Introduction
User experience and functionalities define the success of an application or software. Whether it's a website, web application, or mobile app, users expect easy-to-use products with no broken links or glitches. This is where UI testing comes in.
UI testing, or user interface testing, is a process in which every click, swipe, and scroll is checked by a tester or DevOps engineer to deliver a flawless experience for the end user. UI testing tools automate user interface testing, making the process faster, scalable, and error-free. These automated UI testing tools have become vital to projects with continuous delivery and continuous integration.
What are UI testing tools?
UI testing tools are automated tools that validate how users interact with software or applications. They test visual elements like buttons, clicks, scrolls, icons, menus, input fields, and more across various browsers, operating systems, and devices.
These UI testing tools ensure your applications look good and work right. UI testing helps detect alignment issues across browsers or devices, broken links or frozen buttons, unexpected changes after adding a new feature or software update, and inconsistencies in user experience across environments.
While UI testing can be done manually, automated UI testing tools are becoming the industry standard due to their speed, accuracy, and scalability.
Practical example of how UI automation testing tools work
Imagine managing an online store or a healthcare app where you want to ensure customers or patients can complete their purchases or make appointments smoothly. A UI testing tool will help you automate your test cases by recording actions that simulate the user journey, such as selecting an item, choosing the size or quantity, adding to cart, entering shipping and billing details, and making payments. If there are any discrepancies in the process, such as a button not working, disappearance of form fields, or inconsistencies after an update, the automated testing tools capture them and then send them to the developer to fix.
Manual vs automated UI testing
Manual UI testing involves a tester physically testing each visual element. Though this is useful for exploratory testing, it has limited scalability, and is slower and more expensive than automated UI testing.
Here’s a closer comparison between manual and automated UI testing:
