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.
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.
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.
A new version of cfix, the unit testing framework for C and C++ on Windows, is now available on Sourceforge. Despite fixing several minor issues, the new version resolves the following two issues that were reported by users: Definiting multiple WinUnit fixtures with setup/teardown routines in a single .cpp file leads to a compilation error A thread handle is leaked during execution of a test (#2889511) Updated binaries and source code are available for download on Sourceforge.
The Beta 2 release of Visual Assert (formerly named cfix studio) is now available for download. The release marks a major step in the development of Visual Assert for that it not only comprises a number of bugfixes but also introduces major new features. The two most important certainly are support for EXE targets and Wizard assistance. Support for EXE Targets As announced in a previous post and also discussed in the post about the cfix 1.
A new version of the cfix unit testing framework is now ready for download. Unlike the previous release, which was mainly a maintenance release, cfix 1.5 adds major new features: kernel mode multithreading and EXE-based unit tests. EXE based unit tests As I discussed in a previous post in the context of Visual Assert/cfix studio, cfix’ restriction to DLL based unit tests has turned out to be quite a limitation for certain kinds of projects.
N.B. cfix studio was the code name of what has become Visual Assert The biggest shortcoming of the current cfix studio version certainly is that it requires all tests be implemented in a DLL. Conceptually, keeping test cases separated from the remaining code certainly is a good idea – and implementing tests in a DLL is a way to accomplish this. However, there are many projects in which such separation is either not feasible or just too much effort.
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).
