This master thesis gives an overview of Quality Assurance and Quality Control tools and techniques used in software testing. Quality Assurance (QA) and Quality Control (QC) are the two most important processes in the software development process. Both have the same purpose and are very important for quality software development, but they have different approaches, environments and tools. The duration of both processes and how they relate to each other are explained. In addition, it is important to know where to place the focus, when using the process-oriented techniques (QA) and product-oriented techniques (QC). We need to learn how to set important goals, minimize software bugs and learn how to detect them. This is needed in order to ensure quality control standards while testing software products. First, we must be able to explain the importance of roles and responsibilities in the development process regarding Quality Assurance. We need to establish the difference in responsibilities when various software teams are involved in the quality assurance process during the entire development life cycle (QA), or when only the testing team takes the responsibility in the entire development software testing life cycle (QC). In the main part of this thesis, the best practices are presented and some of the tools that can assist in both the Quality assurance and the Quality Control processes are analyzed. The tools were divided into categories such as: “Management and technical analyses tools”, “Inspection tools (code reviews)” and “Testing tools”. At the end of this thesis, the basics of quality management are laid out, and insights and key considerations regarding quality assurance and control are presented.
