如何使用 python 比较机器人框架的数据输出

Question

here's my robot code

Database-Keywords-Test

connect to database using custom params  cx_Oracle    ${DB_CONNECT_STRING}

${queryResults}=   Query  Select * from QA_USER.SealTest_Security_A order by SECURITY_ID
Log  ${queryResults}

${queryResults1}=   Query  Select * from QA_USER.SealTest_Security_B order by SECURITY_ID
Log  ${queryResults1}

Answer 1

The Robot Framework is written in Python, which makes for a number of good entry points.

You have to make a design decision (or determine the design decision already made by your team) around which to use.

Robot native solution

If the results from the two tables in your system are meant to be identical, you might be able to just use a built-in Robot framework keyword directly and not call out to Python at all.

*** Settings ***
 Documentation    Exercise database keywords (Robot-only).
 Library          Collections
 Library          # <Database library implied above>

*** Test Cases ***
User Settings Test
    [Documentation]    User details db comparison (Database-Keywords-Test)
   ${queryResultsA}=   Query  Select * from QA_USER.SealTest_Security_A order by SECURITY_ID
   ${queryResultsB}=   Query  Select * from QA_USER.SealTest_Security_B order by SECURITY_ID
    Lists Should Be Equal  ${queryResultsA}  ${queryResultsB}

Robot invoking Python solution

If you want Robot to drive Python, ie you invoke robot as the main entry point, you can import Python modules using the Library keyword.

Robot test case:

*** Settings ***
 Documentation    Exercise database keywords (call out to Python).
 Library          userManagement
 Library          # <Database library implied above>

*** Test Cases ***
User Settings Test
    [Documentation]    User details db comparison (Database-Keywords-Test)
   ${queryResultsA}=   Query  Select * from QA_USER.SealTest_Security_A order by SECURITY_ID
   ${queryResultsB}=   Query  Select * from QA_USER.SealTest_Security_B order by SECURITY_ID
    ${diff} = Compare Users  ${userResultsA}  ${userResultsB}
    Should Be Empty  ${diff}

Python library userManagement.py:

class UserManagement:

    ROBOT_LIBRARY_SCOPE = 'TEST SUITE'

    def compareUsers(self,userResultsA,userResultsB):
        # diff implementation depends on the structure of user results
        # which are not shared in the question, but will be related to the 
        # database library you are using, perhaps a list of 
        # rows or dictionaries
        ...
        return diff

Python invoking Robot solution

If you want python to drive Robot, you can access the API from Python https://robot-framework.readthedocs.io/en/latest/

The above are some directly related stubs that hopefully let you see the mapping and get off the ground. Using that starting point, I suggest working through the documentation links carefully for next steps.
