Isolator(.Net) evaluation version integration with Xunit

Hello!

Thank you for evaluating and posting!

This exception can be thrown for numerous reasons.
Can you please post your test code here, so we can try and reproduce the problem?

You can also send it to support at typemock.com.

Thanks Yonatan for the quick response. We have created the following method for testing:
----------------------------------
public class MyClass
{
[Isolated]
[Fact]
public void SimpleTestUsingMessageBox()
{
// Arrange
Isolate.WhenCalled(() => MessageBox.Show(string.Empty)).WillReturn(DialogResult.OK);

// Act
MessageBox.Show("This is a message");

// Assert
Isolate.Verify.WasCalledWithExactArguments(() => MessageBox.Show("This is a message"));
}
}
------------------------------------------------------

The above method is giving the following exception

ClassLibrary.Test.MyClass.SimpleTestUsingMessageBox : TypeMock.TypeMockException :
*** No method calls found in recording block. Please check:
* Are you trying to fake a field instead of a property?
* Are you are trying to fake an unsupported mscorlib type? See supported types here: https://www.typemock.com/mscorlib-types

Also, we are trying the below code which is also not running as expected.

-----------------------------------------------------------------
public class MyClassDoSth
{
[Isolated]
[Fact]
public void DoSomething_Call_Success()
{
// Expectations
using (RecordExpectations expect = RecorderManager.StartRecording())
{
MyClassDoSth cls = new MyClassDoSth();
cls.DoSomething("monday", 2);
cls.DoSomething("tuesday", 42);
expect.CheckArguments();

}
MyClassDoSth newClass = new MyClassDoSth();
newClass.DoSomething("saturday", 16); // any parameters
newClass.DoSomething("tuesday", 42); // matching parameters

// Verify
MockManager.Verify();

}
public void DoSomething(string param1, int param2)
{
throw new Exception("Hello from DoSomething!");
}

public MyClassDoSth()
{
throw new Exception("Hello from constructor!");
}
}
Following exception occurred:
---------------------------------------------

Also confirm us that the Isolator(TypeMock) can work with xUnit GUI and Command line interface.
Kindly help us regarding the above.
Thanks

Hi,

These are two different issues...

The AAA code:
The test passes here, with XUnit - perhaps your test project is called TypemockSomething? if so, it is a known issue - please change the project name to something that does not start with Typemock.

The Natural API code:
You are faking the test class itself - write the code under test in a separate class (as you normally wouldn't write production code in your test clsas) and the test will pass.

You should be able to run test using XUnit and Isolator.

Have fun, and feel free to post here or contact our support mail if you are facing any more issues...

Thanks Yonatan.

We have the following production class:
public class Class1
{
public static int GetValue(int a, int b)
{
return a + b;
}
}

We are testing the above method ‘Class1.GetValue’ using the following test class:

public class TestXUnit
{
[Fact]
public void GetValue_Test()
{
// Arrange
Isolate.WhenCalled(() => Class1.GetValue(1,2)).WillReturn(3);

// Act
int v = Class1.GetValue(1, 2);

// Assert
Assert.Equal(3, v);
}
}


During testing, we are getting the following exception:
------------------------------------------------------------------------------------------

TestProject1.TestXUnit.SimpleTestUsingMessageBox2 : TypeMock.TypeMockException :

We are not using ‘Typemock’ in the project Name.
We request you to kindly get us the sample prototype demonstrating .Net Isolator usage with xunit.

Thanks

The error you are getting happens if Isolator is not enabled properly. In your situation, running an external GUI runner, in order to set up the Isolator environment you should run the GUI runner through the supplied TMockRunner.exe. You can find out more about TMockRunner here: http://docs.typemock.com/Isolator/##typemock.chm/Documentation/TMockRunner.html.

In your case it should be something like:

TMockRunner.exe xunit.exe

Hope this helps - please let us know!

We are able to test properly. Thanks very much for all your guidance and support.
