How to test MFC applications using Visual Assert or cfix

Automated testing of GUI applications is tricky. It is not only tricky because testing the GUI itself is hard (despite there being good tools around), it is also tricky because GUI applications often tend to be a bit hostile towards unit testing. One class of GUI applications for which this kind of hostility often applies is MFC applications. Although MFC allows the use of DLLs, components, etc, the framework still encourages the use of relatively monolithic architectures.

Visual Assert 1.1 beta and cfix 1.7 released

Posted on

Slightly delayed, Visual Assert 1.1 beta is now available for download. As announced in a previous post, the most important change in the new version is added suport for the latest version of Visual Studio, Visual Studio 2010. However, the new version also brings a couple of new features that apply to all versions of Visual Studio. Most importantly, cfix and Visual Assert now expose an API that allows developers to plug in custom event sinks.

Coming soon: Visual Assert for Visual Studio 2010

Now that Visual Studio 2010 has oficially been released, I keep getting questions about a Visual Studio 2010-enabled version of Visual Assert. The fact that Visual Studio 2010 is already out, yet there is no Visual Assert version for it is unfortunate. It would have been nice to have Visual Studio 2010 support ready on Visual Studio’s release date, however, that was not possible due to lack of time. Having solved most compatibilty issues though (of which there were many, Visual Studio 2010 is a truly painful release for AddIn developers), I am now confident to be able to offer a first beta by begin of May.

cfix 1.6 released, simplifies authoring of multi-threaded tests

A new release of cfix, the unit testing framework for C and C++, is now available for download. Besides some minor enhancements like extending the maximum permitted fixture name, cfix 1.6 introduces a major new feature, Anonymous Thread Auto-Registration. Since its very first release, cfix has supported multi-threaded test cases, i.e. test cases that spawn child threads, each of which potentially making use of the various assertion statements like CFIX_ASSERT. To make this work and ensure that failing assertions are handled properly, however, usage of CfixCreateThread (rather than the native Win32 CreateThread) was mandatory when spawning such threads.

How to customize test run execution to make your cfix test runs more effective

One of the features introduced back in cfix 1.2 was the ability to customize test execution with the command line parameters -fsr and -fsf. Using these switches can make your test runs more effective and can help simplify debugging – so it is worth spending a minute on this topic. Assume our test run comprises two fixtures, Fixture A and Fixture B. As fixtures are always run in alphabetic order, and tests run in the order they are defined, the first test to be executed is Test 1 of Fixture A, followed by Test 2 of Fixture A, and so on.

Along with JUnit, JWebUnit, NUnit, and SimpleTest, cfix was one of the nominees for the Automated Testing Institute’s Automation Honors Award 2009 in the category Best Open Source Unit Automated Test Tool. A few days ago, the results were published and cfix finished second – surpassed only by JUnit, which finished 1st (No real surprise here). If you are interested, there is a video in which the results are presented.

Visual Assert, in case you have not tried it yet, is an Add-In for Visual Studio that adds unit testing capabilities to the Visual C++ IDE: Based on the cfix unit testing framework, Visual Assert allows unit tests to be written, run, and debugged from within the IDE. Pretty much like Junit/Eclipse, TestDriven.Net or MSTest, but for real, native code – code written in C or C++.

LTCG issues with the WIN7/amd64 environment of WDK 7600

Now that Windows 7 is out, we all sooner or later have to upgrade to WDK 7600. I am still reluctant to move away from WDK 6000⁄6001 because of the dropped W2K support, but this is a different issue. However, as one cfix user who has obviously already adopted WDK 7600 kindly pointed out to me, linking a kernel mode unit test against cfix using WDK 7600 and the WIN7/amd64 environment fails reproducibly with the following error message:
