I'm new to JustMock and Unit Testing in general.

I have a method WriteToDisk(object param) that creates a new FileStream, calls FileStream.Write, then sets a bool property in the class to true. I'd like to test that the property is set to true (if no exceptions are thrown) without actually writing to disk.

I'm just not sure how to arrange things in my test to bypass the Filestream instance and the call to FileStream.Write. Can this even be done with JM?

Hi,

I have been using Justmock for years now without any problem. But lately we started running as our normal users and not as local administrators on our PC's.

When installing Justmock I'm using an elevated admin account and it seems to complete without any errors, afterwards I'm starting VS19 as my normal user and are presented with the dialog shown in the attached file.

The log shows that the assembly could not be found or loaded, when looking in the folder specified in the error, I do not have an <extensions> folder at the location. So I assume that installing the product with my administrator access does not work for my normal user, what to do? 

The activity log shows the following error:

Hello!

I have an interesting problem I am trying to solve unit testing Sitecore. I have wrapped myController to get to a dynamic accessor and I am getting an exception way down in the mscorplib System.DefaultBinder. Looking for leads on what I am missing on my setup?

Exception: 

System.ArgumentException: Array may not be empty.
Parameter name: match

 

Code:

    var controllerAccessor = Mock.NonPublic.Wrap(_myController);

 

    Mock.NonPublic.Arrange<IMyParameters>(controllerAccessor.GetRenderingParameters<IMyParameters>()).Returns(_myParameters);

 

Stack trace:

Is there a way to mock non virtual public/protected methods? I see it's possible for private but not for protected and public.

In a couple of my tests, I want to prove that the calling code can handle a null being returned, but whenever I tell the Returns method to return null, I get an instance of the returned type.

How can I mock an interface with default implementations? The following test fails:

Was looking for ways to pull the lambda expressions I mock up....this way I could reuse them during the assertion portion of my test.

However when I pass the value in via a variable I get a test exception:
Telerik.JustMock.Core.MockException: The arranged function is not set up to return a value of type Account


Here is a sanitized version of what I'm trying to do?


public Interface IAccountManagement{
   public Account GetAccount(string acctId);
}
........

public void MyTest()
{
   IAccountManagement actMgrMock = Mock.Create<IAccountManagement>();
   Account acct = TestHelpers.AutoGenerateAccount;  //generate an acct object with Ploeh.AutoFixture

   Expression<Action> GetAccount = () => actMgrMock.GetAccount(Arg.IsAny<string>());

  //Mock.Arrange(GetAccount).Returns(e);   //<------this call will not work when I invoke the test?

  Mock.Arrange(() => actMgrMock.GetAccount(Arg.IsAny<string>())).Returns(e); //  This one works?

  // invoke
  
  //Assert
  //Mock.Assert(GetAccount,Occurs.Once());

}
  

Both Azure Storage Emulator and JustMock use port 10001 and 10002 as default ports.

Is it possible to change the ports JustMock uses?

My solution has 3000+ unit tests and suddenly, 1000+ tests failed with the error :

 Message:

They pass in debug, but not in run.

I try to clear bin and obj folder of my solution, but nothing to do.

Any idea ?

Hi,

I'm using JustMock to mock SharePoint objects in some Unit Tests. When I run Unit Tests (I use ReSharper as test runner) and the JustMock profiler is enabled, the unit tests are much slower. Normally, one Unit test runs within seconds. With the JustMock profiler enabled, I have to wait several minutes. Is there something I can do to accelerate this?

 

Thank you very much!
