2. What is UI Testing? User Interface testing, also known as UI testing or GUI testing, tests the application’s visual elements to validate proper functionality and expected performance. It ensures that UI functions and application components have no defects, such as icons, radio buttons, text boxes, toolbars, color, fonts, checkboxes, windows, and menus. The primary aspects of UI testing are functionality, performance, usability, compliance, and visual design of the software application to make sure the application works successfully and satisfactorily. © 2023 HeadSpin.

3. Why is UI testing important? UI testing checks how the application handles user actions using input devices like keyboard and mouse and whether the visual elements are working and displayed correctly. In addition, it ensures the efficient and accurate performance of the software application’s UI so that end-users adopt it quickly and successfully. A faulty UI does not meet user expectations. It is the only way to interact with users, and malfunctioning UI may damage the brand or product adoption. Therefore, it is vital for organizations developing software applications to carry out UI testing before releasing it to production. © 2023 HeadSpin. All Rights Reserved

5. 1 1 Sprint-level regression testing - This type of test emphasizes on executing the test cases that have emerged only after the last release. Regression Testing Regression testing consists of repeated testing of the existing features of any tool, application, or system as it receives new upgrades. 2 End-to-end regression testing - This type of test focuses on covering tests on all core functionalities present in the product. © 2023 HeadSpin.

6. 2 1 Requirements-based functional testing: This method contains instructions on validating the software system's functional aspects. Functional Testing The functional or requirement specifications help define what QA engineers consider acceptable while running functional tests. 2 Business scenarios-based functional testing: This method contains instructions on validating the software system based on business scenarios. © 2023 HeadSpin.

7. 3 1 Structural Testing Technique: The structural testing method is a test that evaluates the structure of a software application. This test is often known as white box testing. Unit Testing Unit testing is the cornerstone of software application development, as it involves the testing of individual components of a software application. 2 Functional Testing Technique: The functional testing method is a test that aims to verify that each app feature works as per the requirements of the software. Error-based Testing Technique: The error-based testing technique is an experience-based testing technique where testers use their experience to guess the problematic areas of the software application. 3 © 2023 HeadSpin.

8. 4 1 Load Testing: This is done to detect the behavior of the application under peak load and normal load conditions. Performance Testing Mobile application performance testing is done in a simulated environment to determine the application’s performance and forecast the end user’s experience after launch. 2 Capacity Tests: This is similar to stress tests and quantifies the number of users and transactions that can be supported before the application fails. 3 Stress Testing: Stress testing is conducted to check whether the application will withstand the failures or become vulnerable. If it is the latter, then to what extent and under what conditions is something that will be determined. © 2023 HeadSpin. All Rights Reserved

9. 5 1 Alpha Testing: Alpha testing helps validate the functionality of a new app. The internal staff carries out alpha tests early on in the development process. The goal is to identify and eliminate defects before releasing the software. 2 Beta Testing: The clients/customers/users run beta tests. They perform these tests in real environments before the organization officially releases the product into the market. Acceptance Testing Acceptance testing is used to check how end users will respond to the final software product. Usually, this is the last type of testing used before a software/application is released. Acceptance testing helps check the app's functionality concerning business requirements and assess if it's ready for delivery. 3 Operational acceptance testing (OAT): It helps system administrators ensure their systems continue to work well. They test the backup and restore features, user management, maintain the software © 2023 HeadSpin. All Rights Reserved

10. The GUI testing has different approaches: Manual testing It creates graphical models describing systems’ behavior. It generates highly efficient test cases to understand the system performance in detail. The model-based testing follows steps discussed below: • Model building for the system • System input determination • Verification of the expected output • Test execution • Checking and validating system output vs. the expected output. © 2023 HeadSpin.

11. Benefits of UI Testing Other than ensuring accurate working of the application’s UI, UI testing offers various benefits, as discussed below: Cost reduction Automated testing is inexpensive compared to manual testing Automated UI testing removes human errors and makes performance potentially more valuable and creative than manual testing Opportunity cost reduction Speed UI test automation is faster in orders of magnitude than human testers. Automated UI testing provides consistency and reproducibility compared to manual human testing. Reproducibility and consistency © 2023 HeadSpin. All Rights Reserved

12. Best Practices for UI Testing Though there is no ideal user interface testing method available, some of the best practices for UI testing are as follows: • TUI testing is valuable, but one should never rely entirely on UI testing. Testers should always tally the input and output of the UI testing. • The tester should investigate particular test cases required in different browsers instead of applying all possible tests in all target browsers. • The naming convention is necessary to make specific tests easier to understand and track immediately whenever required. © 2023 HeadSpin.

13. Checklist for your first test UI component functionality and its design are multi-faceted. It needs attention to detail, good judgment, and defined scopes. • Positioning, length, size, alignment, and width of all UI elements • Data entry in fields for numbers, texts, special and invalid characters • Software functionality execution • Data type errors • Navigation elements • Table scrolling • Progress bars • Error logging • Shortcuts and menu items • Action buttons © 2023 HeadSpin.

14. Conclusion UI testing is carried out using automated tools and frameworks. UI testing tools are Selenium, QTP, Ranorex, and Cucumber. Whereas Ui testing framework examples include Serenity, Robot Framework, Cypress, TestProject.io, Sahi, and so forth. Conclusively, UI testing has become crucial for today’s software development, and thus one needs to follow specific guidelines while carrying out UI testing.
