Inserting a synchronization point enables you to coordinate the
activities of a number of virtual users by pausing and resuming activities.
You can synchronize all virtual users at the beginning of a test and stagger
the release times so that the users do not overload the system. Synchronization
points are also useful in stress testing.
About this task
You can insert a synchronization point into a schedule or a test.
You typically insert synchronization points into schedules, because they are
more visible at the schedule level and you can set the
Release and
Timeout options
within a schedule only, not within a test. However, you should insert a synchronization
point into a test in the following cases:
- You want to control where the synchronization point appears. For example,
you can insert a synchronization point just before a test sends a request
to a server.
- You have edited a test, and the execution of a synchronization point depends
on the logic that you have added.
Synchronization points within loops are not reset.
In other words, once a synchronization point has been released (in the first
iteration of a loop) it stays released for all further iterations.
