Software testing is a critical phase in the software development lifecycle that involves evaluating a software application or system to ensure it meets specified requirements and functions correctly. Testing helps identify defects, bugs, or inconsistencies in the software, allowing developers to address them before the product is released to users.
There are various types of software testing, including functional testing, which verifies that the software performs its intended functions correctly; usability testing, which assesses the user experience and interface design; performance testing, which evaluates how the software performs under different conditions such as load or stress; and security testing, which checks for vulnerabilities and weaknesses in the software's security measures.
