Details

The Function template class is designed to test any arbitrary C or C++ function (not member methods, just regular functions).The following is an example that tests open() for various error conditions.

#include <sapi/test.hpp>
//because open() has variable arguments we wrap it to make it work with thisclass int test_open(const char * path, int o_flags, int o_mode){ returnopen(path, o_flags, o_mode);}
bool is_test_enabled = true;
Test::initilize("test name", "0.1");
if( is_test_enabled ){  //when test is constructed  Function<int, const char *, int, int> open_function_test("open",test_open);
  open_function_test.execute("NO EXIST Read only", -1, ENOENT,"/home/non-existing-file.txt", O_RDONLY, 0); open_function_test.execute("NOEXIST Read Write", -1, ENOENT, "/home/non-existing-file.txt", O_RDWR, 0);  open_function_test.execute("NO EXIST Read Write", -1, ENAMETOOLONG,"/home/non-existing-file-too-long-too-long-too-long-too-long-too-long-too-long-too-long-too-long-too-long-too-long.txt",O_RDWR, 0);
