Robot Framework in Python

Here’s a complete, detailed guide to Robot Framework — now including installation, environment setup, and test execution commands.

---

🤖 Robot Framework — Complete Overview

---

🧩 1️⃣ What is Robot Framework

Robot Framework (RF) is an open-source, keyword-driven test automation and RPA framework that enables both technical and non-technical testers to:

• Write human-readable test cases
• Automate Web, API, Database, Mobile, and Desktop testing
• Run in CI/CD pipelines (Jenkins, Azure DevOps, etc.)

It is language-agnostic but most commonly extended in Python.

⚙️ 2️⃣ Installation Steps

Robot Framework runs on Python, so let’s start there.

🔸 Step 1: Install Python

Download from https://www.python.org/downloads Make sure to check “Add Python to PATH” during installation.

Verify installation:

python --version
pip --version

---

🔸 Step 2: Install Robot Framework Core

pip install robotframework

Verify installation:

robot --version

You should see something like:

Robot Framework 7.0 (Python 3.12)

---

🔸 Step 3: (Optional) Install Additional Libraries

Purpose	Library	Installation
Web Automation	SeleniumLibrary	pip install robotframework-seleniumlibrary
API Testing	RequestsLibrary	pip install robotframework-requests
Database	DatabaseLibrary	pip install robotframework-databaselibrary
Mobile	AppiumLibrary	pip install robotframework-appiumlibrary
RPA / Desktop	rpaframework	pip install rpaframework
Playwright	robotframework-browser	robotframework-browser

---

🔸 Step 4: (Optional) Install Browser Drivers

For web testing, you’ll need a browser driver (like Selenium):

• Chrome → Install ChromeDriver
• Edge/Firefox/Safari → Install corresponding driver

Make sure it’s added to your system PATH.

🧱 3️⃣ Folder Structure

A clean project setup looks like this:

robot-tests/
│
├── tests/
│   ├── login_tests.robot
│   ├── api_tests.robot
│
├── resources/
│   ├── keywords.robot
│   ├── variables.robot
│
├── libraries/
│   └── custom_keywords.py
│
├── results/
│   ├── log.html
│   ├── report.html
│
└── requirements.txt

🧠 4️⃣ Core Concepts Recap

Concept	Description
Test Suite	Collection of test cases in .robot files
Test Case	Individual test scenario
Keyword	A reusable action or command
Variable	A placeholder for values
Library	External module that adds functionality
Resource File	Contains shared keywords or variables

---

🧪 5️⃣ Example Test Case — Selenium

tests/example_web_test.robot

*** Settings ***
Library    SeleniumLibrary

*** Variables ***
${URL}    https://example.com
${BROWSER}    Chrome

*** Test Cases ***
Verify Example Domain Title
    Open Browser    ${URL}    ${BROWSER}
    Title Should Be    Example Domain
    [Teardown]    Close Browser

---

🧪 6️⃣ Example Test Case — API

tests/api_test.robot

*** Settings ***
Library    RequestsLibrary

*** Variables ***
${BASE_URL}    https://jsonplaceholder.typicode.com

*** Test Cases ***
Verify Get User Details
    Create Session    jsonAPI    ${BASE_URL}
    ${response}=    Get Request    jsonAPI    /users/1
    Should Be Equal As Integers    ${response.status_code}    200
    Log To Console    ${response.json()}

---

🚀 7️⃣ Running Tests

Run All Tests

robot tests/

Run Specific File

robot tests/example_web_test.robot

Run Tests by Tag

robot -i smoke tests/

Specify Output Directory

robot --outputdir results tests/

---

📊 8️⃣ Test Reports

After running, Robot Framework automatically creates:

File	Purpose
log.html	Detailed execution log
report.html	Summary report
output.xml	Machine-readable report (for CI/CD)

Open them in a browser — they include test results, screenshots (if configured), and timing info.

---

🧩 9️⃣ Extending Robot Framework

You can define your own custom keywords using Python or Java.

Example: Python Custom Library

libraries/custom_keywords.py

from robot.api.deco import keyword

@keyword("Add Two Numbers")
def add_two_numbers(a, b):
    return int(a) + int(b)

Then use it in Robot:

*** Settings ***
Library    ../libraries/custom_keywords.py

*** Test Cases ***
Add Numbers
    ${result}=    Add Two Numbers    3    7
    Should Be Equal As Integers    ${result}    10

---

🔁 🔟 CI/CD Integration

Robot Framework easily integrates with:

• Jenkins (via Robot Plugin)
• Azure DevOps Pipelines
• GitHub Actions
• GitLab CI
• Docker (containerized test runs)

Example Jenkins command:

robot --outputdir reports tests/

---

🧮 11️⃣ Advantages

✅ Simple, readable syntax ✅ Modular — reusable keywords ✅ Supports Web, API, DB, and Mobile testing ✅ Easy CI/CD integration ✅ Great reports out of the box ✅ Can use Python or Java libraries ✅ Active community & rich plugin ecosystem

---

⚠️ 12️⃣ Limitations

❌ Not suited for low-level or very complex logic ❌ Can be verbose for conditions/loops ❌ Debugging requires looking into reports ❌ Slower than raw code frameworks
