Screenshots in Selenium play a vital role in enhancing the effectiveness and efficiency of testing, troubleshooting, and communication during the software development process.
Why is Screenshot required in Automation testing?
As we know, one of the primary purposes of automation testing is to reduce manual effort. Therefore, the use of a screenshot captured during automated test runs becomes very useful. You would not want to monitor your application every time the tests are executed. The script can take a screenshot, which helps check the application functionality/state when the test execution completes. Screenshots also help you when your test case fails so that you can identify what went wrong in your script or your application.
They also help to distinguish whether the failures are due to application failure or due to the test script failure. The following scenarios will be the significant use cases, where a screenshot will be handy to debug the automated test cases failures caused:
When application issues occur
When an assertion failure occurs.
Also, when there is some difficulty in finding a web element on a page.
Where there is a Timeout in finding a web element on a web page
