In Visual Studio 2022, the first quick action is often "Create Mock". As this is used in the overlay when hovering over a method, I see "JMA001" quite often, which is not helpful when writing non-test code.

I know that I could create a .editorconfig file to suppress individual hints for every project I work on, but how can I prevent the JustMock hints from being used in the quick actions completely across projects?

I'm working on tests for legacy code that instantiates a ServiceController (in System.ServiceProcess) to check for a running SQL Server instance. I want to add the tests to our CI/CD build pipeline, so I decided to use JustMock to future-mock ServiceController since the service in question will not exist on the build server. These tests are all using xUnit.

However, the test (which has 3 variants specified via xUnit's InlineData attributes) started hanging on the first variant. It's not just long-running; I've let it run for hours (it's normally a 3-second test at most), and CPU usage is negligible. ServiceController is IDisposable, so I figured it might have something to do with that.

After a lot of paring down, I can repro the problem with the following code in a new project:

public class JustMockTest
{
    [Theory]
    [InlineData("test")]
    public void TestMethod(string whatever)
    {
        Mock.Arrange(() => new ServiceController()).DoNothing();
    }
}

However, this test (in the same class) works fine and completes in about 1s - note that it's a fact, not a theory:

[Fact]
public void TestMethod2()
{
    Mock.Arrange(() => new ServiceController()).DoNothing();
}

This is JustMock v2022.1.223.1, xUnit v2.4.1.0, and VS 2022.

At first I wondered if my 3 variants were somehow stepping on each other's Mock.Arrange() statements; but as you can see, the top test, while declared as a theory, only has 1 variant and still has the problem. What's also interesting is that an analogous setup for MSTest also runs fine - so this seems to be xUnit-specific somehow:

[TestClass]
public class UnitTest1
{
    [DataTestMethod]
    [DataRow("test")]
    [DataRow("test2")]
    public void TestMethod1(string whatever)
    {
        Mock.Arrange(() => new ServiceController()).DoNothing();
    }
}

At first I thought IDisposable classes may be the problem, but it seems it's actually MarshalByRefObject; it's a base class of ServiceController and others I can repro with (WebClient, MemoryStream, etc.), and I can also repro by mocking a simple class of my own that extends MarshalByRefObject.

Is this a known issue? Are there recommended workarounds (without having to ditch xUnit for MSTest or another framework)?

Thanks!

Hi,

I am trying to run to  Dotnet Test command for .NetCore dll in Azure Devops and It throws exception for some tests saying elevated Mocking Exception.

Comand Used is

I want the Mock to return the SQL statement and Not execute the statement. This is what i have done but it keeps running the "connection.execution(SQL)".  

string SQL = "";

            Mock.Arrange(() => connection.Execute(Arg.AnyString, null, null, null, null)).DoInstead((string arg1) => { SQL = arg1; }).IgnoreInstance().Returns(1);



            WebApiProject.Controllers.DeleteController dc = new WebApiProject.Controllers.DeleteController();
           
            dc.Post(mockedDeleteObject);

            Assert.IsTrue(SQL == $"DELETE FROM TEST WHERE 1=1");

Post{

                string SQL;
                SQL = $"delete from {TableName}  where  {WhereClause} ";

                con.Execute(SQL,parameters );}

But it keeps running the sql executable statement

Hi,

I am getting intermittent errors when running the above Test. It fails so infrequently that I am unable to debug. When it fails, here is what I see in the logs.

Unfortunately my JustMock does not work anymore. I get this exception:

Some background:

- I started of with VS2019 version 16.10.4 and JustMock version 2019.2.620.1

- Profiler is enabled in Extensions->JustMock

- tried to reinstall -> no effect

- upgraded VS2019 to 16.11.9 -> no effect

- upgraded to JustMock 2022.1.119.1 -> no effect

- Above is just a sample, all of my unit tests that use JustMock fail

- I checked a colleague and he had exactly the same problem

Any setting/config I might have missed?

Regards,

Dirk

Hi,

I'm getting the following error for a blazor project using MSTest2 using JustMock flite.

}

A bit puzzled as to why the error references xunit.

Hi, 

Please let me know on how do we mock  a private constructor.

Example:

 public class Sum
    {
        public int GetSum()
        {
            return SumBy2.Add1(10,5);
        }


        public int GetSum2()
        {
            SumBy1 by1 = new SumBy1();
            return by1.Add(10, 5);
        }


        private class SumBy1
        {
            public int Add(int a, int b)
            {
                return a + b;
            }
        }

        private static class SumBy2
        {
            public static int Add1(int a, int b)
            {
                return a + b;
            }
        }
    }

Need to create Unit tests for Sum class.
