In the code snippet shown below, we wait for the web element (with linktext as SITEMAP) to appear on the page. In that environment, it will be wrong to assume that the next test will use Firefox WebDriver (or Chrome WebDriver or any other WebDriver). The subsequent delay of 5 seconds not only elongates the duration of the test cycle but may also cause stability issues with the UI automation tests. You can also refer to the below video tutorial on how to handle Windows and Frames in selenium.

"acceptedAnswer": { Performance testing using Selenium and WebDriver is not recommended, as it is not optimized for doing that task and you might not get the expected results. One of the most critical Selenium best practices is to avoid inter-dependency between different tests in a test suite and separating the specification of what the test is supposed to do from the test execution strategy.
