With the expanding array of devices and web browsers used by internet users, it’s become crucial for developers to prioritize creating content that displays properly across these various platforms. While manually testing content on individual browsers is an option, a more agile approach encourages automating this repetitive cross-browser testing task. Selenium has emerged as the preferred choice for developers to automate this process.

Selenium, a widely used open-source tool, empowers developers to define and automate tests for web applications. This versatile framework supports multiple programming languages such as Java, Python, JavaScript, and C#, making web testing more accessible. While Selenium has significantly streamlined web testing for organizations worldwide, its open-source nature poses certain challenges. Fortunately, most issues testers encounter have direct solutions, which is why we’ve detailed the most common Selenium challenges in this blog.

Top Challenges in Selenium Automation Testing

1. Dynamic Content

Websites employing advanced technologies may feature dynamic content that evolves over time. Even globally accessible sites might display content specific to different geographical locations.

For example, Amazon’s e-commerce platform constantly updates its catalog and behaves differently across regions. Automating these sites using Selenium can be tricky due to potential locator failures with web elements and test script vulnerabilities caused by AJAX-based content delays. Selenium’s Implicit and Explicit waits, alongside customized XPath expressions, offer solutions to manage dynamic web content.

2. Mobile Testing

Testing responsive design in Selenium encounters a new hurdle when it comes to mobile operating systems due to its inability to run on native platforms such as iOS and Android. However, within the Selenium family, there’s a specialized testing framework called Appium that helps in testing content on iOS and Android native mobile operating systems. Appium operates through the WebDriver protocol, enabling automated testing of mobile apps. With the surge in user migration to mobile devices, it’s natural that developers and testers are capitalizing on the capabilities of Appium for this very purpose.

3. Cross Browser Testing

At times, our web application might behave differently across various browsers, leading to potential disparities between Chrome and Firefox. Given the multitude of browsers available today, it’s impractical to automate tests for every single one. Nevertheless, it is still important to ensure the application is fully compatible with major browsers like Chrome, Firefox, Safari, Edge, and IE.

Confining tests to only these commonly used browsers won’t suffice. It’s essential to broaden the scope of testing by including popular versions of these browsers, various operating systems, and diverse screen resolutions. It’s essential to broaden the scope of testing by encompassing prevalent versions of these browsers, different operating systems, and a range of screen resolutions. This approach, referred to as cross-browser testing, poses a substantial challenge for testers involved in automated testing.

4. Handling Pop-Ups

While simpler alternatives are generally preferred over using pop-ups, individuals continuing to utilize them may encounter challenges when attempting to automate tests using Selenium, particularly in handling pop-ups. Although WebDriver can manage browser-based pop-ups, Selenium testing is limited in addressing OS-based pop-ups, representing one of its notable constraints. An example of a non-browser-based pop-up is the prompt to retain a downloaded executable file.

Selenium lacks inherent support for OS-based dialog windows. However, there are extensions available to mitigate this limitation. One approach involves integrating Selenium with AutoIt, a tool capable of automating Windows-based user interfaces. Depending on the scripting language employed, a bridge like the Jacob COM bridge in Java might be necessary to connect Selenium with AutoIt.

5. Scalability

Selenium enables automated test runs on various browsers and operating systems, but the bottleneck is in its ability to execute multiple tests swiftly. Due to resource constraints, tests are carried out in a specific order. However, employing parallel testing can overcome this, provided there are enough resources.

Using a Selenium grid combined with either a device lab or an external cloud tool such as CrossBrowserTesting enables parallel testing. This capability allows for multiple tests across various configurations to run concurrently, effectively cutting down the overall time required for automated tests and expanding the range of configurations available for testing.

6. Limited Reporting

Even though Selenium significantly enhances automated testing, its inherent limitation as an open-source tool restricts robust reporting features. To augment Selenium-based testing, pairing it with a third-party tool such as Cross Browser Testing proves beneficial. This external tool can capture browser screenshots and seamlessly share reports via integrations like Slack or HipChat. Alternatively, you have the option to establish a framework that generates an output folder post-test, containing comprehensive reporting data including errors, execution times, and test pass/fail status.

7. Flakiness

Tests are considered flaky when they exhibit inconsistency in their outcomes upon repeated runs, intermittently passing or failing. Test flakiness can stem from various reasons.

One instance involves validating a dynamic UI element that occasionally delays appearing on the screen. Sometimes, it promptly displays, while other times it takes longer, resulting in the test marking it as a failure by the time it verifies. Analyzing the elements within your Selenium tests can pinpoint the causes behind unstable builds, allowing a direct approach to address these issues.
