Assert that an expression does not throw any exception.

Used in: A test function body, the constructor or destructor of a fixture, or a function called from them. See TEST(name, ...).

Requirement: expr; can be used as a complete statement.

The assertion succeeds if, and only if, the statement expr; does not throw any exception.

On success the test function continues without side effects.

On failure the test is terminated with an error report. The report includes the exact expression text and, if the exception inherits from std::exception the string from the virtual member function std::exception::what(), or a generic message otherwise.

Example: The test program

     
     #include <crpcut.hpp>
     
     class type {};
     
     TEST(assert_no_throw_succeeds)
     {
       int n = 0;
       ASSERT_NO_THROW(n+=3);
     }
     
     TEST(assert_no_throw_fails)
     {
       ASSERT_NO_THROW(throw type());
     }
     
     int main(int argc, char *argv[])
     {
       return crpcut::run(argc, argv);
     }

      

reports one failed test:
