Different behaviour for different Arrange() overrides

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.

JustMock Profiler causes application hang on "new ReportDocument()"

I am using Visual Studio 2015, Crystal Reports 12.0.2. When running from Visual Studio in debug mode or not, the application hangs on the statement "new ReportDocument()". ReportDocument is a class defined in CrystalReports.

When I disabled the JustMock Profiler, this statement no longer hung.

Just FYI. Hopefully others will see this.

Add integration with CodeRush

Visual Studio Team Services integration

Our team is moving to VSTS and not having an official solution to run JustMock tests through their build system is a deal-breaker.

Allow simple mocking of fluent interfaces

If I define a fluent API, I might have an interface such as this:

public interface IRegistrar {

IRegistrar UsingThis(object someThing);

IRegistrar UsingThat<TThatThing>() }

If I create a mock of this using the default Behaviour.RecursiveLoose and make no arrangements, calls to the methods will return new mocks of the type, rather than the same instance that was called.

It would be nice to have a behaviour type that can return the same instance (in this case the mocked instance) without having to define a stub for each method call.

My code under test might look like:

IRegistrar reg;


.UsingThis(new object())


Currently, a test on the second call will fail if written against the mock assigned to 'reg'.

AssemblyInitialize Mock.SetupStatic

I have logging class which are using everywhere.
I want to Mock this class for all tests. And i tried to use AssemblyInitialize but got problem. I have simulated this problem with JustMock.ElevatedExamples.AdvancedUsage examples:
1) Add BaseTest class
public class BaseTest
public static void AssemblyInit(TestContext context)
Mock.SetupStatic(typeof(Common1), StaticConstructor.Mocked);
// Arranging: When the static(Foo.FooProp_GET) property is called, it should return expected.
var fakeUsed = Mock.Create<LogWriter1>(Constructor.Mocked);
Mock.Arrange(() => Common1.Log).Returns(fakeUsed);

public static void Cleanup()
//clean up stuff here
public static class Common1
static Common1()

Log = new LogWriter1();


public static LogWriter1 Log { get; set; }


public class LogWriter1


2) When run test from VS - all ok
3) When run from command line it is not working. Show Message box "Process Starts Now".

SET COR_PROFILER={B7ABE522-A68F-44F2-925B-81E7488E9EC0}
"C:\Program Files (x86)\Telerik\JustMock\Libraries\JustMockRunner.exe" "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\MSTest.exe" /testcontainer:"D:\test\CSExamples\JustMock.ElevatedExamples\bin\Debug\JustMock.ElevatedExamples.dll"

How i can mock logger for all test? It is static public property.

I use MS Test + VS 2015.

Support for named parameters in Mock.Arrange

It would be good if we could use named parameters inside Mock.Arrange method.

Exception when mocking three or more layers deep with CreateLike<>

When using Mock.CreateLike<> we've found that trying to directly mock anything lower than two layers down on a concrete class (e.g. x => x.Layer1.Layer2.Property == "test") throws a NullReferenceException unless the profiler is enabled. It wasn't clear in the exception or the documentation relating to this method that the real issue was the profiler being disabled, and only by trial and error did we find the solution.
