Testing is a critical part of the responsive web design process. The purpose of using a responsive layout is to make the website useful on any type of device, but without extensive testing it’s not possible to know for sure how the site is behaving in different situations. Fortunately, there are a number of different tools and resources available that can help you to test your responsive designs.
