Website UI Testing Checklist

Testing focuses on defect detection, Quality Assurance focuses on defect prevention.”


Testing is the best way to make sure your website and mobile app are as attractive as possible. Quality is a critical parameter in ensuring industry growth and retention.

Technology is all about testing. User interface testing is crucial to make a lasting impression with the target audience. Visual testing plays a critical role in quality control and is required by industry leaders before launching new products or updating features.

Visual Testing vs. Functional Testing

Visual testing involves identifying and fixing errors or bugs that are displayed on the screen. These tests are performed by developers in both the development and functioning phases. Visual testing is not the same as functional testing, since it occurs after a few front-end modifications. Their rectification is therefore based on a different checklist.

UI Testing Checklist

Functional testing is the only way to build the visual appeal of any digital platform. Once you have a clear understanding of the requirements, we recommend that you review our 10-point UI Testing checklist. It will help streamline your brand’s visual requirements.

1. Basic Functionality of the Application

Although functional testing is not the best way to understand visual bugs it can help bring them to the forefront. It should include transaction of messages, app memory customization and biometrics.

2. UI Compatibility Across Platforms

You will need to test your app on different screen resolutions and native apps on iOS and Android in order to ensure UI compatibility. Allows you to easily test any combination of browser-device/OS. Get a Free Website Testing on Different Browsers & Devices

3. UI Compatibility across Screen Sizes

There are no two devices screens the same. With the variety of mobile devices on the market, it is imperative that you conduct UI responsiveness testing using the most popular devices among your target audience.

This issue can be addressed by optimizing your user interface for most frequently used devices in landscape or portrait modes.

With checkyourconnections free Responsive Design Test, can test website responsiveness on 3000+ devices and browsers as well as the most popular ones in your market.

4. Performance and Scalability

A mobile app that is easily scalable will deliver seamless performance. You must test the UI using various traffic levels, load levels and install/uninstall durations in order to ensure smooth operation.

Parallel Testing allows you to leverage automation testing by running the same tests in multiple environments, real device combinations and browser configurations. This will allow you to test multiple interfaces simultaneously, while reducing time and resources.

5. Mobile App Accessibility

In mobile app UI testing, accessibility and responsiveness are both important. This phase includes screen reader, speech recognition and font size.

6. Geolocation Testing

Global expansions increase the need for quality testing. Geolocation testing is required if your mobile app requires the configuration of multiple currencies or languages. IP geolocation allows you to simulate user behavior from different locations using secure, private IPs that are hosted in 45+ countries worldwide.

7. Color Checks

For a unique look, pay attention to the color scheme in the web app. Make sure the hyperlink is using the suggested color.

8. Typography Errors

Take care to assess text alignment, spelling mistakes, font sizes, upper/lower cases, and so on.

9. Navigation speed

After the web app has been loaded, check the loading speed for the header menu. Check if lazy loading is enabled there. To ensure a fast user interface across all major browsers and device combinations.

10. Alignment of Images

The essence of a web application’s overall appearance is its graphic alignment. Make sure images are properly displayed, especially in the header and slider banner.

Significance of visual testing

Your first interaction with your business will be through color scheme, text, background, x,y coordinates and background. The platform’s credibility will be questioned if there is any error or overlap. Visual testing will make a lasting impression on viewers.

You might have an app for food delivery that has three panels. These panels are for users, restaurants and admin. Two distinct sets of users will be available, so you need to monitor their use and check the screens. Automated visual testing scans the entire app setup to identify areas for improvement and ensures zero hiccups.

Visual Testing – Manually or Automatically?

Many automated functional testing tools are not suitable for visual testing. Numerous developers have tested these tools to identify graphical problems but failed.

Manual visual testing, on the other hand is a time-consuming and exhausting task for both developers and testers.

Manual Testing may sound like an economical way to ensure quality, but there are some drawbacks and challenges.

  • Manual visual testing must be performed on multiple browsers with different screen sizes and devices.
  • Many errors can be difficult to spot especially when using a mobile device to test the platform.
  • Each rendering session will result in multiple minor bugs that nobody can easily spot.

Manual testing does not have to be tedious. Manual testing isn’t always an option if you have many web pages to test within a given time frame.

Limitations on Visual Testing of Emulators/Simulators

  • It does not allow for the evaluation of performance, battery usage, or other hardware-related aspects. Functional testing is more applicable to virtual testing.
  • The authentic interface of real devices can also reveal more bugs, which leads to increased testing speed.

What is better for visual testing?

Visual testing is not affected by the device type, according to most developers. What if it does matter? What if it does? Can you expect the same results after performing visual tests on emulators and real devices? It is unlikely! It’s not!

Although it may not be possible to test your application on both types of devices, strict deadlines might prevent you from doing so. However, this has its advantages. Visual testing on emulators and simulators reduces the need for a lab. However, visual testing on a actual device cloud is not ruled out. Emulators are not able to perform quality checks for voice or text commands.

Percy Visual Testing on Real Devices

Percy is a visual testing tool that simplifies quality control and streamlines the process of making changes. This is a visually-strengthening tool for visual testing that you can set up in the CI/CD pipeline to track down any potential bugs and edit the interface.

Percy Visual Testing Tool: How to Use It

  • This automated visual testing tool can be used in just three steps. It can be integrated directly into the application or within an automation framework.
  • To capture comparison photos of the end-to-end process, run the test. These images highlight areas that have bugs and need to be fixed.
  • This tool is flexible and can be used to alleviate team-based testing. It allows users to report errors via comments or notifications.

What does Percy bring in for developers?

  • Flawless – Percy can take DOM snapshots and capture every visual component that has to be modified.
  • Tailored control – This allows developers to create a customized setup that allows them to easily make changes to different browsers based on screen sizes.
  • No prior setup – Percy allows developers to freeze CSS animations, and other dynamic elements in the user interface without the need for any testing.

To Conclude

The user interface testing is the foundation for usability of your web apps, websites, and mobile applications. When performing a comprehensive quality test on your platform, be sure to refer to the above checklist.

Percy from checkyourconnections can be used to reduce the time and effort required for manual visual testing. You can now get rid of the tedious task of setting up UI modules and network requests. You can also control each dynamic element of your UI to make any necessary changes. Automated visual testing allows you to produce visually flawless applications quickly and maintain consistency across the entire UI.
