I just released the first version of rake-tester, an extension of the
[rake-compiler] gem that allows the testing of Ruby C extension parts
with C testing frameworks, e.g. [cmockery].
This allows you to test the pure-C parts of your Ruby extensions in C.
* Automatic compiling and running of test suites
* Support for running single test suites with valgrind or gdb
* Test suites can only be compiled for the current platform,
not for cross-compile targets (but you couldn't run them on
your machine anyways...)
The project's home is http://www.github.com/karottenreibe/rake-tester
