wait until keyword succeeds with users own library keyword

[Petri]

Hi,

can this BuiltIn keyword be used in a python library? I have a Python lib function and try like this:

  BuiltIn().wait_until_keyword_succeeds("1 min", "3 sec",  self.is_configuration_state_ready())

Here is my function:

  def is_configuration_state_ready(self):
      return self.ConfigurationDialog.Ready == True

Error:

File "C:\Programdata\Anaconda2\Lib\site-packages\robot\libraries\BuiltIn.py", line 2008, in wait_until_keyword_succeeds
  File "C:\Programdata\Anaconda2\Lib\site-packages\robot\libraries\BuiltIn.py", line 1596, in run_keyword
RuntimeError: Keyword name must be a string.

Is there some workaround, like Python function that could be used instead?

Thanks for your help!

Hi,

You can use WUKS with your own keywords, but you need to pass the
keyword to execute as a name only like
`BuiltIn().wait_until_keyword_succeeds("1 min", "3 sec", "Is
Configuration State Ready")`. I guess we could enhance WUKS to work
also with any callable, but at least in this case using WUKS is not a
good idea in general for various reasons:

1. WUKS creates lot of keywords internally which can increase
output.xml and log.html size considerably.
2. Your keyword "Is Configuration State Ready" can never fail. It
returns either True or False, but Robot uses exceptions to report
failures.
3. You can easily implement the same logic as WUKS does in Python
using a while loop and handling possible exceptions.
