The execution of a performance test has multiple stages.
- Probes and the background tests are started and allowed to initialize
during pre load generation statistics collection
interval.
- Load generation tests are run, if applicable.
- The post load generation statistics collection interval
occurs.
Background tests are started before the
pre load generation
statistics collection interval and stopped after
the
post load generation statistics collection
interval. If there are no load-generating phases (that
is, if there are no load-generating tests in the performance test),
this is the only duration for which the background tests
run. Performance tests automatically stop after running
the load-generating tests (if applicable) and the
post
load generation statistics collection interval.
