SYNOPSIS
|
||||
--------
|
||||
[verse]
|
||||
'perf test <options>'
|
||||
'perf test [<options>] [{list <test-name-fragment>|[<test-name-fragments>|<test-numbers>]}]'
|
||||
|
||||
DESCRIPTION
|
||||
-----------
|
||||
This command does assorted sanity tests, initially through linked routines but
|
||||
also will look for a directory with more tests in the form of scripts.
|
||||
|
||||
To get a list of available tests use 'perf test list', specifying a test name
|
||||
fragment will show all tests that have it.
|
||||
|
||||
To run just specific tests, inform test name fragments or the numbers obtained
|
||||
from 'perf test list'.
