Boost Test Error: main already defined

I have a Visual Studio project where I want to do some unit tests with Boost.Test.

And I have 2 files:

File 1:

#define BOOST_TEST_MODULE FileX

#include <boost/test/unit_test.hpp>
#include <stdio.h>

BOOST_AUTO_TEST_SUITE(test_suite_name)

BOOST_AUTO_TEST_CASE(TestFileX)
{
    BOOST_CHECK(true);
}


BOOST_AUTO_TEST_SUITE_END()

And File 2:

#define BOOST_TEST_MODULE XContainer

#include <boost/test/unit_test.hpp>
#include <stdio.h>

BOOST_AUTO_TEST_SUITE(test_suite_name2)

BOOST_AUTO_TEST_CASE(TestXContainer)
{
    BOOST_CHECK(true);
}

BOOST_AUTO_TEST_SUITE_END()

When I compile the project I get a link error that's saying that main is already defined. I noticed that main file is defined in unit_test.hpp but I need to include it for the test macros.

How should I add 2 test cases in 2 separate file?

Solution

  • You must use #define BOOST_TEST_DYN_LINK in every source file with tests.
