Understanding the Benefits of Using Page Objects in Selenium

3 July 2024 Stephan Petzl Leave a comment QA

As you delve deeper into Selenium for automated testing, you may come across the concept of Page Objects. This article aims to explain the advantages and disadvantages of using Page Objects compared to a mere collection of functions. By the end, you’ll have a clearer understanding of when and why to use Page Objects in your test automation strategy.

Advantages of Using Page Objects

Page Objects offer several key benefits that can significantly enhance the maintainability and readability of your test scripts:

  • Separation of Concerns: Page Objects help in separating the test code from the navigation code. This separation makes the test code easier to comprehend and maintain.
  • Ease of Maintenance: When there are changes in the UI, you only need to update the navigation code within the Page Object. The test logic remains unchanged, provided the application logic is still the same.
  • Contextual Clarity: Using methods like LoginPage.clickNext() or ItemDetails.clickNext() provides immediate context about the page you are interacting with, making the test more readable.
  • Code Reusability: Page Objects allow you to define UI elements and actions once and reuse them across multiple tests, adhering to the DRY (Don’t Repeat Yourself) principle.
  • Self-Documenting Tests: Methods within Page Objects can be named meaningfully, making the tests self-explanatory and easier to understand for anyone reviewing the code.

Disadvantages of Using Page Objects

Despite the numerous advantages, there are a few drawbacks to consider:

  • Initial Setup Time: Designing and implementing Page Objects can be time-consuming initially. However, this upfront investment pays off in the long run.
  • Programming Skills Required: Implementing Page Objects requires a good understanding of programming concepts and design patterns, which might be a challenge for teams with limited coding experience.

Practical Example

Consider the following example to illustrate the difference between using Page Objects and a collection of functions:

Without Page Objects


selenium.type(username);
selenium.type(password);
selenium.click(submit);
selenium.waitForPageToLoad(waitPeriod);
  

With Page Objects


LoginPage.login(username, password);
  

The latter is more succinct and easier to read, demonstrating the clarity and maintainability that Page Objects bring to your test automation code.

Conclusion

Incorporating Page Objects in your Selenium test automation framework can lead to more maintainable, readable, and reusable code. While the initial setup might require some effort, the long-term benefits of improved code organization and reduced maintenance make it a worthwhile investment.

If you’re looking for a solution that simplifies test automation even further, consider using tools like Repeato. Repeato is a No-code test automation tool for iOS and Android that leverages computer vision and AI to create, run, and maintain automated tests. It’s particularly fast to edit and run tests, making it an excellent choice for quality assurance teams looking to streamline their testing processes without diving deep into code.
