Hi Team

We tried executing justMock test cases in command prompt using justMock Console (licensed), dotCover and xUnit, but justMock Test execution failed and gave the error "System.InvalidProgramException : Common Language Runtime detected an invalid program." 

The command we use to execute is as follows:

start /wait "" "{PATH}\JustMock\Libraries\Telerik.JustMock.Configuration.exe" /link "dotCover"

"{PATH}\JustMock\Libraries\Telerik.JustMock.Console.exe" runadvanced --profiler-path-64 "{PATH}\JustMock\Libraries\CodeWeaver\64\Telerik.CodeWeaver.Profiler.dll" --command "{PATH}\JetBrains.dotCover.CommandLineTools.2021.1.3\dotCover.exe" --command-args "cover --reporttype=html --output=CodeCoverage\\index.html --targetexecutable=\"{PATH}\xunit.runner.console.2.4.1\tools\net472\xunit.console.exe\" -- \"{PATH}\{PATH_OF_JUSTMOCK_TEST_DLL}\""

start /wait "" "{PATH}\JustMock\Libraries\Telerik.JustMock.Configuration.exe" /unlink "dotCover"

 

Attaching the log and test code.

Hi

I have a function:

    Public Function UpdatePasswordHistory(ByVal mods As DataSource, ByVal StaffCode As String, ByVal Password As String) As Integer


        Dim strSQl As New StringBuilder("Insert into [dbo].[PasswordHistory]([StaffCode],[Password],[DateSet])")
        strSQl.Append($"values('{StaffCode}','{EncryptPassword(UCase(Password))}','{System.DateTime.Today.ToString("yyyy-MM-dd")}')")


        Return mods.SqlDB.ExecuteNonQuery(strSQl.ToString())

    End Function

 

I want to create 2 tests.

The staffcode is a foreign key so must exists.

If no issues it should return 1. else 0.

My 2 tests always return 0.

I probably done this all wrong

   public void UpdatePasswordHistory_Staffcodeexists()
        {
            // Arrange
      var mockDS = Mock.Create<DataSource>();
            clsSecurity clsSecurity = Mock.Create<clsSecurity>();

            string Staffcode = "sahmed";
            string password = "test";
            Int32 rowsaffetced = 1;
            Int32 actualRowsaffected;

            Mock.Arrange(() => clsSecurity.UpdatePasswordHistory(mockDS, Staffcode, password)).Returns(rowsaffetced);

            actualRowsaffected = new clsSecurity().UpdatePasswordHistory(mockDS, Staffcode, password);

            Assert.AreEqual(rowsaffetced,actualRowsaffected);
        }

        [TestMethod]
        public void UpdatePasswordHistory_Staffcodedoesnotexist()
        {
            // Arrange
            var mockDS = Mock.Create<DataSource>();
            clsSecurity clsSecurity = Mock.Create<clsSecurity>();

            string Staffcode = "InvalidUser";
            string password = "test";
            Int32 rowsaffetced = 0;
            Int32 actualRowsaffected;

            Mock.Arrange(() => clsSecurity.UpdatePasswordHistory(mockDS, Staffcode, password)).Returns(rowsaffetced);

            actualRowsaffected = new clsSecurity().UpdatePasswordHistory(mockDS, Staffcode, password);

            Assert.AreEqual(rowsaffetced, actualRowsaffected);
        }

Over the weekend Visual Studio was upgraded to 16.10.0 on our self-hosted Azure DevOps agent server. This has caused all of our unit tests that rely on the JustMock profiler to begin failing with the Exception:

Failed {METHODNAME} [6 ms]
  Error Message:
   Test method {NAMESPACE}.{CLASSNAME}.{METHODNAME} threw exception: 
System.InvalidProgramException: Common Language Runtime detected an invalid program.
  Stack Trace:
      at {NAMESPACE}.{CLASSNAME}.{METHODNAME}()
   at System.Runtime.CompilerServices.AsyncMethodBuilderCore.Start[TStateMachine](TStateMachine& stateMachine)
   at {NAMESPACE}.{CLASSNAME}.{METHODNAME}()

We are using JustMock R2 2021, the Telerik JustMock VSTest v.2 (v2.6.1) pipeline task, and our test projects are targeting netcore3.1.

The tests run and pass when executed locally through Visual Studio (16.10.0) Test Explorer, but fail during pipeline execution. Nothing else has changed on the agent server except for the Visual Studio upgrade that I am aware of.

I am new to JustMock, I try to use it in .NET5 but failed, I have seen some articles related to this kind of problem but I failed to resolve it. At the same time, I use MOQ for this project, I have tried TypeMock before but have already uninstalled.

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:

690 ERROR CreateInstance failed for package [JustMockPackage]Source: 'mscorlib' Description: Filen eller assemblyen 'file:///c:\users\foobar\appdata\local\microsoft\visualstudio\16.0_4cd0081b\extensions\alz4b0wd.jii\Telerik.JustMock.VS2017.dll' eller en af dens afhængigheder kunne ikke indlæses.

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:

etc etc

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.

So for example lets says I have a method signature like:

public interface ExampleInterface
{
IList<IBob> GetMeAllTheBobs(ISomeParameter someParameter)
}

When I mock like so:

var stubExampleClass = Mock.Create<IExampleClass>();
Mock.Arrange(() => stubExampleClass.GetMeAllThyeBobs(Arg.Any<ISomeParameter>()).Returns(null);

I will get an instance of IList<IBob> back instead of null.

Any suggestions?

Visual Studio Professional 2019 16.6.5
JustMock 2020.2.616.1
.Net Core 3.1

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

using Telerik.JustMock;
using Xunit;
 
namespace XUnitTestProject1
{
    public interface IMyInterface
    {
        bool SomeCheck() => false;
    }
 
    public class UnitTest1
    {
        [Fact]
        public void Test1()
        {
            var mock = Mock.Create<IMyInterface>();
            Mock.Arrange(() => mock.SomeCheck()).Returns(true);
 
            Assert.True(mock.SomeCheck());
        }
    }
}
