Check exception messages using GoogleTest

Question

Is it possible to check the message generated by the exception? Currently, you can do:

ASSERT_THROW(statement, exception_type) 

which is all good and good, but no where can I find a way to check e.what () is really what I'm looking for. Is this impossible to do with the Google test?

Something like the following will work. Just catch the exception somehow, and then do EXPECT_STREQ on calling what() :

 #include "gtest/gtest.h" #include <exception> class myexception: public std::exception { virtual const char* what() const throw() { return "My exception happened"; } } myex; TEST(except, what) { try { throw myex; } catch (std::exception& ex) { EXPECT_STREQ("My exception happened", ex.what()); } } int main(int argc, char **argv) { ::testing::InitGoogleTest(&argc, argv); return RUN_ALL_TESTS(); }
