Variables (access)

Set
VsUtil­s.v­ari­abl­es[­'­<na­me>­'] = v
Get
v = VsUtil­s.v­ari­abl­es[­'­<na­me>­']
Tip: use <from VsUtils import variables as vs> to access variables easily with <vs['...'­]>

Assertion

assert­True(expr)
assert­False(expr)
assert­Equal(fisrt,second)
assert­Not­Equal(fisrt,second)
assert­Alm­ost­Equal(fisrt,second,places=7)
assert­Not­Alm­ost­Equal(fisrt,second,places=7)
assert­Raises(excClass,callObj, *args,­**k­wargs)
fail()
all assertions with additional parame­ters:
(..., msg=None, contin­ueT­est­=True)
msg could use format string: "...%­i" % vs[...]

Async assertion

assert­Tru­eIn­ter­val­(expr)
assert­Fal­seI­nte­rva­l(expr)
assert­Alm­ost­Equ­alI­nte­rva­l(f­irs­t,s­ec,­places)
assert­Not­Alm­ost­Equ­alI­nte­rva­l(f­irs­t,s­ec,­places)
assert­Tru­eAt­Lea­stI­nte­rva­l(expr)
assert­AtL­eas­tOn­ceT­rue­(expr)
all assertions with additional parame­­ters:
 (..., msg=None)

Async usage 

async = ATLAsyncTest(self)
async.assert...(lambda:vs[*varname*]...,msg)
async.assert...('vs[*varname*]...',msg)
async.assert...(*function*,msg)
async.execute(timeout)
expr and msg could be lamda, string or function
expr should contains only one variable.
expr is evaluated one time to get the variable

Advanced tips

How to disable warning import msg
sys.mo­dul­es[­'­iho­oks­'­].c­urr­ent­_im­por­ter.ad­dOk­Mod­ule­('xxx)
In custom assert, how to get correct file/line
Use tbskip param in self.r­esu­lt.a­dd­Failure
How to interact with operator ?
Use wx python binding

Interact with Logbook 

rtc.setLogLevel(*level*)
rtc.startLogSession('*SessionName*', '*comment*')
rtc.logMessage(RTC.Logger.*level*, '*UserModule*', '*msg*')
...
rtc.stopLogSession()
Levels are: Debug, Info, Warning, Error, Critical

RTC services

Creation
rtc = RTC.RT­CMa­nager(ip [, port])
Connection
rtc.co­nnect(ip [, port])
Configure if not done by mmi
rtc.co­nfi­gure(client name, dbPath)
Usercode control
rtc.[s­tar­t/s­top­]Code(codeName)
Monitoring control
rtc.[s­tar­t/s­top­]Mo­nitor(taskName)
Archiver control
rtc.[s­tar­t/s­top­]Re­cor­dset(rsName)
Manage errors
try:... except: System­Error , detail:

VS callback 

class notifier(Vs.Callback):
    def variableDidChange(*args):
        print 'callback called'
callback = notifier()
notif = VsUtils.vc.
   registerCallbackValueChanged(name,callback)
...
del notif
Callback class should be created outside of register method.
Other callback are available.

Variables (creation)

VsUtil­s.v­c.c­rea­teV­ari­abl­e('<name>', Vs.<type>, [capacity=1])
VsUtil­s.v­c.d­ele­teV­ari­abl­e('<name>')
Types are: INTEGER, DOUBLE, OPAQUE

Tips

import time
time.s­lee­p(s­econds)

Testcase 

class *<TestCase name>*(ATLTestCase):
&nbsp;&nbsp;def initialize(self):
&nbsp;&nbsp;&nbsp;&nbsp;# no exception inside this method
&nbsp;&nbsp;def finalize(self):
&nbsp;&nbsp;&nbsp;&nbsp;# no exception inside this method
&nbsp;&nbsp;def execute(self):
&nbsp;&nbsp;&nbsp;&nbsp;# test steps here, see Assertions
