I am excited to present to you the R1 2020 release of our mocking framework JustMock which includes improvements to the Azure Pipeline task, new integration with Visual Studio code coverage for .NET Core and implementation of ArrangeSet and AssertSet methods to the MockingContainer.
Without further ado let me introduce you the new features and most important fixes.
We know your pains and we are addressing them. The execution of JustMock unit tests targeting .NET Core in Azure pipeline had a different approach than those targeting the .NET Framework. With this release, we are unifying how the tests for both platforms are executed and now you can use only the JustMock task to execute your tests without other additional tasks, tooling or settings. The new version of the extension is already uploaded and the task will be automatically updated in your pipeline. If you would like to try it here is the link to the marketplace..
Another pain you wrote us frequently about is the lack of support for Visual Studio 2019 test platform. With this release we are providing this option for you. In addition to that we have fixed an issue with failing tests when the “Installed by Tools Installer” option is selected for test platform version. With this we have implemented and fixed all known issues and requests related to the test platform version.
Many of our clients are using Visual Studio Enterprise and they love the build in code coverage. Actually, this is the tool that JustMock is most frequently integrated with. However, there was a limitation. The integration could be used only for projects targeting .NET Framework. With this new release we are introducing support for projects targeting .NET Core as well.
Until now it was difficult and additional efforts were required to arrange and assert the set operation of a property when you used our implementation of an IoC container named MockingContainer. This is why we implemented the ArrangeSet and AssertSet method for the MockingContainer. The API is now similar to the one for mocking normal property set operation.
var container =
secondDep => secondDep.GetString()).MustBeCalled();
thirdDep => thirdDep.IntValue = Arg.AnyInt).MustBeCalled();
var actualString = container.Instance.StringMethod();
container.AssertSet<IThirdDependency>(thirdDep => thirdDep.IntValue = 10);
This issue was very unpleasant. While debugging the code you have mocked in a .NET Core project the debugger arrowhead pointer was at a different line of the code than the actual one. After thorough research of what is causing the issue, we found out that the underlining problem is a bug in the .NET Core CLR. Long story short, Microsoft provided a fix to this bug. If you would like to take advantage of this fix you could upgrade your application to .NET Core 3.1 version, which includes the fix.
