UI Testing - The Definitive Guide for 2024

User Interface (UI) testing is a crucial part of software development. It ensures that your application's interface works correctly and provides a good user experience. Without proper UI testing, users might face issues that can lead to frustration and abandonment of your app. This guide will help you understand what UI testing is, why it's important, and how to implement it effectively in your business.

Key Points:

• Understand the basics of UI testing.
• Learn why UI testing is essential.
• Discover steps to implement UI testing.
• Explore tools and best practices for UI testing.

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.

Both automated and manual UI testing have their place in the development process. Combining both methods often yields the best results, ensuring a thorough and effective testing strategy. So, let’s see how to implement UI testing for your business.

How to Implement UI Testing in Your Business

Implementing UI testing in your business is essential for delivering a seamless user experience. Follow these steps to ensure a smooth and efficient process:

1. Define Objectives

To track and be aware that your UI testing is properly done, you need to set the goals and scope of UI testing. This process allows you to create a plan matching the project's overall goals and ensure a thorough product check.

For example, decide how UI testing fits with broader quality assurance goals. The plan should also outline the testing team's roles, the test environment, and the testing schedule.

You might consider adding user behavior analytics tools to your UI testing process to gain insights into user interactions and experiences, which can help inform your UI testing objectives.

2. Select Testing Methods

In this phase, you should decide whether to use manual, automated, or a combination of both tests depending on your needs. So, if you need flexibility within your testing and if your scope of testing is complex but you have time to execute your tests, maybe you should consider manual testing. However, if you’re looking for efficiency and scalability but your scope of testing is pretty simple, automated UI testing might be your choice.

Pro tip:

Global App Testing conducts manual testing with over 90,000 human testers to check the new applications without using any automation tools or scripts. Our process includes:

• Understanding your project requirements
• Preparing test cases
• Reviewing these cases
• Executing the testing, and
• Reporting bugs.

We emphasize the importance of the human touch in finding errors and bugs, especially for Usability and UX testing. This manual testing approach is adaptable, provides human insights, and is suitable for various software types and environments, such as acceptance testing, black box testing, integration testing, system testing, and more.

3. Create Test Cases

Once you’ve chosen your testing method, you must outline possible scenarios and user interactions to identify key UI parts and features to test. Create detailed test cases and ensure to cover each scenario, including what you expect to happen, to ensure software testers check all parts of the specific functionality.

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:

• Ease of use
• Compatibility with your tech stack
• Cost
• Trustworthiness of the software handling your company's private data

5. Execute Tests

Setting up a proper testing environment is vital for accurate results. Ensure your environment mimics real-world conditions as closely as possible. This includes:.

• Hardware Setup: Use a variety of devices to test on different:
  • Devices - like smartphones, laptops, tablets, TVs
  • Browsers - like Chrome, Firefox, and Safari
  • Screen sizes - by changing the window size on your computer
  • Mobile operating systems - like Android and iOS
• Software Setup: Install necessary software testing tools.
• Network Conditions: Simulate different network speeds and conditions.
• User Data: Use realistic data to test user interactions.

Once everything is ready, you can run the tests and record the results. You should have someone on your team, like a QA analyst or engineer, who will manually test the application by acting like a user and looking for problems. 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.
