A new cmocka release version 1.1.0


It took more than a year but finally Jakub and I released a new version of cmocka today. If you don't know it yet, cmocka is a unit testing framework for C with support for mock objects! We set the version number to 1.1.0 because we have some new features: Support to catch multiple exceptions Support to verify call ordering (for mocking) Support to pass initial data to test cases A will_return_maybe() function for ignoring mock returns Subtests for groups using TAP output Support to write multiple XML output files if you have several groups in a test and improved documentation We have some more features we are working on. I hope it will not take such a long time…

Testing PAM modules and PAM-aware applications in the Matrix


Jakub Hrozek and I are proud to announce the first release of pam_wrapper. This tool allows you to either simplify testing PAM modules or your application using PAM to authenticate users. PAM (Pluggable Authentication Modules) is a layer of abstraction on top of Unix authentication. For testing PAM-aware applications we have written a simple PAM module called pam_matrix. If you plan to test a PAM module you can use the pamtest library we have implemented. It simplifies testing of modules. You can combine it with the cmocka unit testing framework or you can use the provided Python bindings to write tests for your module in Python. Jakub and I have written an article for LWN.net to provide more details how…

Group support for cmocka


Last Friday I've released cmocka 0.4.0. It has several bugfixes and at least two new features. One is support for groups. This means you can define a setup and teardown function for a group of unit tests. I think some people have been waiting for this. You can find an example here. It is simple and easy to use. The other small feature is a new macro: assert_return_code(). It is designed for standard C function return values which return 0 for success and less than 0 to indicate an error with errno set. It will produce a nice error message! The rest are bugfixes and improvements for error message. Thanks to all contributor and bug reporter! If you think cmocka…

Unit testing with mock objects in C


The article Jakub Hrozek and I wrote for Linux Weekly News (LWN.net) about CMocka and using mock objects is available to the public now. You can find it here: Unit testing with mock objects in C cmocka is a unit testing framework for C with support for mock objects. It is used by several Free Software projects like libssh, csync, SSSD or Elasto Cloud. If you don't have a LWN.net subscription you should consider getting one ;)

cmocka – a unit testing framework for C


I'm a big fan of unit testing frameworks. When I developed csync, a bidirectional file synchronizer, I used check to write unit tests from the start. check was ok, but it were running valgrind on your testcases to find memleaks in your code the mode reports were about check. So I needed to add valgrind suppressions to get rid of them. When I started to work on libssh, a library implementing the SSH protocol, I wrote unit tests with check too. libssh is multi platform and also works on Windows and with Visual Studio. So we needed a new unit testing framework which is platform independent and has better code quality. I stumbled upon cmockery, a unit testing framework from…
