Writing test cases

This recipe and the next one are devoted to auto-testing using the Boost.Test library, which is used by many Boost libraries. Let's get hands-on with it and write some tests for our own class:

#include <stdexcept> 
struct foo { 
    int val_; 
 
    operator int() const; 
    bool is_not_null() const; 
    void throws() const; // throws(std::logic_error) 
}; 

Getting ready

Basic knowledge of C++ is required for this recipe. To compile code of this recipe, define BOOST_TEST_DYN_LINK macro and link against the boost_unit_test_framework and boost_system libraries.
