Software Testing
Software testing is a critical process in the software development lifecycle aimed at ensuring the quality, functionality, and reliability of an application. It involves systematically identifying and fixing defects to meet user requirements and deliver a robust product. The primary goal of testing is to detect issues early, minimize risks, and ensure the software performs as intended under various conditions.
There are two main types of software testing: manual and automated. Manual testing involves human effort to execute test cases, while automated testing uses tools like Selenium, JUnit, or TestNG to run tests efficiently. Testing is further categorized into functional testing, which verifies specific functionalities, and non-functional testing, which assesses performance, scalability, and security.

Common testing methods include unit testing, integration testing, system testing, and acceptance testing. Unit testing checks individual components, while integration testing ensures modules work together. System testing evaluates the entire system, and acceptance testing validates the software against user requirements.
Effective testing enhances software quality, reduces development costs, and builds user confidence. It is an iterative process requiring collaboration among developers, testers, and stakeholders. In today’s agile and DevOps environments, continuous testing plays a pivotal role in delivering high-quality software faster.
