Handling mechanism</td>

<td class="print-category">Description</td>
<td colspan="5" class="print">It is proposed to add one new features to
the TTCN-3 core language standard that C++ like exception handling
mechanism is supported in core language. Sometimes the errors in
different level can be handled using scripts by users flexibly. This is
realized and proved useful in real testing.<br />
<br />
Here is the example:<br />
<br />
try<br />
{<br />
    [block statment]<br />
}<br />
catch<br />
{<br />
    [block statment]<br />
     var charstring e:= "exception A";<br />
     throw (e);<br />
}<br />

<td class="print-category">Additional Information</td>
<td colspan="5" class="print">1. try...catch... statment only catches
the exception which caused by executor or internal error. The user
defined exception is not supported and transferred.<br />
<br />
2. try...catch gives the control of the execution of test suites to the
users when internal runtime error happens. Most times users did not want
to terminate the automatic execution even if the runtime error happened.
This statment gives them the way.</td>

<td class="print">Regarding CR 2565: The setverdict statement has been
extended already such that a reason or cause for the verdict can be
provided by the user. CR2565 will provide the corresponding extensions
for the TRI such that the reason can also be passed to the TCI-TM.<br />
<br />
So far, STF 349 considers that user-defined exceptions do not extend the
expressiveness of the language. Surely, some cases can be written in a
more simple way. Would it be possible to get some more examples or use
cases showing the benefit of introducing user-defined exceptions. (you
can contact me directly at <a
href="mailto:thomas.deiss@nsn.com">thomas.deiss@nsn.com</a>).<br />
<br />
Catching runtime system errors and continueing test case execution would
to some extend break the philosophy of TTCN-3. Once something went wrong
in the test case - causing a runtime system error - the verdict would
have been set to 'error' and further execution of the test case was
considered meaningless. When catching runtime errors as exceptions, the
verdict should not be set to 'error'.<br />
<br />
These are some initial thoughts by STF 349 on the CR. A more detailed
analysis will be done.</td>
