The third optional parameter - `timeout` - defines the timeout value for the test unit. As of now the __UTF__
isn't able to set a timeout for the test suite execution, so this parameter makes sense only for test case
registration. By default no timeout is set. See the method
-[memberref boost::unit_test::test_suite::add] for more details about the timeout value.
+[memberref boost::unit_test::test_suite::add] for more details about the timeout value.
To register group of test units in one function call, the [classref boost::unit_test::test_suite `test_suite`] class provides another
[memberref boost::unit_test::test_suite::add `add`] interface covered in the advanced section of this documentation.
