingModel that returns a fixed vector for each input document.

MockModelLister

A ModelLister that returns a preconfigured list of models.

MockMultiTextDocument

A test document that contributes multiple text fragments to an embedding request.

MockStreamingClient

A mock HTTP client that returns pre-built SSE bytes from send_streaming.

MockTextDocument

A test document that contributes one text fragment to an embedding request.

MockTurn

A scripted non-streaming mock completion turn.

RecordingHttpClient

An HttpClientExt implementation that records unary requests and returns a fixed response.

SequencedHttpClient

An HttpClientExt implementation that records unary requests and returns one scripted response per request.

SequencedStreamingHttpClient

An HttpClientExt implementation that returns one scripted stream of byte chunks from send_streaming.

Enums

MockError

Scripted error returned by MockCompletionModel.

MockHttpResponse

Response scripted for RecordingHttpClient.

MockStreamEvent

Scripted streaming event yielded by MockCompletionModel.

Constants

MOCK_PROVIDER

Provider descriptor name reported by the test doubles.

Functions

mock_final

Build the terminal record the mock model yields, carrying usage.

mock_final_with_total_tokens

Build a terminal record whose usage has only total_tokens set.

scoped_tracing_subscriber_guard

Serializes tests that install scoped tracing subscribers (tracing::subscriber::set_default / with_default).

scoped_tracing_subscriber_guard_blocking

Blocking variant of scoped_tracing_subscriber_guard for synchronous tests.
