How To Test a Responsive Design?
A responsive design tester can consider the following variances for Responsive testing-
Emulators: it is a simulation-based on the web. It simulates how a website or application will look like or function in a mobile device.
The emulator does not serve you with the exact testing facilities.
However, they are a very cost-effective and powerful solution to test a website’s compatibility in different screen size.
Google Dev Tools-Device mode: it consists of a feature known as device mode which includes tools that are very helpful for debugging and testing responsive designs.
It tests your responsive design by emulating various screen resolutions and sizes.
Moreover, it uses a network emulator to evaluate your site’s performance without hindering the operations of other tabs.
The tool inspects and visualizes media queries and simulates device input accurately.

General Rules For Responsive Design Testing

• Never visualize the horizontal bar in the page
• Text included in the website should be properly visible when scrolling
• Pages should be readable and clearly visible in all resolutions
• The important content in the page should be visible in all *breakpoints
• There should be proper padding around the corners
• The font color, size, and style should be consistent for all sort of text
• Shading, gradient, and color should be consistent
• Frames, images, text, and controls should not run into the corners of the screen
• Ensure that the controls, images, and texts are aligned properly
• There should be a suitable clickable area present in the page

Determine the use of your web application. You can take the help of Google Analytics to identify which devices are used by your customers to reach your website.
Furthermore, you should be able to detect the breakpoints and all the elements that will be appearing as you shift from one breakpoint to another.
After this is done, its time you take into consideration the automated tools and emulators and conduct basic checks and functional testing.
Combine the testing with the real device manual testing in the end.

• For the correct and proper testing of a responsive design website, there needs to be perfect coordination between the tester and the developer. The developer must help the tester through creating the necessary conditions as mentioned in the test cases.
• The main content of the responsive website should be visible from every breakpoints. The transition of the website from the desktop screen to the mobile screen size should not affect the main text and other content.
• Responsive design testing only detects major issues. However, you should always remember to test the small features like tapping, swipes, and other finger related issues. Doing so will lead you to better and successful testing.
