Variable from one Test cant be used in other(Variable 'token' is used, but not defined)-CodePudding

I have the following two tests,

*** Settings ***

Library CustomizeLibrary

*** Variables ***

${username} anti

${password} anti

${headers} {"Content-Type": "application/json"}

*** Test Cases ***

GET Users'

${token}    Customize Get Token    http://127.0.0.1:5000/api/auth/token    ${token}  (Gives error: Variable 'token' is used, but not defined)

GET token based on existing user

${token}=    Customize Get Token    http://127.0.0.1:5000/api/auth/token    ${username}    ${password}    ${headers}
Set suite variable    ${token}

${token} is defined and set as suite variable in previous test not yet able to use it, Any sugession ?

CodePudding user response：

It is called a "static variable", a variable that is not restricted to a single test/method/class instance (Google for more info). This variable exists outside all your tests.

How to implement: Static Variables in Robot Framework

*** Settings *** 
... 
*** Variables *** 
.... other variables ....
${token}= Customize Get Token http://127.0.0.1:5000/api/auth/token ${username} ${password} ${headers}

Remark: your tests should be independent. You do NOT want 1 test to run first, otherwise the next one fails. Trust me, it is a anti Pattern and causes a world of hurt. Place the GetToken in an initializer/constructor to prevent issues.

CodePudding user response：

I would suggest looking at setting the suite variable during Suite Setup by calling a keyword to initialize the variable. It will run before tests and eliminates dependency between tests.

Here is a dummy example:

*** Settings ***
Suite Setup  Init Suite Variable

*** Test Cases ***
Scenario: Test 1 - Suite Variable
    Log To Console  ${suite_variable}

Scenario: Test 2 - Test Variable 
    Init Test Variable
    Log To Console  ${test_variable}

*** Keywords ***
Init Suite Variable 
    Set Suite Variable  ${suite_variable}  I'm at suite level

Init Test Variable 
    Set Test Variable   ${test_variable}  I'm at test level
