How to execute Selenium2Library keywords from Python interactive shell?

[Tset Noitamotua]

Hi guys!

Is it possible to execute Selenium2Library (S2L) keywords from Python iteractive shell? I am getting an error when I try:

>>> from robot.libraries.BuiltIn import BuiltIn

>>> s2l = BuiltIn().get_library_instance('Selenium2Library')

Traceback (most recent call last):

  File "<pyshell#19>", line 1, in <module>

    s2l = BuiltIn().get_library_instance('Selenium2Library')

  File "C:\Python27\lib\site-packages\robot\libraries\BuiltIn.py", line 2922, in get_library_instance

    return self._namespace.get_library_instance(name)

  File "C:\Python27\lib\site-packages\robot\libraries\BuiltIn.py", line 70, in _namespace

    return self._context.namespace

  File "C:\Python27\lib\site-packages\robot\libraries\BuiltIn.py", line 65, in _context

    raise RobotNotRunningError('Cannot access execution context')

RobotNotRunningError: Cannot access execution context

Cheers

You can but the method you are using, going straight into Selenium2Library without instantiating robot first, will not work; at least that is my guess from the two lines you've shown and the error message. You can put in pdb set_trace line to jump into the python debugger. Try placing the following line in the code ( somewhere down C:\Python27\lib\site-packages\Selenium2Library or ..\robot) to start the debugger

    import pdb,sys; pdb.Pdb(stdout=sys.__stdout__).set_trace()

(see [1] for a little more information). There should be a set of lines that "start robot" and then allow you to do what you are trying above but can't think of them of the top of my head. Try taking a look at the test runner within the Selenium2Library [2].

@Ed: Thanx for reply!

Could you (or some one else) please provide some more detailed steps. I did not get where to place this peace of code:

 import pdb,sys; pdb.Pdb(stdout=sys.__stdout__).set_trace()

Ugh

The answers depends, to your original question, do you want to run S2L functions, when RF is running or do you want to run S2L functions when RF is not running? Both of them are possible, but requires quite different setup.

I tried to use robotframework-debuglibrary[1] as Robot Framework Shell (rfshell) but I`m getting following error:

> import library  Selenium2Library

< keyword: import library  Selenium2Library

UPDATE: This error happens only with outdated Selenim2Library 1.6.0!

No problem after updating S2L 1.7.4

What I found out so far:

One possibility to execute Selenium2Library from Python Interactive Shell is by using the 'robotframework-debuglibrary' which you can find on Github:

https://github.com/xyb/robotframework-debuglibrary

1. pip install robotframework-debuglibrary

2. pip install pyreadline

3. Open CMD / Shell and call rfshell

4. Now you can use Robot Framework keywords interactively from the shell

5. e.g. Import Library  Selenium2Library (NOTE: put at least to spaces between keywords and arguments)

6. Now you can use all Selenium2Library keywords interactively from the shell

7. e.g. Open Browser   http://www.google.com   Chrome

8. Be happy!

Cheers
