Is 6.0 backward compatible?

Hi Merrin,

Isolator 6.0 didn't introduce new breaking changes. However, one thing I can think of causing tests to fail is improved errors detection Isolator 6.0 contains.

What happens when the tests fail? Does it throw an exception? Can you post example of the tests that fail?

Below is what I see for a failure. Looks like I need to refactor all unit tests to pass this.

TestCase 'UnitTests.Test_Method'
failed: TypeMock.ArrangeActAssert.NestedCallException :
*** WhenCalled does not support using a property call as an argument.
- To fix this pass null instead of ClassName.PropertyName

***
* Example - this would work:
- MyObj argument = Something.Other().GetStuff();
- Isolate.WhenCalled(() => ObjUnderTest.MethodUnderTest(argument))...;
***
* Example - this would not work:
- Isolate.WhenCalled(() => ObjUnderTest.MethodUnderTest(Something.Other().GetStuff()))...;

The issue you've encountered is what we refer to as "chain within chain" you have a method call inside the method call you set behavior on.

This issue is not new - it's a known limitation we had since the first version OF AAA API.

The error message was added in the last version - but the functionality is the same as previous versions.

I am getting the NestedCallException when calling a static method that doesn't use nested chain calls:

Isolate.WhenCalled( () => ApplicationRecordTransformer.GetLateChargeAssessment( null ) ).WillReturn( "562.00" );

Error Message:
Test method FinanceSource.Core.Models.ServicesTests.Funding.RecordTransformerLeaseTest.TransformApplicationRecord_Should_Generate_Correct_Output_for_US threw exception: TypeMock.ArrangeActAssert.NestedCallException:
*** WhenCalled does not support using a method call as an argument.
- To fix this pass null instead of ApplicationRecordTransformer.GetLateChargeAssessment()

***

- Isolate.WhenCalled(() => ObjUnderTest.MethodUnderTest(argument))...;

Hi,

I couldn't reproduce the error here. Can you please post the code of the test and the relevant code from the method under test? If it's a problem to post the code you can email it to our support. I'll try to reproduce it here, it seems like a bug.
