Templates
For a function template (or a member function of a class template), all instantiations share one counter set. Coverage measured by Testwell CTC++ refers to the common definition in source code, not to separate instantiations in binary code.
Example
The function template max
template <typename T>
T max(T x, T y){
if (x > y){
return x;
}
else {
return y;
}
}
is tested once for a float and once for an int
instantiation with:
float myfloat = max<float>(3.14159, 2.71828); int myint = max<int>(127, 8191);
The coverage result is
