Software testing is key to software quality assurance development. During complete software development, life cycle bugs, and errors can be added in phases. Every time software testing is a very tough and costly process to confirm the quality of the developed product. In manual testing, the tester makes particular test cases manually that are performed in a way to find the error/bugs. In automated testing technique, it is a very fast process as it is mostly done with machines with fewer humans involved in this software testing technique. This review paper aims to define the set of different emerging tools and methodologies. A software testing technique to test the software development process. The aim of this paper is to explore the “software development lifecycle” (SDLC) and its advantages. It is software testing is an advanced version through the help of safekeeping features, testing tools, security models, and most important test cases used in testing. Software security testing was measured as a practical responsibility by application creators. The future of software testing technique is to continue the feature of software testing it must check the safety of the application with the right technique. The final purposes of safety testing are to confirm the strength and to stop safety weaknesses to open the application.
