<P class="first-line-indented">These tools are used to perform a "no throw"

check. Tool execute the supplied statement and check that it does not

throw any exceptions. Error would be reported by the framework even if test

statement appear directly in test case body and throw any exception. But

these tools allow to proceed further with test case in case of failure.</P>
