How To Use driver.FindElement And driver.FindElements In Selenium C#

One of the essential parts when performing automated UI testing, whether using Selenium or another framework, is identifying the correct web elements the tests will interact with. However, if the web elements are not located correctly, you might get NoSuchElementException in Selenium. This would cause a false negative result because we won’t get to the actual functionality check. Instead, our test will fail simply because it failed to interact with the correct element.

13 Best Test Automation Frameworks: The 2021 List

Automation frameworks enable automation testers by simplifying the test development and execution activities. A typical automation framework provides an environment for executing test plans and generating repeatable output. They are specialized tools that assist you in your everyday test automation tasks. Whether it is a test runner, an action recording tool, or a web testing tool, it is there to remove all the hard work from building test scripts and leave you with more time to do quality checks. Test Automation is a proven, cost-effective approach to improving software development. Therefore, choosing the best test automation framework can prove crucial to your test results and QA timeframes.
