unit test in boost

I have the following code for my unit test:

BOOST_AUTO_TEST_CASE (test_adapter) {
  boost::random::mt19937 gen;
  boost::normal_distribution<> nd1(10.0,31.0);
  unsigned int imax = 1000;
  std::vector<double> x, x_p;
  for (unsigned int k = 0 ; k < 1000 ; k++) {
    std::vector<double>().swap(x);
    std::vector<double>().swap(x_p);
    for (unsigned int i = 0 ; i < imax ; i++) {
      x.push_back(nd1(gen));
      x_p.push_back(nd1(gen));
        }
   }
        log_rtns <double >lr;
        BOOST_CHECK(lr( x, x_p) == false );

}

and this is my log_rtns:

template<class T>
class log_rtns: public std::binary_function<T,T,bool> {
 public:
  inline bool operator()(T t, T t_p) {return (std::log(t/t_p));}
};

You are creating a log_rtns variable (here log_rtns lr;) without specifying the template parameter T. So you have to write log_rtns<something> lr;.

I would guess you want log_rtns<double>, but the lr variable is not used.

Also you can't call BOOST_CHECK_CLOSE() on two arrays. You have to do something like

BOOST_CHECK_EQUAL(x.size(), x_p.size());
for (size_t i = 0; i < x.size(); ++i) {
    BOOST_CHECK_CLOSE(x[i], x_p[i], 0.00000000000);
}
