Software testing is essential to ensure the quality and reliability of software applications, enabling developers to authenticate software and assure stakeholders that the product meets technical and business needs. It involves running and analyzing an application to identify bugs and loops in the program, with various procedures to follow for successful testing. A test approach can be proactive or reactive, depending on when it is conducted - early stages of development or after the software has been built. The test environment should be understood to decide on a strategy that works best, and planning and executing test activities are crucial steps in the process. Automated testing tools can be used to identify areas for automation, providing benefits such as continuous delivery, high-quality software, and cost savings. Analyzing code quality is vital during testing, ensuring it meets its purpose and maintenance requirements, while bug reports should be maintained to retrieve and restore information. Critical inspection of test results helps formulate test procedures and release notes, allowing businesses to decide whether or not to validate the software for mass usage.
