User interface (UI) testing is an important part of software development. His goal — ensure convenience and efficiency of user interaction with the software product. In this article, we'll cover the standards, checklists, and essential steps for successful UI testing.

User Interface Testing Standards

General principles

  1. Ease of use : The interface should be intuitive and easy to use.
  2. Consistency : All interface elements should look and function the same on all screens.
  3. Visual hierarchy : Important elements should stand out, and less important — be less noticeable.
  4. Feedback on user actions : Each user action must have a corresponding system response.

Basic standards

  • ISO 9241-210 : Indicates the principles of ergonomics in the development of interfaces.
  • WCAG 2.1 : Accessibility standards that ensure web content is accessible to all users, including people with disabilities.

User Interface Testing Checklist

  1. Visual design
    • Compliance with layout design.
    • Consistency of fonts and colors.
    • Correct display on different screen extensions.
  2. Functionality
    • Correct operation of buttons and links.
    • Navigation compliance.
    • No errors during interaction.
  3. Ease of use
    • Intuitive navigation.
    • Logical arrangement of elements.
    • Availability of hints and error messages.
  4. Availability
    • WCAG 2.1 compliance.
    • Checking with screen readers.
    • Availability of alternative text for images.
  5. System feedback
    • Speed ​​of reaction to user actions.
    • Informativeness of messages.

Steps for user interface testing

1. Preparation

  • Analysis of requirements : Read the interface requirements.
  • Creating a test plan : Determine which aspects will be tested and which tools will be used.

2. Execution of tests

  • Manual testing : Check each interface element manually.
  • Automated testing : Use automation tools to validate large volumes of data.

3. Evaluation of results

  • Error analysis : Determine what problems were found and how critical they are.
  • Feedback to developers : Send a test report.

4. Correction

  • Bug fixes : The developers make the necessary changes.
  • Retesting : Check for fixed items.

5. Completion

  • Documenting the results : Save all test results for future analyses.
  • Product release : If all tests pass, the product is ready for release.
