[Please do not mail me a copy of your followup] boost-users@lists.boost.org spake the secret code <20131222101745.6cff920b@rid> thusly:
Unfortunately the Boost.Test framework only provides a terse message like this:
test.cpp(123): fatal error in "fnTest": exception thrown by test();
It doesn't tell you which exception was thrown, nor the reason why.
The only place I can find this text is in the implementation of BOOST_{WARN,CHECK,REQUIRE}_NO_THROW(). Are you really writing a test about exception handling, or is this a side-effect of your test case? IMO, unless you are exercising the exception handling properties of a piece of code, you shouldn't be using BOOST_xxx_NO_THROW -- any test case will fail if the exercised code throws an exception. So if you are testing normal functionality of the code, then just let the unexpected exception be thrown and the test framework should print an appropriate message. For instance, this code: #include <stdexcept> void foo() { throw std::runtime_error("What the hell?"); } BOOST_AUTO_TEST_CASE(test_foo) { foo(); BOOST_REQUIRE(true); } fails with this output: Running 1 test case... unknown location(0): fatal error in "test_foo": std::runtime_error: What the hell? -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://computergraphicsmuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!
