c++ - how to catch exception in cppunit -

we use cppunit test our test framework

the tests organized in test fixtures (inherited cppunit_ns::testfixture)

there new requirement - flush out application buffer @ end of test if has failed.

i can in overloaded teardown() function in test fixture. how know if test has failed.

the result of test checked using cppunit_assert.

there around 12 test fixtures each fixture having around 10 tests. how achieve minimal code change?

i think depends bit on how call tests first idea use testlistener , react testlistener::addfailure call.

note teardown can in theory throw exception (possibly through cppunit_assert) call testlistener::addfailure.

if not work obvious ugly solution set flag @ end of each test method signals test finished , call code when flag not set.
