What is Robot Framework Python?
Robot Framework Python, often referred to simply as Robot Framework, is an open-source test automation framework that utilizes a keyword-driven approach. It provides an easy-to-use syntax that allows users to write test cases in a natural language format. The framework is implemented in Python, making it highly flexible and extensible.
How does Robot Framework Python work?
At its core, Robot Framework Python operates based on a simple and intuitive principle. Test cases are written using keywords that represent actions or operations to be performed. These keywords are organized into test suites, which can be executed individually or as a whole. The framework also offers a wide range of built-in libraries and supports external libraries, allowing for seamless integration with other tools and technologies.

The Architecture of the Robot Framework
The robot framework is designed to provide a flexible and extensible platform for developing and executing robot programs. At its core, the framework consists of several key components that work together seamlessly to enable efficient robot operations. Let’s take a closer look at each of these components.
Component 1: Test Data
In the robot framework, test data is organized in a tabular format known as test cases. Each test case consists of a series of steps, along with associated keywords and arguments. Test data can be written in plain text or using a markup language like HTML or XML. This flexibility allows developers to create test cases that are easy to read and maintain.
Component 2: Test Library
The test library is a collection of reusable code that provides keywords for executing various actions within test cases. It acts as a bridge between the test data and the system under test, enabling the robot framework to interact with external resources such as databases, APIs, or user interfaces. Test libraries can be implemented in a variety of programming languages, including Python, Java, or C#. This versatility allows developers to leverage their existing skills and libraries while building robot programs.
Component 3: Test Runner
The test runner is responsible for executing test cases and reporting the results. It reads the test data, invokes the appropriate keywords from the test library, and captures the outcome of each step. The test runner also handles exception handling, logging, and generating detailed reports. With its powerful reporting capabilities, the test runner provides valuable insights into the test execution process, making it easier to identify and debug issues.
Component 4: Resource Files
Resource files contain reusable keywords, variables, and settings that can be shared across multiple test cases. They provide a centralized location for storing common functionality, making it easier to maintain and update robot programs. By separating test data from resource files, the robot framework promotes modularity and reusability, allowing developers to create scalable and maintainable test suites.
Component 5: Variables and Arguments
Variables and arguments play a crucial role in the robot framework, enabling dynamic and data-driven test cases. Variables allow developers to store and manipulate data, while arguments provide a way to pass values to keywords. This flexibility allows for the creation of reusable test cases that can be easily adapted to different scenarios. Variables and arguments can be defined at various levels, from test case level to suite level, providing granular control over data management.
Component 6: Built-in Libraries
The robot framework comes bundled with a set of built-in libraries that provide common functionality out of the box. These libraries cover a wide range of areas, including file operations, string manipulation, network communication, and more. By leveraging the built-in libraries, developers can accelerate the development process and focus on implementing domain-specific functionality.
Leveraging Built-in Libraries for Enhanced Functionality
One of the strengths of Robot Framework Python lies in its extensive set of built-in libraries. These libraries provide ready-to-use keywords for performing common tasks, saving you time and effort. Let’s explore some of the built-in libraries and their applications:

\ ${page} Evaluate ${page} + 1
\ Wait Until Page Contains Showing ${page}-
Log Many ${products}
Close Browser
In this script, we first import the SeleniumLibrary to leverage Selenium functionality within Robot Framework. We then define some variables such as ${BROWSER} (set to Chrome), ${URL} (set to the Amazon website), ${SEARCH_TERM} (set to the term you want to search on Amazon), and ${MAX_PAGES} (set to the maximum number of pages you want to scrape).
The test case named “Scrape Amazon Products” demonstrates how to perform scraping. It opens the browser with the specified URL, enters the search term in the search box using the Input Text keyword, and clicks the search button using the Click Button keyword. It then waits until the page contains the text “Showing 1-” to ensure that the search results have loaded.
The script uses a loop to iterate through each page of search results, defined by the ${MAX_PAGES} variable. Within the loop, it uses the Get WebElements keyword to locate all the product elements on the page. It then iterates through each product element and extracts the product name using the Get Text keyword. The product names are appended to the ${products} list variable.
After scraping all the pages, the script logs the contents of the ${products} list using the Log Many keyword. You can customize the script to extract additional data or perform specific actions on the scraped data.
Remember to install the required libraries (such as Robot Framework and SeleniumLibrary) and have the appropriate web drivers (like ChromeDriver) configured before running the script.
Note: Web scraping may be subject to legal and ethical considerations. Ensure that you comply with the terms of service of the websites you are scraping and respect the website’s policies regarding automated access and data extraction.
