I know where you are coming from on this point, and I general would agree if it were not for the advantages you get from C++ test framework. Having worked with multiple C and C++ frameworks, I've found that one of the biggest advantages of the C++ frameworks is the amount of boilerplate code they can save you from writing. Also nearly all of C frameworks I've used make use macros to the point that they look more like objective C than C. In general I feel that even if the test code is written in C++ the code itself should be simple enough that someone with even a passing knowledge of C++ could easily understand the intent of the test code. > > Some of the major advantages of google test that I see over continuing to > > use > the > > current test include giving a consist feel to all tests, a powerful test > > execution framework which allow individual test suites or tests to be > > specified > > from the command line, support for a standard xunit output which can be > integrated > > into a continuous build systems, and a very powerful mocking library > > which allows much more control over testing failure conditions. > > It would be interesting to better describe in details what is missing > currently > and what such a framework can bring. > (I agree there is a huge room for improvements on unit tests) Some of the things I've come across include: No standard output format to integrated with continuous regression systems No ability to specify specific unit tests or groups of tests to run from the command line No standard set of test assertions used across the test suites. No standard setup and teardown functions across test suites, state from previous test suite can break current Requirement to use a python script to orchestrate test runs. No support for mocking functionality. I know that none of the above couldn't be fixed in our current test application, but I would question if it is effort worthwhile when we take an off the shelf framework, which does all those things and a whole lot more, which has been test and used in a huge variety of projects. I certainly willing to look at other frameworks both C and C++ but I yet to find a C framework which come close to the usability and flexibility of the popular C++ ones.
