I just installed it onto desktop, loaded Visual Studio 2019 (Ent) and i see no visual reference or otherwise to JustMock.

Honestly If i had have spent the $$ by now i'd have uninstalled and given up.

The CallMethod of the PrivateAccessor is using reflection to invoke the required method. When an exception is thrown inside that method it will be wrapped by the reflection in a TargetInvocationException which is received in the test method.

Instead of the TargetInvocationException, throw the original exception.

Values from already mocked methods are not taken into account when initializing a static constructor from the Telerik.JustMock.PrivateAccessor class.

Here is an example: PrivateAccessor.ForType(typeof(Foo)).SetField("someStringField", "stringvalue");

A workaround is to call the: Mock.Intercept(typeof(Foo)); before calling the PrivateAccessor.

There is a different behaviour when mocking the same method using the following two Arrange overrides:

public static FuncExpectation<TResult> Arrange<TResult>(Expression<Func<TResult>> expression);
public static FuncExpectation<TResult> Arrange<T, TResult>(T obj, Func<T, TResult> func);

Repro project attached. Steps to reproduce:
1. Open attached solution
2. In Tests.cs, run JustMockArrangeQueryableTest - it passes
3. Run JustMockArrangeQueryableTest2 - it fails with a invalid cast exception on the Residents collection.

Hi I have encountered what I think is a bug.

I would expected the following unit test to pass. It does not.

The example is distilled from a more complex case.

Is it not supported to have other threads create mocks?

[Fact]
public async Task Fails()
{
    var iTask = Task.Run(() => Mock.Create<I>());
    var i = await iTask;
    EA expectedArgs = new EA();
    EA receivedArgs = null;
    i.Done += (sender, ea) => receivedArgs = ea;

    i.Raise(x => x.Done += null, expectedArgs);

    Assert.Equal(expectedArgs, receivedArgs);
}

public class EA : EventArgs
{
}

public interface I
{
    event EventHandler<EA> Done;
}
