Software Testing is a crucial phase in the software development life cycle (SDLC) that involves evaluating a software application to identify defects, errors, or issues before it is released to end-users. The primary goal of software testing is to ensure that the software functions correctly, meets the specified requirements, and performs reliably in various scenarios. Testing encompasses a range of activities, methodologies, and tools to validate and verify software quality.

Applications:

• Functional Testing: Functional testing ensures that the software’s features and functions work as intended. It includes unit testing, integration testing, system testing, and acceptance testing.
• Performance Testing: Performance testing assesses the software’s speed, scalability, and responsiveness under different conditions, such as load testing, stress testing, and scalability testing.
• Security Testing: Security testing identifies vulnerabilities and weaknesses in the software, including penetration testing, vulnerability scanning, and code review.
• Usability Testing: Usability testing evaluates the software’s user-friendliness, interface design, and overall user experience.
• Regression Testing: Regression testing verifies that recent code changes or updates have not introduced new defects or impacted existing functionality.
• Compatibility Testing: Compatibility testing ensures that the software works correctly on different devices, browsers, and operating systems.
• Automated Testing: Automated testing uses test scripts and tools to execute test cases, speeding up the testing process and improving test coverage.
• Mobile App Testing: Mobile app testing focuses on assessing the functionality, performance, and compatibility of mobile applications on various devices and platforms.
