Before we indulge ourselves in the challenges faced in Selenium automation, we must understand the basic concept of selenium automation testing.
When we talk about automation testing, Selenium is a common tool. The reason behind it is that Selenium is an open-source automated testing tool for validating web applications across multiple browsers and platforms.
Since Selenium WebDriver supports various browsers, including Chrome, Mozilla, Firefox, Safari, and Internet Explorer, it allows you to automate browser tests across these browsers easily.
We can write selenium Test Scripts in various programming languages. The most common ones are Java, C#, and Python, which is the most prominent reason for choosing Selenium for automated testing.
Recurrent Challenges of Selenium Automation Testing
Now comes the part where we will highlight what are the challenges faced in selenium automation testing and discuss ways to fix them quickly.
1.Testing Mobile Apps
We can do the testing on any operating system and web browser on the desktop, but we cannot test mobile apps with Selenium alone. For example, you can use Selenium to try the version of Facebook you open in Safari on your Mac, but not the one you open in mobile Safari.
Quick fix: Using the WebDriver protocol, Appium can handle iOS and Android native, mobile, and hybrid apps that may fix this issue.
2. Pop-up Windows
When a prompt, simple, or confirmation alert appears, automating it to accept or close is the most challenging task. Since Windows-based alerts are part of the operating system rather than the browser, they are beyond Selenium’s capabilities.
Quick fix: Web-based alerts can usually be handled with the switchTo technique to control the pop-up while keeping the browser in the background since Selenium WebDriver can run multiple windows.
3. User-Specific Web Pages
Some web pages are user-specific. Depending on the user, these user-specific pages load different components. In response to the previous action, some elements may appear.
When you choose a country from the country drop-down, cities associated with that country appear in the cities drop-down. During runtime, the Selenium script may miss the aspect.
Quick fix: To solve this particular problem, we can use explicit waits in the Selenium script to give elements enough time to upload and find the element. You can also use Test Project’s adaptive wait feature to ensure that your tests are not flaky.
Although Selenium allows you to test on any browser or operating system, it is limited to how many tests it can run in one time and how quickly it can do so. You can only run one test after another without a Selenium grid.
Selenium Grid allows you to scale your test process by using remote Web Drivers and enables you to run tests in parallel. However, you might not be able to test your web application on various browsers and operating systems. At a time, you can only run tests on one OS and browser.
Quick fix: To test your apps across different OS and browsers at the same time, you can use cloud-testing solutions
5. Visual Testing
Selenium WebDriver lacks visual testing capabilities, critical for testing beyond functionality and evaluating overall user experience.
Quick fix: Outsourcing visual tests to a third-party screenshot tool that integrates with Selenium is the most effective method. For mac pc you can use mac screenshot software Cloudapp. Its simple and easy to use.
Although Selenium automated testing is hard to execute, it is undoubtedly the king of web testing.
While Selenium automated testing has challenges, but it can undoubtedly facilitate with rapid identification and resolution of issues in an app’s codebase, the challenges are not without their own set of difficulties.
As a result, additional tools or methods must be considered and implemented as needed.
