6. Verification Script Engine Output Context members

All verification scripts have output contexts –special structures whose members are set by the

script and can be used inside of the application ( For more details about output contexts – please refer

to the CATC Script Language(CSL) Manual ). The verification script output contexts have only one

member:

out.Result - the result of the whole verification program defined in the verification script.

This member is supposed to have 3 values:

_VERIFICATION_PROGRESS,( is set by default when script starts running )

_VERIFICATION_PASSED,

_VERIFICATION_FAILED

The last two values should be set if you decide that recorded trace does ( or not ) satisfy the

imposed verification conditions. In both cases the verification script will stop running.

If you don't specify any of those values - the result of script execution will be set as

VERIFICATION_FAILED at exit.

7. Verification Script Engine events

VSE defines a large group of trace “events” – packets or special notifications – that can be

passed to a verification script for evaluation or retrieving and displaying some contained information.

The information about the type of event can be seen in in.TraceEvent. Please refer to the topic

“Sending functions” in this manual for details about how to send events to scripts.

7.1 Packet events.

The table below shows current list of packet events and value of in.TraceEvent:

Packet in.TraceEvent

TS1 _PKT_TS1

TS2 _PKT_TS2

Link Packet _PKT_LINK

MAD packets _PKT_MAD

Reliable Connection packets _PKT_RC

Reliable Datagram packets _PKT_RD

Unreliable Connection packets _PKT_UC

Unreliable Datagram packets _PKT_UD
