Orleans.FSharp.Testing

Test utilities for Orleans.FSharp grains -- in-process clusters, mocks, property-based testing, and log capture.

Components

TestHarness

Wraps an Orleans TestCluster with memory storage, memory streams, and integrated log capture. Start and tear down a full in-process silo in a few lines:

let! harness = TestHarness.createTestCluster ()
let grain = harness.Client.GetGrain<IMyGrain>(grainId)
// ... test grain calls ...
do! harness.Cluster.StopAllSilosAsync()

GrainMock

A MockGrainFactory that implements IGrainFactory with predefined grain responses. Useful for unit testing grain-to-grain interactions without a real silo:

let factory = MockGrainFactory()
GrainMock.withGrain<IMyDep> "key" myMockImpl factory

GrainArbitrary

TypeShape-based auto-generator of FsCheck Arbitrary instances for F# discriminated unions. Automatically discovers DU cases and field types to produce well-typed random grain states.

FsCheckHelpers

  • commandSequenceArb<'Command> -- generates non-empty command sequences
  • stateMachineProperty -- verifies a state invariant holds after folding a command list

LogCapture

CapturingLogger / CapturingLoggerFactory -- an in-memory ILogger implementation that records structured log entries (CapturedLogEntry) for test assertions on log level, template, properties, and exceptions.

Dependencies

  • Microsoft.Orleans.TestingHost
  • FsCheck 3.x
  • TypeShape
  • xunit
