Hi folks, I ported a sample of my tests from C to the Perl framework. Want to share my experiences. Good: 1) AFAICS technically you could do all the things you could do in C - working with structures, using callback functions, using threads. Existing problems probably can be ironed out. 2) additional processing of the test results can be done easier and quicker than in C Bad: 1) constants must be explicitely declared or plain numbers used instead 2) no documentation on the framework yet. 3) in many cases data sizes must be specified manually - for structures processing, function parameters. 4) more difficult to track issues. than in C Note, issues (1) and (2) probably can be fixed. Summary: For this application C is higher-level language than Perl, provides more services to developer. After trying the Perl framewok I still vote for using C for the unit tests. For more information about advantages C over Perl see my previous messages. Note, with David Elliott improvements of MigGW toolchain it is now possible to use one more set of Win32 headers under *nix. Differences between header files can be found without using Windows. I urge you to try to use the framework and share your experience. The sample Alexandre sent earlier helped me a lot. I attached my script.
