Scheduling an NQA Test Group
By configuring NQA test group scheduling, you can set the start time and test duration for a test group
to perform NQA tests. The start time can take a specific value or can be now, which indicates that a
test is started immediately; the test duration can take a specific value or can be forever, which
indicates that a test does not stop until you use the undo nqa schedule command to stop the test.
A test group performs tests when the system time is between the start time and the end time (the start
time plus test duration). If the system time is behind the start time when you execute the nqa
schedule command, a test is started when the system time reaches the start time. If the system time
is between the start time and the end time, a test is started at once. If the system time is ahead of the
end time, no test is started. To view the current system time, use the display clock command.
