Using Selenium with Python for Automated Testing
Every tester aims to ensure that all software components are functional and user-friendly. This is why many teams turn to Selenium to conduct effective test automation. However, the true potential of pairing it with Python often remains untapped.
The Significance of Automation in Testing
As software applications grow more complex, manual testing becomes increasingly tedious. Validating all aspects to ensure the application is functional across various platforms and services requires teams to embrace automation.
Automation testing significantly reduces the risk of human error while minimizing the time and cost of testing. By streamlining tiresome manual tasks with the help of automation frameworks, teams can detect the smallest of defects. They can also accelerate testing across various parameters, browsers, and platforms. Such seamless cross-browser testing ensures the application works as it should.
Automation testing helps detect errors and changes with great precision. By introducing automation in the CI/CD pipeline, teams can accurately detect functional problems or visual regressions in the UI. In addition, they can minimize runtime and improve the overall efficiency of running test cases across any number of device/OS combinations.
- Human errors or bugs
- Slow loading or performance issues
- Incorrect implementation of product features
- Security-related flaws
- Non (or partial) implementation of customer requirements
Traditionally, software testing was executed later in the software development lifecycle (SDLC). This was inefficient, as software testers had a limited timeframe to detect flaws before the final product release. This is no longer the case in the age of DevOps and Agile management.
Also referred to as software testing lifecycle (or STLC), software testing in an Agile testing environment is a continuous testing process designed for modern product requirements.
What are the different types of software testing? Let's discuss that next.
Why Choose Selenium?
Selenium is popularly used as a framework for automated UI testing. Being an open-source framework, it allows testing teams to test applications across multiple browsers, operating systems, and devices. Many teams are now using Selenium with Python to enable end-to-end test automation.
So, what sets Selenium apart as a preferred tool? There are five primary reasons why teams prefer Selenium:
Flexibility
The Selenium framework offers high levels of flexibility to test applications across multiple browsers and operating systems. When integrated with third-party frameworks and add-ons, it broadens the scope of testing. Teams can also regroup and retract test cases and make quick changes to the underlying code. This helps reduce duplication, minimize complications, and enhance maintainability.
Compatibility
Selenium supports all major programming languages, including Java, Python, JavaScript, C#, Ruby, and Perl. Teams can write scripts in the language of their choice and have it converted into a Selenium-compatible language. This compatibility ensures comprehensive and end-to-end testing across the tech stack.
Ease of Use
As an open-source automation framework, Selenium offers a user-friendly interface. With the community continuously growing, testers can leverage a host of new features to customize test scripts, create automated tests, and enhance the functionality of predefined functions and classes.
Parallel Testing
Selenium delivers on the promise of saving time and effort in automated testing. With built-in support for five languages, it allows for parallel testing of applications. For example, using the Selenium grid, testers can test across hundreds of browsers simultaneously and accelerate software delivery and deployment.
Speed
The ability to run automated tests on multiple machines helps speed up test execution. This is another major factor driving the continued adoption of Selenium for automated testing.
Prerequisites
If you want to use Selenium with Python for test automation, there are some prerequisites that you need to meet. These include:
- The latest versions of Selenium and Python
- The Selenium API
- Any suitable IDE to write and run test scripts
- A modern browser to automate the Python testing process for different devices
Getting Started
To get started, here's what you need to do:
- Run the “Install Selenium” command and create a new Python script.
- Open a test editor and import the Selenium library.
- Create a new instance of the web driver class that represents the web browser you will be using to run the tests.
- Start the Python testing process by writing a script of your choice.
Selenium Comes with Some Limitations
As seen above, Selenium is a popular framework that helps in automating the testing of web applications. But despite the many benefits, Selenium also has some drawbacks. For instance, the framework offers:
Restricted Test Management
Selenium is primarily designed for web applications and doesn't cater to mobile or desktop applications. It can also only access web elements inside the web applications and none outside of it. This necessitates the use of additional tools or frameworks to enable end-to-end testing.
Limited Automation Capabilities
While Selenium facilitates testing across various browsers, its automation speed can sometimes be slow. This this open source test automation framework takes a substantial amount of time to load pages, interact with elements, and wait for elements to appear. Limimted support for testing desktop applications and lack of built-in reporting makes it difficult to reduce costs, save time and resources, and mitigate emerging business risks.
Poor Reporting
Selenium is also known for its poor reporting capabilities. To enable comprehensive reporting, teams must integrate it with other tools or frameworks. In addition, it does not offer any guaranteed user support. In fact, teams often depend on the community to find answers to new problems.
Why ACCELQ is Preferred For Test Automation Over Selenium
Given the drawbacks of Selenium, many teams are seeking a new and intelligent tool for test automation. ACCELQ is a widely sought-after tool that empowers teams to automate web interactions and perform robust testing of web applications.
