User Reviews

  • It seems like this application is great for testing, but there are some issues that are preventing a better review. First is that most of the binary packages are missing a header file to get a test working. The package is available in the src package. The instructions for building the source also don't appear to work. I am wondering if something minor is missing.

  • I compared a lot of free unit test frameworks. an important point was that the test should continue after an illegal memory operation has been commited. most of the frame works died or became unpredictable even if they detected the segfault. cgreen and libu did the best job. since cgreen has additional mocking features, this one became my favorite.

  • Thumbs up! will try to contribute
