by clicking test button
on the toolbar or
in ActionMenu.
The result of the testing will appear in the TestOutput tab panel
separately for each component. You can choose to combine, view (and
save) all the test results for all subcomponents in one panel
corresponding to their parent. Look at Combine

finished. For longish tests if user needs to see the ongoing results
look at Update runtime test log.

component will pop-up a context menu with a list of tests available for
that object; you can choose one of them. Test result will appear in the
TestOutput tab panel.

Enable
Hardware-OFF - Options menu
By default, dvs_gui does not load hardware objects defined in the
database if their status is marked as OFF. The applications associated with these HW objects
are not loaded either. When the `Enable Hardware-OFF' box is checked the user will
load all HW objects and the diagnostics will be run on all items selected regardless of their ON/OFF state.
Test
level and scope selector - Options menu
Test objects can have different complexity levels. User can select
which tests to execute depending on their complexity level. When this
option menu is triggered, a dialog window is appearing for the user to
choose a different level for the testing session. Tests with higher
level are more complex. All tests up to that given level are executed.
By default test level is set to 0, meaning that minimum number of tests will be executed.
User can filter out execution of some tests, by selecting a test scope.
When this option is triggered, a dialog window appears for the user to
choose a test scope. Only defined scope in the database are presented to the user.
All tests that do not fit this selection will not be executed.
Log
viewer settings - Options menu
User can select one of the proposed settings for the application log:
last log, last but one, last but two, last 2000 lines or the last log
or all logs available for that application.
