The primary use case we use this solution for would be to test our Marketing websites.
With our websites, the users' needs are always expanding and growing. There are many times we are adding and taking away content, as well as modifying existing content and page layouts. Different campaigns are created with tracking measures and parameters that are validated for company use and reporting.
It is important in these cases that we are able to run tests on different devices and browsers with clear cookies and session storage to be able to see any differences and provide clear accurate results.
