Robot framework expected error failed: IndexError: list index out of range

Question

I have a problem with Robot Framework.

Currently I do negative testing. I have a JSON response with length of an array 5 data (counting from 0). I want to check if the 6 th exists or not. If the 6 th data does not exist, the test is passed.

Here's my code:

${msg}    Run Keyword And Expect Error    Resolving variable '${json_response['data'][5]}' failed: IndexError: list index out of range    *    Log To Console    ${json_response['data'][5]}
Should Contain    ${msg}    failed: IndexError: list index out of range

The code gives failing results.

How can I solve this problem?

Answer 1

Better one would be to verify if list length is expecte one:

    ${json_length}    Get Length    ${json_response['data']}
    Should Be Equal As Integers    ${json_length}    6
