Hello Rhys,

What did you mean "BOOST_FIXTURE_TEST_SUITE per [1]"?

I created test application:

#define BOOST_TEST_MODULE test

#include <boost/test/unit_test.hpp>
#include <iostream>

class Fixture
{
public:
Fixture()
{
std::cout << "Long time initialization" << std::endl;
}
};

BOOST_FIXTURE_TEST_SUITE( default_engine, Fixture )

BOOST_AUTO_TEST_CASE( test_1 )
{
}
BOOST_AUTO_TEST_CASE( test_2 )
{
}

BOOST_AUTO_TEST_SUITE_END()

Below is output:

Running 2 test cases...
Entering test suite "test_application"
Entering test suite "default_engine"
Entering test suite "inner_suite"
Entering test case "test_1"
Long time initialization
Test case test_1 did not check any assertions
Leaving test case "test_1"
Entering test case "test_2"
Long time initialization
Test case test_2 did not check any assertions
Leaving test case "test_2"
Leaving test suite "inner_suite"
Leaving test suite "default_engine"
Leaving test suite "test_application"

As you can see "Long time initialization" string appears twice.
