What is UI Testing?

UI testing is the process of testing if the visual elements of your application function as expected. It involves verifying buttons, menus, forms, and other interactive components. By performing UI testing, you ensure users can interact with your app smoothly without encountering bugs or glitches.

Why is UI Testing Important?

Prioritizing UI testing in your development workflow is important for your user satisfaction and retention rates. Here are the most important benefits:

  • Better User Experience: If users encounter problems while interacting with your app, they will likely leave and never return. This can result in lost revenue and damage to your brand's reputation. UI testing helps stop these issues from happening.
  • Higher Product Quality: A good app or website should not only work well but also look good. UI testing finds bugs that affect users directly and provides insights to improve the overall design. Fixing issues before the final release saves time and resources. It also ensures that your app meets industry standards and regulations.
  • Consistent Branding and Design: As the part of the app users see, the UI must follow design guidelines to reflect the brand's values. While looking for UI issues, testers can also suggest ways to improve design consistency throughout the app.
  • Increased Usability and Accessibility: Usability is about how easy the app or website is to use, while accessibility is about how user-friendly it is for people with disabilities. Both aim to make the app more intuitive and inclusive.

Include negative scenarios, like entering letters in the numbering field and seeing what happens. You should develop standard operating procedures (SOPs) to standardize processes and make your team's software testing more efficient over time. For this step to be tested, you can use a test script to cover scenarios when:

  • User enters a valid username and password
  • User enters a valid username and an invalid password
  • User tries to copy the password from the password field
  • User tries to paste the password into the password field
  • User resets the password
  • User clicks the “Forgot password” or “Help” button

Note: Some projects might require starting UI testing by checking the prototypes built on wireframe tools before your developers even start developing. However, other projects may test the user interface only after a working application is ready.

4. Choose Tools

Choosing the right UI testing tools and methods is crucial for executing a successful test plan. Using the wrong tools and methods can make you think you're making progress when you're actually wasting time and resources.

Use a bug-tracking tool like Jira to manage and track your test cases and issues. For automation testing, use a tool like Selenium to create and run test scripts efficiently. And if you need manual testing or a combination of manual and automated testing, GlobalApp is the solution to go. When picking testing tools, consider the following:

Automated tests use scripts to interact with the app and check if everything works as expected.

Note: Document your test results with detailed steps, screenshots, or screen recordings to help your team understand the context.

Once you’ve done this, it’s time to analyze your findings and draw conclusions.

6. Analyze and Report

You should create reports to document the testing process and results based on your testing, screenshots, screen recordings, etc. Gather your findings and report any bugs found during testing. To keep everything organized and in a single place, you can use a defect tracking or project management tool, which will help you document everything you need to fix. In your bug report, ensure to include:

  • Steps to reproduce the issue
  • Expected and actual results
  • Screenshots or screen recordings of the problems appearing

These reports will help developers, engineers, and other teams to quickly understand and fix the issues. Check out our guide on how to write a good test summary report.

7. Retest to Validate Fixes

Once the development team fixes the issues, retest the affected areas to make sure the issues are resolved. Also, test-related features often have problems due to code changes to ensure no new bugs appear in this process. For example, after fixing a broken 'First Name' text box, check if the 'Full Name' text box, which depends on it, works properly, along with all the other related fields and boxes.
