Wait until op(function(*args), value) is True or until timeout

expires

• timeout how long the function will try the function
• retry_interval how long to wait between retries
• func the function that will be executed
• value the value to be compared against (defaults to True)
• op the comparison function (defaults to equality) * args optional arguments to be passed to func when called

Returns the return value of the function If the operation times out then the return value of the the function is in the 'function_value' attribute of the raised exception.

e.g.

try:
   # wait a maximum of 10.5 seconds for the
   # the objects ItemCount() method to return 10
   # in increments of .5 of a second
   WaitUntil(10.5, .5, self.ItemCount, 10)
except TimeoutError, e:
   print "timed out"

Wait until func(*args) does not raise one of the exceptions in

exceptions

• timeout how long the function will try the function
• retry_interval how long to wait between retries
• func the function that will be executed
• exceptions list of exceptions to test against (default: Exception)
• args optional arguments to be passed to func when called

Returns the return value of the function If the operation times out then the original exception raised is in the 'original_exception' attribute of the raised exception.

e.g.

try:
   # wait a maximum of 10.5 seconds for the
   # window to be found in increments of .5 of a second.
   # P.int a message and re-raise the original exception if never found.
   WaitUntilPasses(10.5, .5, self.Exists, (WindowNotFoundError))
except TimeoutError, e:
   print "timed out"
   raise e.
