Hello, I tried to write a test suite with one expected failure, however it is not working. Probably I'm doing something wrong. The idea is that I have a function that can be implemented in few ways, thus there are few possible correct results. Depending on the implementation, I want to test it with different set of test cases. I don't want to check at the beginning of each test case which option is valid, I would prefer to skip unnecessary test cases. Is it possible? The simplified code is below: bool xxx = ...; // opt1 and opt2: two exclusive options // one of them always passes and one always fails void opt1(){ BOOST_CHECK(xxx); } void opt2(){ BOOST_CHECK(!xxx); } void test1_1(){ } test_suite* init_unit_test_suite( int argc, char* argv[] ) { test_case* opt1_case = BOOST_TEST_CASE(&opt1); test_case* opt2_case = BOOST_TEST_CASE(&opt2); test_suite* dichotomic_test = BOOST_TEST_SUITE( "dichotomic test" ); framework::master_test_suite().add(dichotomic_test); dichotomic_test->add( opt1_case ); dichotomic_test->add( opt2_case ); // I want exactly one of them to fail dichotomic_test->increase_exp_fail(1); test_case* case1_1 = BOOST_TEST_CASE(&test1_1); case1_1->depends_on(opt1_case); framework::master_test_suite().add(case1_1); } I'll be thankful for help, Maria
