Comment

public static async IAsyncEnumerable<string> GetTestValues()
{
    yield return "foo";
    yield return "bar";

    await Task.CompletedTask; // to make the compiler warning go away
}

var serviceMock = new Mock<IMyService>();
serviceMock.Setup(s => s.CallSomethingReturningAsyncStream()).Returns(GetTestValues);

var thing = new Thing(serviceMock.Object);
var result = await thing.MyMethodIWantToTest();
Assert.Equal("foo", result[0]);
Assert.Equal("bar", result[1]);
