cfix studio Beta 2 to add support for EXE-based unit tests

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.

Introducing cfix studio, the Visual Studio AddIn for C/C++ Unit Testing

Posted on

N.B. cfix studio was the code name of what has become Visual Assert There is little doubt that native code, and C and C++ in particular, is here to stay. And still, it is pretty obvious that when it comes to tools and IDEs, it is the managed world that has gotten most attention from tool vendors over the past years. While there are lots and lots of useful tools for native development, many of them probably even better than their managed counterparts, there are some areas where the managed language fraction is far ahead: One of these areas certainly is IDE support for unit testing.

cfix 1.4 released

Posted on

Today, a new version of cfix, the open source unit testing framework for user and kernel mode C and C++, has been released. cfix 1.4, in addition to the existing feature of allowing test runs to be restricted to specific fixtures, now also allows single testcases to be run in isolation, which can be a great aid in debugging. Besides several minor fixes, the cfix API has been slightly enhanced and cfix now degrades more gracefully in case of dbghelp-issues.

cfix 1.3.0 Released, Introducing WinUnit Compatibility

cfix 1.3, the latest version of the unit testing framework for C/C++ on Windows, has just been released. As announced in the last blog post, the major new feature of this release is WinUnit compatibility, i.e. the ability to recompile existing WinUnit test suites into cfix test suites without having to change a single line of code. To demonstrate that this compatibility indeed works, consider the following simple example:

Embracing WinUnit

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).

Working Around TlbImp's Cleverness

TlbImp, the .Net tool to create Interop assemblies from COM type libraries, contains an optimization that presumably aims at making the consumption of the Interop assembly easier, but ultimately is a nuisance. Consider the following IDL code: import "oaidl.idl"; import "ocidl.idl"; [ uuid( a657ef35-fea1-40ad-86d8-bb7b6085a0a3 ), version( 1.0 ) ] library Test { [ object, uuid( 84b2f017-b8fe-4c2c-87b8-0587b4bf5507 ), version( 1.0 ), oleautomation ] interface IFoo : IUnknown { HRESULT Foo(); } [ object, uuid( 13d950d6-beb3-4dd3-957b-88b0e5eb5e3f ), version( 1.

cfix 1.2 Installer Fixed for AMD64

The cfix 1.2 package as released last week contained a rather stupid bug that the new build, 1.2.0.3244, now fixes: the amd64 binaries cfix64.exe and cfixkr64.sys were wrongly installed as cfix32.exe and cfixkr32.sys, respectively. Not only did this stand in contrast to what the documenation stated, it also resulted in cfix being unable to load the cfixkr driver on AMD64 platforms. The new MSI package is now available for download on Sourceforge.

cfix 1.2 introduces improved C++ support

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 1.1.1 released

As discussed last week, cfix 1.1.0 has suffered from a potential deadlocking issue when run in the VisualStudio 2008 debugger. cfix 1.1.1 mitigates this problem and should now work equally well with Visual Studio 2005 and 2008. When run in a debugger, cfix now will not try to capture a stack trace for a failed assertion any more. These stack traces usually have been redundant to what the debugger provides, yet the logic to implement this has been the reason for the interference with the VS 2008 debugger.

cfix 1.1 goes LGPL

cfix 1.0 had been licensed under the GNU General Public License. One of the characteristics of the GPL is that it disallows proprietary binaries to be linked against GPL-licensed binaries. In the context of cfix, linking is quite a concern – after all, every test-DLL has to be linked against cfix.dll. As cfix.dll is GPL-licensed, this means that it would be illegal to redistribute the test-DLL, along with the cfix test runner, commercially.
