4. Sections in Robot Framework

A Robot Framework file is divided into different sections. Each section has its own purpose.

Main Sections in Robot Framework

Section	Purpose
* Settings *	Used for library imports and resource files
* Variables *	Used to store variables
* Test Cases *	Contains all test cases
* Keywords *	Contains reusable user-defined keywords

Example of All Sections

*** Settings ***
Library    SeleniumLibrary

*** Variables ***
${URL}    https://google.com

*** Test Cases ***
Open Google
    Open Browser    ${URL}    chrome
    Close Browser

*** Keywords ***
Launch Application
    Open Browser    ${URL}    chrome

Why Sections are Important?

Improve code readability
Easy framework maintenance
Better test organization
Reusable automation code

5. Variables in Robot Framework

Variables are used to store data in Robot Framework. Using variables makes automation scripts reusable and easy to maintain.

Types of Variables

Variable Type	Syntax
Scalar Variable	${variable}
List Variable	@{list}
Dictionary Variable	&{dictionary}

Scalar Variable Example

*** Variables ***
${NAME}    Chandan

*** Test Cases ***
Print Name
    Log    ${NAME}

List Variable Example

*** Variables ***
@{COLORS}    Red    Green    Blue

*** Test Cases ***
Print Colors
    Log    ${COLORS}[0]
    Log    ${COLORS}[1]

Dictionary Variable Example

*** Variables ***
&{USER}    username=admin    password=admin123

*** Test Cases ***
Login Data
    Log    ${USER}[username]
    Log    ${USER}[password]

Advantages of Variables

Avoid hardcoded values
Easy maintenance
Reusable scripts
Supports dynamic execution

6. Keywords in Robot Framework

Keywords are the most important concept in Robot Framework. Everything in Robot Framework works using keywords.

Types of Keywords

Keyword Type	Description
Built-in Keywords	Provided by Robot Framework
Library Keywords	Provided by libraries like SeleniumLibrary
User-defined Keywords	Created by users

Built-in Keyword Example

*** Test Cases ***
Example Test
    Log    Welcome to Way2Testing

User-defined Keyword Example

*** Test Cases ***
Login Test
    Launch Browser

*** Keywords ***
Launch Browser
    Open Browser    https://google.com    chrome

Advantages of Keywords

Code reusability
Easy maintenance
Readable test cases
Reduced duplicate code

7. Control Statements in Robot Framework

Control statements are used to execute automation flow based on conditions and loops.

IF ELSE Condition Example

*** Variables ***
${AGE}    20

*** Test Cases ***
Age Validation
    IF    ${AGE} > 18
        Log    Adult User
    ELSE
        Log    Minor User
    END

FOR Loop Example

*** Variables ***
@{FRUITS}    Apple    Mango    Banana

*** Test Cases ***
Print Fruits
    FOR    ${fruit}    IN    @{FRUITS}
        Log    ${fruit}
    END

WHILE Loop Example

*** Test Cases ***
Counter Example
    ${count}=    Set Variable    1

    WHILE    ${count} < 5
        Log    ${count}
        ${count}=    Evaluate    ${count}+1
    END

Why Control Statements are Important?

Dynamic execution
Data-driven testing
Decision making
Loop execution

8. Tags in Robot Framework

Tags are used to categorize test cases. They help in executing selected test cases.

Tag Example

*** Test Cases ***
Login Test
    [Tags]    smoke    regression
    Log    Login Successful

Run Test Using Tag

robot -i smoke test.robot

Exclude Tag Example

robot -e regression test.robot

Commonly Used Tags

Tag	Purpose
smoke	Basic validation tests
regression	Complete feature testing
sanity	Quick validation after fixes

9. Setup & Teardown in Robot Framework

Setup and Teardown are used to execute pre-condition and post-condition steps.

What is Setup?

Setup runs before test execution.

What is Teardown?

Teardown runs after test execution.

Test Setup & Teardown Example

*** Settings ***
Test Setup       Open Browser    https://google.com    chrome
Test Teardown    Close Browser

*** Test Cases ***
Search Test
    Input Text    name=q    Robot Framework

Suite Setup & Suite Teardown

Suite Setup runs once before all test cases. Suite Teardown runs once after all test cases.

Example

*** Settings ***
Suite Setup       Log    Starting Test Suite
Suite Teardown    Log    Closing Test Suite

Advantages of Setup & Teardown

Avoid duplicate code
Centralized execution flow
Easy maintenance
Better framework structure

Best Practices for Beginners

Use reusable keywords
Avoid hardcoded values
Use proper tags
Create modular test cases
Use setup and teardown properly
