Top Automation Tools for Large-Scale Software Testing

Several tools are designed to facilitate automated testing in large-scale software projects. These tools vary in functionality, compatibility, and ease of use. Some of the most popular tools include:

• Selenium: A widely-used open-source tool for automating web applications. Selenium supports multiple programming languages and browsers, making it suitable for diverse testing environments.
• JUnit: A popular testing framework for Java applications that provides a simple way to write and run repeatable tests.
• TestNG: Inspired by JUnit, TestNG is designed to cover all categories of tests: unit, functional, end-to-end, and integration testing.
• Appium: An open-source tool for automating mobile applications across different platforms, including iOS and Android.
• Jenkins: A widely used continuous integration tool that supports automated testing and deployment processes.
