Challenges faced in Selenium automation

 More companies are attempting to include automation testing into their software development lifecycle as it grows in popularity. Even though automation can speed up the testing process and boost coverage, it can be challenging to get it correctly.

In this blog post, we'll discuss some of the most frequent issues testers encounter while using test automation and offer solutions.

What is Selenium ?

Software testing professionals can build and execute automated test scripts on top of the well-known open-source Selenium test automation tool or platform. Additionally, the Selenium user interface enables the development of test scripts in a variety of well-known programming languages, such as Ruby, Node JS, Python, Java, C#, PHP, etc.

What is Selenium Used for?

Businesses can use Selenium testing to validate the functionality and compatibility of online apps across a variety of browsers. Selenium is a collection of software tools that individually address a company's unique QA testing needs for distinct technology implementations.

You can write test scripts using Selenium in the programming language of your choice. Then, it enables its execution on a browser instance in any preferred device, whether a smartphone, tablet PC, or physical computer. This allows testing teams to avoid spending the numerous hours of testing time necessary to manually examine each module of an application in a real run-time setting separate from the development ecosystem.

Commonest Selenium Challenges

• Flakiness

• Limited Reporting

• Dynamic Content

• Mobile Testing

• Pop-up Windows

• Scalability Issues

• Validating Dynamic Runtime Elements

Flakiness

Selenium occasionally gives shaky testing, which could make findings appear positive or negative when they are reality to the contrary. If there are too many flawed tests, testers can eventually decide to disregard the results, which isn't a great solution either. Unstable builds are usually caused by timeouts, unreliable external services, and insufficient test isolation. You may more quickly identify the root cause of your unstable builds and take prompt action by looking at the Selenium test components.

Limited Reporting

Although Selenium is an open-source tool with limited functionality and reporting support, it will greatly enhance your automated testing skills. The greatest compliment to Selenium-based testing for this is a third-party tool like CrossBrowserTesting, which can snapshot browsers and give findings via connectors with Slack and HipChat. However, you may also configure a framework, such as TestNG, to produce an output folder containing report details after a test, such as issues, execution time, pass/fail count, etc.

Dynamic Content

It's possible that some parts won't be instantly apparent when you visit a website with dynamic loading. This could mean that the content of the website is user-specific and changes depending on the user, that new content appears after a certain period of time has passed, or that new content appears once a user clicks a particular element on the page. Selenium WebDriver features an inbuilt Explicit Wait functionality that lets you define a time to wait before automating an operation in cases where a locator is unable to recognize a new element present at that specific moment. This should hasten the loading of the website and make it more obvious which element has to be clicked.

Mobile Testing

On a desktop computer, Selenium WebDriver can run tests on any browser and operating system, but it has significant limitations when used for mobile testing because it cannot work on native operating systems like iOS and Android. When Facebook opens in Safari on a Mac, for example, Selenium can test it, but not when it opens in Safari on an iPhone 7. The selenium family contains a remedy. Its cousin, Appium, is an open-source test automation framework that uses the WebDriver interface to power native, mobile, and hybrid iOS and Android apps. Appium can be used to test mobile apps instead of online applications.

Pop-up Windows

It might be challenging to automate a simple, prompt, or confirmation alert to accept or close. Furthermore, Selenium cannot test Windows-based alerts since they are an operating system function rather than a browser feature. Web-based alerts can frequently be managed with the switch to function to control the pop-up while maintaining the browser in the background because Selenium WebDriver can handle multiple windows.

A web-based automation tool called Selenium is free to use. Selenium tests are run using Python. Compared to other programming languages, it is much simpler and less verbose. The Python APIs allow Selenium to communicate with the browser.

Scalability Issues

As the application's usage and feature set grow, so do the breadth and coverage of the testing environment. You can run test builds consecutively across many environments using Selenium. However, as the application size increases, it might not be very effective. The software testing phase won't be effectively automated unless testers can run more tests and cover all conceivable scenarios. Scaling issues may therefore eventually have an impact on the general test quality.

Validating Dynamic Runtime Elements

Today, the majority of websites use security measures like captcha to prevent unwanted bot attacks on specific parts of the homepage. End users cannot access them unless they have solved the captcha. Additionally, the Selenium testing environment may not have much control over pop-up messages and notifications that are tied to the operating system. Testing can be challenging as a result, as Selenium doesn't come with a captcha-solving intellect out of the box. Additionally, it can't control OS-related pop-up activity.

Conclusion

Automation tools have been around for a while. They have made it simpler for developers and testers to automate routine tasks that would otherwise be laborious, unpleasant, or just plain boring. As is the case with anything digital, automation is always expanding to suit the expectations of contemporary software development teams. These tools present new challenges for users, such as the limitations of Selenium WebDriver and the challenging technical debt imposed on by test automation, but they also present fresh opportunities for growth.
