How Synchronization Points Work

288
Chapter 10 - Designing Performance Testing Suites
To insert a synchronization point into a suite:
s
Click
Suite > Insert > Synchronization Point
.
Note:
For detailed procedures, see the TestManager Help.
For example, when you run a stress test (an attempt to run your applications under
extreme conditions to see if they or the server "break"), your suite might contain
virtual testers that perform the certain operations continuously and repeatedly for
hours on end. To most effectively run a stress test, you could synchronize the virtual
testers so that they perform the operations at the same time to stress the system. You
could do this by inserting a synchronization point to coordinate these virtual testers to
perform certain functions simultaneously.
How Synchronization Points Work
At the start of a test, all virtual testers begin executing their assigned test scripts. They
continue to run until they reach the synchronization point. When specified in a test
script, a synchronization point is a programmatic command (
sync_point
in a VU test
script,
SQASyncPointWait
in an SQABasic test script,
TSSSync.SyncPoint
in a VB
test script, or
TSSSync.syncPoint
in a Java test script). When specified in a suite, a
synchronization point is placed similarly to other suite elements (delays, transactors,
and so on).
