Crate runifold_provider_testkit 

Offline HTTP cassette and fault-injection support for provider adapters.

The server intentionally speaks HTTP/1.1 over a loopback socket. This keeps provider tests independent from a production HTTP stack while still exercising real request serialization, response streaming, delays, and mid-stream disconnects.

Structs

BenchmarkFailureCount

Count of failures in one normalized category.

BenchmarkInvocation

Result and host-observed timing for one invocation.

BenchmarkPlan

Bounded benchmark execution plan.

BenchmarkRegressionComparison

Complete baseline-to-candidate benchmark decision.

BenchmarkRegressionMetric

One comparable benchmark metric and its gate decision.

BenchmarkRegressionPolicy

Allowed degradation from a baseline report.

CassetteServer

A loopback server executing a fixed sequence of HTTP exchanges.

ErrorContract

Expected classification of a failed provider invocation.

HttpExchange

One expected request and its scripted response.

LatencyDistribution

Latency distribution expressed in integer microseconds.

ModelBenchmarkTarget

Canonical Runifold model adapter for BenchmarkTarget.

ObservedRequest

A request captured by the cassette server.

ProviderBenchmarkReport

Stable, serialization-safe benchmark evidence.

ProviderConformanceReport

Evidence produced by a conformance run.

ResponseChunk

One response body fragment and the delay before it is sent.

ScriptedResponse

A streamed HTTP response, optionally disconnected before its terminator.

ServerStats

Snapshot of cassette-server concurrency and completion counters.

SuccessContract

Expected canonical result of a successful provider invocation.

Enums

BenchmarkFailureKind

Stable framework-neutral failure category.

BenchmarkInvocationError

Invalid timing evidence supplied by a benchmark adapter.

CassetteError

Errors produced by cassette construction, serving, or verification.

ConformanceCheck

One successfully verified provider behavior.

ProviderBenchmarkError

Benchmark construction or comparison failure.

ProviderConformanceError

A provider violated its canonical acceptance contract.

Traits

BenchmarkTarget

Framework-neutral operation executed by the benchmark runner.

Functions

benchmark

Runs warmup and measured invocations against one framework-neutral target.

compare_benchmarks

Compares two reports using one explicit regression policy.

verify_error

Executes and verifies one failed canonical provider invocation.

verify_success

Executes and verifies one successful canonical provider invocation.

Type Aliases

BenchmarkFuture

A boxed benchmark invocation future.
