How to define a variable being a dictionary with list values in Robot Framework

问题

In one of my testcases I need to define a dictionary, where the keys are string and the values are arrays of strings. How can I do so in Robot Framework?

My first try using a construct as shown below, will not work.

*** Variables ***
&{Dictionary}     A=StringA1  StringA2   
...               B=StringB1   StringB2

Another idea might be to use Evaluate and pass the python expression for a dictionary, but is this the only way how it can done?

*** Variables ***
&{Dictionary}     Evaluate  { "A" : ["StringA1",  "StringA2"], "B": ["StringB1","StringB2"]}

回答1:

You have a couple more options beside using the Evaluate keyword.

1. You could use a Python variable file:

   DICTIONARY = { "A" : ["StringA1",  "StringA2"], "B": ["StringB1","StringB2"]}
   

   Suite:

   *** Settings ***
   Variables    VariableFile.py
   
   *** Test Cases ***
   Test
       Log    ${DICTIONARY}
   

2. You can define your lists separately, and then pass them as scalar variables when defining the dictionary.

   *** Variables ***
   @{list1}    StringA1    StringA2
   @{list2}    StringB1    StringB1
   &{Dictionary}    A=${list1}    B=${list2}
   
   *** Test Cases ***
   Test
       Log    ${Dictionary}
   

3. You can create a user keyword using the Create List and Create Dictionary keywords. You can achieve the same in Python by writing a small library.

   *** Test Cases ***
   Test
       ${Dictionary}=    Create Dict With List Elements
       Log    ${Dictionary}
   
   
   *** Keyword ***
   Create Dict With List Elements
       ${list1}=    Create List    StringA1    StringA2
       ${list2}=    Create List    StringB1    StringB1
       ${Dictionary}=    Create Dictionary    A=${list1}    B=${list2}
       [return]    ${Dictionary}
