Hi,
it doesn't work for me. I tried the following code:
/// Generate automatically the 'main' function for the test module
#define BOOST_TEST_DYN_LINK
#define BOOST_TEST_MODULE mpi_test
#include
#include <iostream>
#include "mpi.h"
struct MPIFixture
{
MPIFixture()
{
std::cout << "Global fixture constructor:" << std::endl;
int argc = boost::unit_test::framework::master_test_suite().argc;
char** argv = boost::unit_test::framework::master_test_suite().argv;
MPI_Init(&argc,&argv);
int is_initialized;
int is_finalized;
MPI_Initialized(&is_initialized);
MPI_Finalized(&is_finalized);
std::cout << "MPI environment is initialized: " << is_initialized <<
std::endl;
std::cout << "MPI environment is finalized: " << is_finalized <<
std::endl;
}
~MPIFixture()
{
std::cout << "Global fixture destructor" << std::endl;
int is_initialized;
int is_finalized;
MPI_Initialized(&is_initialized);
MPI_Finalized(&is_finalized);
std::cout << "MPI environment is initialized: " << is_initialized <<
std::endl;
std::cout << "MPI environment is finalized: " << is_finalized <<
std::endl;
MPI_Finalize();
MPI_Initialized(&is_initialized);
MPI_Finalized(&is_finalized);
std::cout << "MPI environment is initialized: " << is_initialized <<
std::endl;
std::cout << "MPI environment is finalized: " << is_finalized <<
std::endl;
}
};
struct MyTestSuiteFixture { };
BOOST_GLOBAL_FIXTURE( MPIFixture )
BOOST_FIXTURE_TEST_SUITE( MyTestSuite, MyTestSuiteFixture )
BOOST_AUTO_TEST_CASE( dummy_test )
{
std::cout << "Running dummy test case" << std::endl;
}
BOOST_AUTO_TEST_SUITE_END()
The output when running with mpirun:
Global fixture constructor:
MPI environment is initialized: 1
MPI environment is finalized: 0
Running 1 test case...
Running dummy test case
Global fixture destructor
MPI environment is initialized: 1
MPI environment is finalized: 0
MPI environment is initialized: 1
MPI environment is finalized: 1
Output when running directly the executable:
Global fixture constructor:
MPI environment is initialized: 1
MPI environment is finalized: 0
Running 1 test case...
Running dummy test case
Global fixture destructor
MPI environment is initialized: 1
MPI environment is finalized: 0
Segmentation fault (core dumped)
I'm using boost 1.55.0 and gcc 4.8.2 on linux.
Best regards,
Martin Vymazal

A global fixture seems like a more appropriate solution than implementing
main().
BOOST_GLOBAL_FIXTURE
Indeed. Something like the following works just fine:
struct MPIFixture {
MPIFixture() { MPI_Init(NULL, NULL); }
~MPIFixture() { MPI_Finalize(); }
};
BOOST_GLOBAL_FIXTURE(MPIFixture);
