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.
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.
Visual Assert, the unit testing Add-In for Visual Studio/Visual C++ has finally left its beta status and – better yet – is now available for free, both for commercial and non-commercial use. Visual Assert, based on the cfix 1.6 unit testing framework, allows you to easily write, manage, run, and debug your C/C++ unit tests -– without ever leaving the Visual Studio® IDE. No fiddling with command line tools, no complex configuration, and no boilerplate code required.
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 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++.
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.
Back when I began thinking about creating a Visual Studio Add-In for cfix, I needed a code name for the project. After tentatively using the name cfix+ for a while, I quickly settled on cfix studio – given that the project revolved around cfix and Visual Studio, this name pretty much suggested itself. Soon after going into Beta, however, I had to realize that this name was not without its problems.
