Re: Boost unittest

saneman a ?crit :


It is something specific to many compiled languages: you have only one
entry point of execution (i.e. main() in C++) and code get executed from
there only. The only exception in C++ being the construction of globals
for initialisation. In all cases code is executed from within a function.

Concerning your question:
  1. if you need only one value in your global, you can use:
      std::vector<int> v(1,22);//vector of size one filled with 22
  2. For unit test, usual practice is to set up the environement before
the test such that tests are independant.

Example:

std::vector<int> v;
void init_v(std::vector<int> & vec)
{
  vec.clear();
  vec.push_back(22);
}

BOOST_AUTO_TEST_CASE(test_one)
{
     //init
     init_v(v);

     //test
     int t = *v.begin()
     BOOST_CHECK_EQUAL(t,22);
}

Make v a local variable is even better.
