Testing

Software testing is a crucial process in the software development lifecycle that ensures the quality, functionality, and performance of applications. It involves identifying defects, verifying that the software meets user requirements, and ensuring reliability before deployment. Testing can be categorized into manual and automated testing, with tools like Selenium, JUnit, TestNG, and Cypress used for automation. Different testing types, such as unit testing, integration testing, system testing, and user acceptance testing, help validate various aspects of the software. Performance testing ensures applications run efficiently under different loads, while security testing identifies vulnerabilities. Testing plays a vital role in delivering error-free, high-quality software, improving user experience, and reducing post-deployment issues.
