Why don't you post specific problems with faling test modules examples.

My problem is easy. I want to have one main test that add Second and so on. I cannot get it to work :/ What's the best practice? Is BOOST_CLASS_TEST_CASE a good approach on Second?

I use similar test cases. Please note that my code is probably not perfect as I use for example manuel test registration and still need to adapt the code (using some autotools determined macros) to avoid the static/shared library fiasco but it works at least with older Boost code

I must say you are comming a bit strong here, don't you think? The fact that you were using unsupported configuration which doesn't work anymore is IMO minor inconvinience.

The following code is extracted from my project and mainly uses the fact that one can add test suites as well as simple test functions to other test suites. So it's easy to create hierarchies. I think I once just tried it and it worked. Not sure whether it can be found in the old or new documentation.

/******************************************************/ // test.cpp #include

using boost::unit_test::test_suite;

test_suite* Jacobi_test_suite(); test_suite* GaussSeidel_test_suite();

test_suite* init_unit_test_suite(int, char *[]) { test_suite *test = BOOST_TEST_SUITE("Master test suite"); BOOST_MESSAGE("solver tests"); test->add(Jacobi_test_suite()); test->add(GaussSeidel_test_suite());

return test; }

All you need in this file is #define BOOST_TEST_MAIN #include

/******************************************************/ // Jacobi_test.cpp

#include "../Jacobi.h"

#include #include #include <stdexcept>

using boost::unit_test::test_suite;

void JacobiTest1() { DenseMatrix A(2, 3); Vektor x(3, 1.0); Vektor y(2, 1.0); Jacobi jacobi; BOOST_CHECK_THROW(jacobi.solve(A, x, y), std::logic_error); }

test_suite* Jacobi_test_suite() { test_suite *test = BOOST_TEST_SUITE("Jacobi iteration test suite"); BOOST_MESSAGE("Jacobi tests"); test->add(BOOST_TEST_CASE(&JacobiTest1));

return test; }

This file may look like this: #include "../Jacobi.h" #include #include <stdexcept> BOOST_AUTO_TEST_SUITE( Jacobi_iteration_test_suite ) BOOST_AUTO_TEST_CASE( JacobiTest1 ) { DenseMatrix A(2, 3); Vektor x(3, 1.0); Vektor y(2, 1.0); Jacobi jacobi; BOOST_CHECK_THROW(jacobi.solve(A, x, y), std::logic_error); } BOOST_AUTO_TEST_SUITE_END()

/******************************************************/ // GaussSeidel_test.cpp

#include "../GaussSeidel.h"

#include #include #include <stdexcept>

using boost::unit_test::test_suite;

void GaussSeidelTest4() { DenseMatrix A(3, 3); Vektor x(3); Vektor y(3); GaussSeidel gs1("damped Gau?-Seidel (SOR)", 0.5, 1); // 1 iteration gs1.solve(A, x ,y); BOOST_CHECK_CLOSE(X[0], -108.0/240, 1E-10); BOOST_CHECK_CLOSE(X[1], -27.0/240, 1E-10); BOOST_CHECK_CLOSE(X[2], 38.0/240, 1E-10); }

test_suite* GaussSeidel_test_suite() { test_suite *test = BOOST_TEST_SUITE("Gau?-Seidel iteration test suite"); BOOST_MESSAGE("Gau?-Seidel tests"); test->add(BOOST_TEST_CASE(&GaussSeidelTest4)); return test; }

This file may look like this: #include "../GaussSeidel.h" #include #include BOOST_AUTO_TEST_SUITE( Gau?_Seidel_iteration_test_suite ) BOOST_AUTO_TEST_CASE( GaussSeidelTest4 ) { DenseMatrix A(3, 3); Vektor x(3); Vektor y(3); GaussSeidel gs1("damped Gau?-Seidel (SOR)", 0.5, 1); // 1 iteration gs1.solve(A, x ,y); BOOST_CHECK_CLOSE(X[0], -108.0/240, 1E-10); BOOST_CHECK_CLOSE(X[1], -27.0/240, 1E-10); BOOST_CHECK_CLOSE(X[2], 38.0/240, 1E-10); } BOOST_AUTO_TEST_SUITE_END() Don't you think this look a bit neater? And it works both with static and shared library. All you need is to define BOOST_TEST_DYN_LINK in makefile during compilation to be able to link with shared library. And this works for both *nix and NT. Gennadiy

Gennadiy, Jans example was exactly what I was looking for. It's a nice example how to build many-files suites. Maybe include that in your example pages.

It's up to you, but I would give automated registration a try. Gennadiy
