Customizing the module's initialization function

In this usage variant, you do not define macro BOOST_TEST_MODULE and instead provide the definition of function init_unit_test. This is going to be the custom initialization function. The default test runner will use it to initialize the test module.

Example: using custom initialization function

Code

#define BOOST_TEST_ALTERNATIVE_INIT_API
#include <boost/test/included/unit_test.hpp>
#include <iostream>

BOOST_AUTO_TEST_CASE(test1)
{
  BOOST_TEST(false);
}

bool init_unit_test()
{
  std::cout << "using custom init" << std::endl;
  return true;
}

Output

> custom_init
using custom init
Running 1 test case...
test.cpp(7): error: in "test1": check false has failed

*** 1 failure is detected in the test module "Master Test Suite"
[Note] Note

Because we overwrote the default initialization function, it does no longer assign any name to the master test suite. Therefore the default name ("Master Test Suite") is used.

For reporting errors that may occur during the initialization,

An error reported in this function aborts the execution of the test module.

[Note] Note

The reason for defining BOOST_TEST_ALTERNATIVE_INIT_API is described here.
