python - 如何使用 python 比较机器人框架的数据输出

Question

这是我的机器人代码

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

机器人框架是用 Python 编写的，这提供了许多很好的入口点。

您必须做出要使用的设计决策(或确定您的团队已经做出的设计决策)。

机器人原生解决方案

如果系统中两个表的结果是相同的，您也许可以直接使用内置的 Robot 框架关键字，而根本不调用 Python。

*** 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}

机器人调用Python解决方案

如果您希望Robot驱动Python，即调用robot作为主要入口点，您可以使用Library关键字导入Python模块。

机器人测试用例:

*** 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 库 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调用Robot解决方案

如果你想让Python驱动Robot，你可以从Python访问API https://robot-framework.readthedocs.io/en/latest/
