The Overview of Software Testing: Types, Methods, and Levels

Abstract

Software development life cycle (SDLC) is a software development model consisting of different phases i.e., analysis, design, coding, testing, deployment, and maintenance. The analysis phase is the primary phase in which all the requirements aregathered and analysed which is further used for designing and coding. The next phase is testing.Software testing is a process of evaluating software so as to check whether it satisfies the requirements of the customer or not and also to find the errors, defects, bugs, etc. Software testing is used to improve the quality and accuracy of the software. Software testing can be done manually or automated. There are many reasons why software testing is important like for security, satisfaction of the customer, enhancing the development process, to check whether all modules and features of the software are running properly or not. Software testing does not deal only with the functional part like unit testing, integration testing, etc. but it is also used to check the non-functional aspects like performance, compatibility, usability, etc. This paper presents the different types of software testing i.e., functional and non-functional, methods, and levels of software testing.Comparison betweensoftware testing methods like Black Box, White Box, and Gray Box are also explained.
