Understanding unit testing in Orleans

In this section, we will see how to do unit testing on Orleans grains and ensure they are working fine. Orleans has a NuGet package called Microsoft.Orleans.TestingHost, which can be used to create an in-memory cluster with two silos by default to test your grains. Let's now, step by step, create the unit test project and add tests to test the Grains output.
