Uniform Session Testing

NuGet Package: NServiceBus.UniformSession.Testing (2.x)
Target Version: NServiceBus 7.x

Shows the usage of the NServiceBus.UniformSession.Testing package.

Prerequisites for uniform session testing functionality

The approach shown here works with the NServiceBus.UniformSession NuGet package version 2.2.0 or above. Install the NServiceBus.UniformSession.Testing NuGet package.

Testing services

Construct the service under test with an instance of TestableUniformSession. Call the methods being tested and make assertions about the messages sent and published.

var session = new TestableUniformSession();
var service = new SomeService(session);

service.DoTheThing();

Assert.AreEqual(1, session.SentMessages.Length);

Testing a handler

Construct the handler under test with an instance of TestableUniformSession.

var session = new TestableUniformSession();
var sharedComponent = new SharedComponent(session);
var handler = new SomeMessageHandler(sharedComponent);

Test.Handler(handler)
    .WithUniformSession(session)
    .ExpectPublish<SomeEvent>()
    .OnMessage<SomeMessage>();

Testing a saga

Construct the saga under test with an instance of TestableUniformSession.

var session = new TestableUniformSession();
var saga = new SomeSaga(session);
Test.Saga(saga)
    .WithUniformSession(session)
    .ExpectPublish<SomeEvent>()
    .WhenHandling<SomeCommand>();
