The process of executing an application with the goal of identifying software bugs (errors or other problems) is known as software testing. The demand for software applications has raised the bar for established software quality assurance. This phase of the software development life cycle is regarded as the most crucial. Testing can evaluate the software item's features and determine any discrepancies between the real and recommended circumstances. Software testing reduces software expenses and minimises errors. We go over numerous software testing methods and approaches in order to achieve this. The objective of this research is to examine several software testing methodologies that have been enhanced to enhance quality assurance.
