What are Variables
Variables are elements used to store values that can be referenced by other elements

RobotFramework has 3 types of variables
SCALAR
LIST
DICTIONARY

we can also use
ENVIRONMENT variables

Step 1 : Open RIDE

Step 2 : Create a Test Case for login

Step 3 : Create a SCALAR variable for url and refer in TestCase
syntax : ${VariableName}

Step 4 : Create a LIST variable for username and password and refer in TestCase
syntax : @{VariableName}

Step 5 : Create a DICTIONARY variable for username and password and refer inTestCase
syntax : &{VariableName}

Environment
%{variable name}

Useful TIPS
=========
1. If a non-existent variable is used in test-data, the keyword using it will fail

2. We can set variables from command line

3. Variables are case-insensitive

4. As best practice use uppercase variable names for global variables
And lowercase variable names for local variables

5. Built in variables - http://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.htm #built-in-variables
