how to pass values from python code to variable of robot framework

问题

I'm beginner in robot framework. I want to pass values from python file to variable of robot framework, but still can't work successfully.

globe.py is my python file and it's very simple.

a = 'this is testing'

below is test case configuration as robot required

*** Setting ***
|Variables|globe.py

*** Variables ***
|${myTest}|${a}

but robot throw error :

"Error in file: Setting variable '${myTest}' failed: Variable '${a}' not found."

could you give some suggestion on that?

here is screen about my execution steps and result

回答1:

It seems to me that your example does work. I use the tab delimited approach, but that shouldn't be the cause.

*** Setting ***
Variables   globe.py

*** Variables ***
${myTest}   ${a}

*** Test Cases ***
A Test Case
     Log To Console    ${myTest}

This resulted into this response from Robot Framework which appears to be what you're looking for.

You can also try to import the variables .py file prior to use..

Import Library   <yourPythonFile.py>
#use variables from python variables file after successful import..

The other workaround is using --variablefile option of robotframework.

Test_varaibles.robot

*** Settings ***
*** Variables ***
*** Test Cases ***
print message to console
  print msg
*** Keywords ***
print msg
  log to console ${msg}

Declare a variable msg in a python file

variable.py

msg='Hello!! This is First msg!'

To pass a variable file, we need to pass –variablefile or -V as a command line argument to pybot

run below command

pybot -V variable.py Test_variables.robot

Result
