<H3>BOOST_CHECK_NO_THROW( statement )</H3>
|
|
<P class="first-line-indented">This tool is used to perform an no throw check. The tool executes 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 this
|
|
tool allows to proceed further with test case in this case.</P>
|
|
<P class="first-line-indented">If check is successful, the tool produces a confirmation message (note:
|
|
to manage what messages appear in the test output stream set the proper log level), in other case
|
|
it produces an error message in a form "error in <test case name>: exception was thrown
|
|
by <statement>.</P>
|
|
<P class="first-line-indented">The only tool's parameter is the statement to execute while checking
|
|
for exception. Use block statement if you want to execute more than one statement.</P>
