Which of the following tools is commonly used for automated user interface testing?

Selenium is a widely recognized tool specifically designed for automated user interface testing. It enables testers and developers to write automated tests for web applications across various browsers and platforms. Selenium supports multiple programming languages, such as Java, C#, and Python, which makes it versatile and accessible for integration into different testing environments.

The primary function of Selenium is to interact with web elements, simulating user actions like clicking buttons, filling out forms, and navigating pages. This capability is essential for ensuring that web applications behave as expected from an end-user perspective, making it a fundamental tool in the realm of UI testing.

Other tools mentioned have different purposes: JIRA is a project management tool used for tracking issues and bugs, Git is a version control system for managing code, and Jenkins is primarily a continuous integration and continuous delivery (CI/CD) tool used to automate the building, testing, and deployment of software applications. Thus, while all of these tools play vital roles in software development and testing, Selenium’s focus on automated user interface testing distinguishes it as the appropriate choice for answering this question.
