Selenium Test Automation Best Practices

Web-applications are growing more sophisticated as digital technologies continue to progress. As a result, QA engineers will face additional problems as they must conduct complete testing of new features across platforms.

Keep in mind that in today’s competitive world, creating a faultless user experience is a requirement for any website to succeed.

QA engineers may now reduce manual testing by using trusted and well-established open-source solutions like Selenium. They also make it possible to run extensive tests more quickly. To get the greatest results from Selenium tests, however, one must be well-versed in the appropriate best practises.

Selenium Automation Best Practices

  1. Using the Correct Locators

QAs must be adept in employing various locator strategies in order to test the desired web parts of a particular application. After all, the tests will fail if the test scripts are unable to recognise the relevant parts.

The first step in automating inputs to a login page’s Username and Password boxes is to locate those text fields. The login process will fail if the script cannot locate the Username and Password fields.

To learn about the numerous ways to locate web-elements and which locators are most suited for specific situations, read our extensive Selenium reference on Locators.

  1. Page Object Model Implementation

With ever-increasing client demands, a website’s user interface will inevitably adapt as new updates are implemented at regular intervals. Locators pertaining to certain UI elements, of course, change as well. This necessitates QAs creating additional test cases for the same page, which can be time consuming.

The Page Object Model design pattern can be used to create test scripts to address this. Each web page is treated as a class file in this design paradigm, and each class file contains related web elements. This strategy reduces code duplication while also making test maintenance easier. QAs can also reuse existing code with only minor modifications.

  1. Running Selenium Tests on Real Devices

Although there are numerous emulators for Selenium testing across platforms available on the internet, executing tests on real devices makes a significant impact.

Emulators are software applications that simulate a device’s capabilities. They’re better for testing code changes early in the development process. Furthermore, emulators for each device-OS combination may not be accessible, making testing on desired combinations much more difficult for QAs.

Only when websites are tested in real-world scenarios can accurate results be expected. This allows teams to find as many bugs as possible before releasing a stable application.

BrowserStack, a cloud-based platform with a Cloud Selenium Grid of 3000+ real browsers and devices, is a good example of how teams may use cloud-based platforms.

  1. When a test fails, take screenshots.

Selenium programmes will inevitably fail at some point in the future. Finding out why the failure happens — a flaw in the AUT or a code error – is a big challenge in this regard.

Set up the test infrastructure to take screenshots whenever a failure happens to address this. This will make investigating and identifying the cause of test failure much easier, saving time and effort for testers.

The Cloud Selenium Grid from BrowserStack allows testers to snap screenshots automatically during Selenium tests without needing to do it manually.

  1. Use the Browser Compatibility Matrix

To begin with, narrowing down a list of browsers (and browser versions) and operating systems to conduct automated tests on is a difficult undertaking. It is suggested that you utilise a browser compatibility matrix to complete this assignment.

A browser compatibility matrices gathers information from a variety of sources, including browser, device, and OS usage statistics, product analyses, target audience preferences, and so on. The test coverage is thus limited to a certain set of browsers and devices. It essentially limits the scope to the most relevant browser-OS pairings, making the process easier to manage.
