What Is Web UI Testing?

API testing focuses on the functionality of application programming interfaces (APIs), while web UI testing evaluates the user interface and overall user experience of a web application. API testing involves testing the communication between software components, while web UI testing assesses the application’s graphical user interface.

Web UI testing can be automated using tools like Selenium, which allows the creation of scripts to interact with web elements, simulate user actions, and validate the behavior of web applications.

Selenium is a popular tool for web UI testing. It supports multiple programming languages, provides a wide range of features, allows the automation of web browsers for testing web applications, and can be supplemented by tools like Parasoft Selenic.

Best practices for automated web UI testing include using a robust testing framework (e.g., Selenium), creating maintainable test scripts, incorporating assertions for validation, and running tests in diverse browsers.

Challenges in web UI testing include handling dynamic content, achieving cross-browser compatibility, ensuring test repeatability, and dealing with asynchronous operations.
