How to execute python script(.py) in Robot framework

[Ellendula Sainath]

Hi,

Automated few scripts in python(.py) and i would like to execute the same test case in Robot framework.

for example:

i have .py script:

a,b = 20,20

if (a <> b):

    print "true"

else:

    print "false"

Can anyone please guide me the process to execute the above testcase in Robot framework.

Regards,

Sainath

Ugh

If you are going to only use that script from Robot Framework, then perhaps it would be best to format that script as a library [1]. If you are going to run the script also somewhere else than in the Robot Framework, you could use Process [2] library to run it. It is also combine the two options, by example using the hybrid or dynamic library[1] API.

There is many ways to what you want and which way to go depends on your needs.

Hi,

Thanks for your response!

I have .py script in library file. i.e. C:\Python27\Lib\Hello.py and file consist of print "Hello python!"

The same file we are executing from robot framewok for that created a .txt file as :

*** Settings ***

Library           Process

*** Variables ***

${stdout}

*** Test Cases ***

test2

Run Process python -c E:\Python_practice\Hello.py alias=myproc

${result} = Get Process Result myproc

Should Be Equal ${result.stdout} Hello python!

But test case is failing with 

test2

!= Hello python!

Here test result should match with the output result of E:\Python_practice\Hello.py and given "Should Be Equal ${result.stdout} Hello python!"

Please guide me if i am wrong.

Regards,

Sainath

Ugh

If you write it like this:
| ${result} = | Run Process | python | -c E:\Python_practice\Hello.py |

| Should Be Equal | ${result.stdout} | Hello python! |

does it then work?

Followed as suggested.

Getting error as in log file:

Starting test: Test1 A.Sample test case

20160420 12:48:28.603 :  INFO :

<type 'unicode'>

20160420 12:48:28.962 :  FAIL :  != Hello, world!

Ending test:   test1 A.Sample test case

As per my understanding, here E:\Python_practice\Hello.py is taking as an argument. So it won't execute script from given path and store results in ${result}

Please suggest any other alternative.

You shouldn't be using `-c` option. Another problem is that `\` is an
escape character in Robot Framework test data so you should write the
path like `C:\\Python27\\Lib\\Hello.py`.

Notice also that placing normal Python scripts under the `Lib`
directory is not a good idea. `Lib\site-packages` is the right place
for installed third party modules, but normal scripts generally don't
belong under the Python installation directory.

Hi Peke,

Thank you so much. The suggested method is working fine.

Hi,

I have a python file random.py as below:

 import random

class RandomNum(object):
    def random_number(self):
            num = random.randrange(1, 100000, 1)
            num = str(num)
            print num
            firstname = "Test" + num + ""
            lastname = "Automation" + num + ""
            email = "" + firstname + "." + lastname + "@xyz.com"

I want to use the firstname, lastname and email generated here, in one of my robot test case file. How can I achieve that?

Thanks!

[Hélio Guilherme]

Hi Tamali,

Just to tell you that thread hijacking is not nice. Your question is different from the initial question.

You should ask in a new email, and I would ask you how would you use those firstname, lastname and email from a normal Python program. Then just use those variables from an imported variable file.
