How to Capture Screenshots of Specific WebElements using Selenium 4

All the activities in the STLC (Software Testing Life Cycle) process are accomplished in an organized and structured way. Needless to say that Test Execution is one of the phases in the Software Testing Life Cycle, which is the process of comparing the expected and the actual results. In the Test Execution phase, the testing is performed based on the test plan and the test cases. During the Test Execution, the Test Engineer should document the test results and log defects for the failed test cases. It is advised to take the screenshot when the user executes the test script. These screenshots provide a proof that the test functionality has been tested or not. Also, if any test case fails, then this screenshot will help the user to debug and identify the test failure.

Why Take Selenium Screenshots in the First Place?

Automated testing has become a significant part of the entire software testing lifecycle. The ability to execute a script and get results without interference or monitoring has resulted in significantly higher levels of efficiency in much shorter timelines. However, the whole point of automated testing is defeated if one has to re-run an entire test every time a script fails. If something goes wrong, it helps not just to have the bug pointed out in the code, but also have some visual representation of the exact anomaly. Similarly, a tester has to check if the flow of the application is as intended. Once again, visual representation helps in this case.

This is where Selenium screenshots come in. Using Selenium, it is possible to take the screenshots automatically during the test execution. As you know, capturing entire page screenshot is very easy task but if you want to capture screenshot of specific web element then you will feel that it is a little challenging.

Here is a step-by-step guide on how to take screenshots of a specific web element using Selenium 4 along with a simple use case.

Being able to take screenshot is a huge plus point in Selenium. When working with automated tests using Selenium, we often need to take a screenshot of a web page or part of a web page. This can be useful, particularly when debugging test failures or verifying that your application behavior is consistent across different browsers. In this quick tutorial, we look at ways in which we can capture screenshots using Selenium 4. To put it in a nutshell, if the automation engineer finds a specific web element, then it’s possible to capture the screenshot of that element in Selenium 4. Hope this could help you to gather some useful information on capturing screenshots of specific web elements using Selenium 4.
