TipsAndTricks

For a simple (and free!) way of calculating test coverage with C and C++ programs, have a look at gcov, the GNU test coverage program: http://gcc.gnu.org/onlinedocs/gcc-3.0/gcc_8.html

The return value from the test program is the number of test failures - i.e. if all the tests pass, the program will return 0; if three tests fail, the program will return 3; etc. This can be handy in makefiles, scripts, etc.

You can use global variables in your tests/suites:

#include "tests.h"



START_SUITE(mySuite)



MyVariable *var;



START_TEST("myTest")

   ... lots of tests, one which sets var ...

END_TEST("myTest")



START_TEST("printVar")

   var->print();

END_TEST()



delete(var);



END_SUITE()
