UFT (Unified Functional Testing), formerly known as QTP (QuickTest Professional), is a commercial test automation tool developed by Micro Focus. It is primarily designed for automating functional and regression testing of web, desktop, and mobile applications. On the other hand, Selenium is an open-source test automation framework mainly used for web application testing. While both tools are used for test automation, they have different features, advantages, and use cases.

Here’s a brief comparison of UFT and Selenium:

UFT (Unified Functional Testing):

1. Commercial Tool: UFT is a commercial tool, which means you need to purchase licenses for its usage.

2. Multi-Platform Support: UFT supports various application types, including web, desktop, and mobile applications. It also supports various technologies like .NET, Java, SAP, etc.

3. Object Recognition: UFT uses a technology called Object Repository to identify and manipulate objects in the application under test. It provides a user-friendly interface for managing object properties.

4. Scripting Language: UFT primarily uses VBScript as its scripting language, although it also supports JavaScript.

5. Record and Playback: UFT offers a record and playback feature, allowing testers to record interactions with an application and then generate test scripts automatically.

6. Integrated IDE: UFT provides an integrated development environment (IDE) for test script creation and execution.

Selenium:

1. Open-Source: Selenium is an open-source framework, and its core libraries are free to use.

2. Web Application Testing: Selenium is mainly used for web application testing. It provides WebDriver, which allows you to automate interactions with web elements and web browsers.

3. Cross-Browser Testing: Selenium is well-suited for cross-browser testing, as it can automate actions in multiple web browsers like Chrome, Firefox, Edge, etc.

4. Programming Language Support: Selenium supports multiple programming languages, including Java, Python, C#, Ruby, and JavaScript. This gives you flexibility in choosing the language you’re most comfortable with.

5. Community and Ecosystem: Selenium has a large and active community, which means you can find a wealth of resources, plugins, and integrations to enhance your test automation efforts.

6. Integration with Testing Frameworks: Selenium can be integrated with various testing frameworks like TestNG, JUnit, and others for better test organization and reporting.
