By the end of this article, you'll have a deep understanding of how to leverage Robot Tester to ensure your applications are robust, reliable, and user-friendly.
What is Robot Tester?
Robot Tester refa ers to the usage of Robot Framework for automated testing. Robot Framework is an open-source test automation framework that is keyword-driven, meaning it uses keywords to specify test cases, making it easy to read and write tests. This framework is highly flexible and can be used for testing various applications, including web apps, APIs, and desktop applications.
Key Features of Robot Tester
Keyword-Driven Testing: This feature allows users to create test cases in a readable and understandable format, making it accessible even for non-programmers.
Extensibility: Robot Framework supports external libraries, which can be integrated to extend its functionality, including SeleniumLibrary for web testing.
Platform Independence: Robot Framework is platform-independent and can run on Windows, macOS, and Linux, ensuring broad usability.
Detailed Reporting: It generates detailed test reports and logs, making it easier to analyze test results and diagnose issues.
Integration with Tools: Robot Framework integrates seamlessly with various tools and platforms, including Jenkins, Selenium, and Applitools, to enhance its testing capabilities.
Why Use Robot Tester?
Simplified Test Case Creation
One of the main advantages of using Robot Tester is the simplicity of test case creation. The keyword-driven approach allows even those with minimal programming experience to write effective test cases. This accessibility can significantly reduce the learning curve for teams new to test automation.
Reusability and Maintainability
Robot Framework encourages the use of reusable keywords, which can be defined once and used across multiple test cases. This not only reduces redundancy but also makes maintaining tests easier as changes can be made in one place and applied universally.
Scalability for Large Projects
Robot Tester is highly scalable, making it suitable for both small and large projects. Its modular approach allows you to organize test cases into suites, making it easier to manage and scale your testing efforts as the project grows.
Integration with CI/CD Pipelines
In today’s DevOps-driven environments, continuous integration and continuous deployment (CI/CD) are critical. Robot Tester integrates well with CI/CD tools like Jenkins, allowing automated tests to be executed as part of the build process, ensuring that issues are detected early in the development cycle.
Getting Started with Robot Tester
Step 1: Setting Up the Environment
To start using Robot Tester, you need to prepare your environment with a few essential tools:
Python: Robot Framework requires Python, so ensure you have Python 3.6 or higher installed on your system.
Robot Framework: Install Robot Framework using pip, Python’s package manager, with the command:
bash
pip install robot frameworkSeleniumLibrary: For web application testing, you’ll need to install SeleniumLibrary:
bash
pip install robot framework-selenium libraryWebDriver: Depending on the browser you intend to test, install the appropriate WebDriver (e.g., ChromeDriver for Chrome).
Editor: A good editor with Robot Framework support, like Visual Studio Code, will enhance your productivity by providing syntax highlighting and other useful features.
Step 2: Creating a Test Case
Once your environment is set up, you can create your first test case. A typical test case in Robot Tester looks something like this:
robot
*** Settings ***
Library SeleniumLibrary
*** Variables ***
${URL} https://example.com
${BROWSER} Chrome
*** Test Cases ***
Open Browser and Verify Title
Open Browser ${URL} ${BROWSER}
Title Should Be Example Domain
[Teardown] Close BrowserIn this simple test case, the browser is opened, the title of the page is verified, and then the browser is closed.
Step 3: Running the Test
To run your test, navigate to the directory where your test case is saved and execute the following command:
bash
robot <test-case-file-name>.robotRobot Framework will execute the test and generate a detailed report and log in the same directory. These fileto s can be opened in a browser to view the test results.
Step 4: Adding Visual Testing with Applitools
Visual testing can help you catch issues that traditional text-based assertions might miss, such as layout shifts or visual bugs. To integrate visual testing with Robot Tester, you can use Applitools Eyes.
First, install the Applitools Eyes SDK for Robot Framework:
bash
pip install eyes-robotframeworkNext, configure the Applitools settings in your test case:
robot
*** Settings ***
Library SeleniumLibrary
Library EyesLibrary runner=web_ufg config=applitools.yaml
*** Test Cases ***
Visual Test Example
Open Browser https://example.com headlesschrome
Eyes Open
Eyes Check Window Example Page Fully
Eyes Close Async
Close BrowserThis test will capture a visual snapshot of the web page and compare it with the baseline in Applitools Test Manager, allowing you to detect any visual differences.
Advanced Features of Robot Tester
Data-Driven Testing
Robot Tester supports data-driven testing, allowing you to run the same test with different inputs. This is particularly useful for testing scenarios with multiple input variations. You can use the FOR loop syntax in Robot Framework to iterate through different data sets.

Data-Driven Test
[Template] Test With Multiple Inputs

For large test suites, running tests in parallel can significantly reduce execution time. Pabot is a tool that allows Robot Framework tests to be run in parallel.
To use Pabot, install it via pip:
bash
pip install robotframework-pabotRun your tests in parallel with the following command:
bash
pabot --processes 4 <test-suite-directory>Pabot will distribute your test cases across the specified number of processes, speeding up the overall test execution.
Continuous Integration with Jenkins
Integrating Robot Tester with Jenkins is straightforward and allows you to include automated tests in your CI/CD pipeline. You can configure a Jenkins job to run your Robot Framework tests after each build. The test results can be published using the Robot Plugin for Jenkins, which displays test results in a user-friendly format.
To set up Jenkins with Robot Framework:
Install the Robot Plugin: Go to Manage Jenkins > Manage Plugins and install the Robot Framework plugin.
Configure the Job: In your Jenkins job configuration, add a build step to execute your Robot Framework tests.
Publish Results: Use the post-build action "Publish Robot Framework test results" to generate reports in Jenkins.
Debugging and Troubleshooting
Debugging Robot Framework tests can be done using built-in logs and reports. The generated logs provide detailed information about each test step, including screenshots for failed steps if you’re using SeleniumLibrary. These logs are essential for identifying the root cause of failures.
For more complex issues, you can use breakpoints and step-through debugging using a tool like RIDE or Pycharm with Robot Framework support.
Best Practices for Using Robot Tester
Modular Test Design
Break down your test cases into smaller, reusable keywords. This modular approach makes your tests easier to maintain and reduces redundancy.
Consistent Naming Conventions
Use consistent naming conventions for your test cases, keywords, and variables. This improves readability and makes it easier to understand the purpose of each test.
Regular Maintenance
As your application evolves, your test cases need to be updated to reflect changes in the UI or functionality. Regularly review and update your tests to ensure they remain effective.
Comprehensive Test Coverage
Aim to cover as many scenarios as possible in your tests. This includes positive, negative, and edge cases to ensure your application behaves as expected in all situations.
