Recently I am attempting doing automation test in python with selenium-robot framework in two different browsers, but I am having an error when i try log the Alias of a Browser. The error says: "Dictionary '@{alias}' has no key '1'".
The code is this on:
*** Settings ***
Library SeleniumLibrary
*** Variables ***
${url} http://google.com
${browser} chrome
*** Test Cases ***
TC to demostrate Browser Operation Keywords in Robot Framework
[Documentation] TC to demostrate Browser Operation Keywords in Robot Framework
Open Browser http://google.com Chrome alias=ChromeRCV
Maximize Browser Window
Open Browser about:blank ff alias=RCVFF
&{alias} Get Browser Aliases
Log @{alias}[1]
@{browser_ID} Get Browser Ids
Log @{browser_ID}[1]
Switch Browser 1
Input Text //*[@id="tsf"]/div[2]/div[1]/div[1]/div/div[2]/input RCVAcademy
Sleep 4s
Switch Browser @{alias}[1]
Go To http://salesforce.com
Close All Browsers
This is due to how Robot interprets the variables. Since you have written @{alias}[1] Robot assumes that the value on index 1 of list alias is also a list. To avoid this issue in future, think first what you want to get out from the variable before assigning the $, @ or &. You can see better explanation in the Robot Framework User Guide.
Consider the below example
&{DICT}= {"key1": "value1", "key2": "value2"}
# Get a list of keys
@{KEYS}= @{DICT.keys}
# ==> @{KEYS}= ["key1", "key2]
# Get a value from dictionary
${VALUE}= ${DICT}[key1]
# ==> ${VALUE}= value1
# Get a value from list
${VALUE}= ${LIST}[0]
# ==> ${VALUE}= key1
As you can see, only when returning a list value, are we using the @ sign. This is because whenever using the @ sign, Robot will interpret the given value as a list of multiple values and attempt to pass each value separately - This is also why normally lists are passed with $ as arguments to make Robot pass them as single variable instead of multiple separate values.
Additionally you are attempting to return a value from a dictionary with a list-like index. This will not work that way - You'll either have to access the value based on the key or then as a list of keys or values.
Since you only need the key to access the browser with the alias, you might as well simply use the following
Log ${aliases.keys()}[1]
# or to log everything in the dictionary
Log ${aliases}
