A third beta release of Visual Assert is now available for download on www.visualassert.com.
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++.
Around two years ago, in early 2007, after having read about, having tried, and finally having dismissed numerous existing unit testing frameworks for C, I resigned and started thinking about creating a new unit testing framework. Having been accustomed to NUnit and JUnit, I found most frameworks clumsy to use – some “frameworks” like MinUnit are a joke, some frameworks like CUnit require lots of boilerplate code to be written, some frameworks only support C++ but not C, and some manage to combine the worst properties of them all (CppUnit).
cfix 1.2, which has been released today, introduces a number of new features, the most prominent being improved support for C++ and additional execution options.
New C++ API To date, cfix has primarily focussed on C as the programming language to write unit tests in. Although C++ has always been supported, cfix has not made use of the additional capabilities C++ provides. With version 1.2, cfix makes C++ a first class citizen and introduces an additional API that leverages the benefits of C++ and allows writing test cases in a more convenient manner.
cfix 1.1 introduces a number of new features. The most important among these is the additional ability to write kernel mode unit tests, i.e. unit tests that are run in kernel mode. Needless to say, cfix 1.1 still supports user mode unit tests.
All contemporary unit testing frameworks focus on unit testing in user mode. Certainly, the vast majority of testing code can be assumed to be targeting user mode, so this does not come at a surprise.
Despite the fact that mainstream support for Windows 2000 has ended in 2005 and the system is well on its way to retirement, Windows 2000 is still in wide use today. As such, it remains being an important target platform for many software packages.
The fact that cfix has not provided support for Windows 2000 was thus unfortunate – after all, if Windows 2000 is among the target platforms of your software, you should be able to run your tests on this platform.
