Check (unit testing framework)

Check is an open source unit testing framework in the style of xUnit for C programs. The framework is considered stable—even though it has not reached its 1.0 release yet—and is available in the package distribution systems of most Linux distributions, as well as for Windows and OS X.

Check is used by some well-known projects such as GStreamer.

Example of Check unit test

Test writing using Check is very simple. The file in which the checks are defined must include check.h as so:

#include <check.h>
// The basic unit test looks as follows:
 	
START_TEST (test_name)
{
  /* unit test code */
}
END_TEST
// The START_TEST/END_TEST pair are macros that setup basic structures to permit testing. 
// It is a mistake to leave off the END_TEST marker; doing so produces all sorts of strange errors when the check is compiled.
