Visual Testing for Responsive Web Design- What Are the Aspects to Know?


Most of our time is now spent on smartphones, which rule the period in which we live. It is interesting to know that the typical smartphone user uses their device for 4 hours and 30 minutes daily. Given this, there is a good chance that you are also reading this post on a smartphone.

Smartphones come in various sizes and styles, and any of these can be used to access your website by potential clients or visitors. Due to this, it is essential to ensure that your website is aesthetically pleasing and user-friendly, regardless of the platform being used, whether desktop, laptop, tablet, or smartphone. This is where responsive design testing comes to play where using visual testing tools to check for compatibility becomes crucial. Its purpose is to guarantee that your website maintains its visual appeal and functionality across different devices.

What is Visual Testing?

Visual testing is a method used to test mobile or web apps that assesses how the programme’s user interface (UI) or graphical user interface (GUI) looks and behaves visually. Its main goal is to guarantee that the application’s visual components—such as colours, pictures, fonts, and layouts—are consistently shown across various mobile devices, applications, and browsers.

The capacity of a visual testing tool to confirm that the user interface (UI) of a built product is displayed as intended for consumers is what gives it its significance. It offers several key benefits, including:

  • Identifying defects or issues in the UI interface
  • Detecting variations in the UI compared to baseline snapshots
  • Creating specialized visual test cases
  • Identifying visual bugs across different browsers

Moreover, visual testing provides an efficient and effective means of testing mobile or web applications, enabling testers to identify visual defects and inconsistencies that could potentially impact the application’s user experience and overall usability.

What is responsive design?

Responsive web design (RWD) is a technique used to adapt a webpage’s layout to different screens and screen sizes, effectively utilizing the available screen space. Implementing responsive web design involves applying various concepts, with one of the key elements being the fluid grid. 

In responsive web design, each targeted screen size is referred to as a breakpoint or viewport. Typically, a website will have separate viewports designed for mobile, tablet, and web. By incorporating responsive design principles, web developers ensure their web pages can seamlessly adjust and optimize the layout for different devices and screen dimensions.

Impact Of Visual Testing on Creating a Responsive Design

Visual testing is a crucial aspect of responsive design testing, as it ensures consistency in the user interface (UI) across different devices and browsers. It addresses potential issues such as variations in colors or discrepancies in the appearance of elements on various platforms. Resolving these inconsistencies is essential before launching an app or website to the public, as even minor visual differences can impact the user experience, trust and adoption. 

Typically, automated visual testing serves as the initial step in responsive design testing. Testers compare the intended UI design across different screen sizes, devices, and operating systems to verify its look and feel. Automated visual tests are often utilized in the testing community because they are quicker and less likely to overlook minute changes than manual visual tests. To guarantee that the visual testing tool you choose is appropriate for the work at hand, you need to consider several specific factors.

  1. Device and Browser Support
  2. Accessibility 
  3. Automated testing
  4. Integrations and Supported Framework
  5. Snapshot Stabilization
  6. Budget 

When it comes to mobile apps, visual testing proves to be the most accurate and efficient method for evaluating UI elements. By implementing a visual testing strategy, important questions regarding the app’s user interface can be addressed, such as:

  • Does the app’s navigation and UI elements appear intuitive when displayed on mobile devices?
  • How are visual changes tracked and reviewed?

Through visual UI testing, quality assurance (QA) teams can examine whether UI elements possess the intended characteristics across different properties. These properties include color, position, and frame, among others. This allows for a comprehensive assessment of whether the UI elements deliver the desired value.

What do we need to test?

Responsive design testing requires a thorough examination of every element and component of a website or app to ensure consistent performance across devices. A reliable, responsive web design tool simplifies testing and facilitates comprehensive assessment. The success of a website or web app heavily relies on meticulous, responsive design testing, encompassing various components such as text, image optimization, and validation of visual elements, all of which contribute to delivering a consistent user experience.

Key considerations in responsive design testing include:

  • Content Style and Alignment: Proper alignment and consistent content display are essential. Maintaining consistent text size ratios guarantees uniform style and alignment across digital platforms.
  • Media Consistency: Images should be visible and provide contextual information across all channels. Proper optimization of images and videos based on device sizes is crucial to prevent overlaps with text or other visuals, ensuring clear communication and a clean visual experience.
  • Menu Bar: On smaller screens, collapsible menu bars enable easy navigation. Specific devices may cause compatibility issues, leading to misalignment between call-to-action buttons, text, and other elements. Testing on real devices and across various browsers with different configurations helps identify and resolve such visual issues.
  • Mobile Device Orientation: Mobile devices and tablets offer the flexibility to change screen orientation. It is crucial to optimize web design to accommodate different orientations and adjust content accordingly. Failing to provide a satisfactory viewing experience in different orientations can lead to user frustration and a negative experience.

Summing It Up

Visual testing is crucial for creating a positive user experience. It ensures user-friendly applications and eliminates visual inconsistencies impacting the user journey. As online presence grows in importance, automated visual testing becomes more automated, faster, and essential for enterprises.
