Software quality is a key concept in software engineering, since it determines the degree in which a software system meets its requirements and user expectations. Verification and Validation is the name given to set of activities aimed to assess a software system. The goal of V&V is to ensure the quality of a piece of software while reducing the number of defects. The two core activities in V&V are software testing (evaluation of a running piece of software) and static analysis (assessment of software artefacts without its execution).
Automated software testing has experienced biggest advances in the last few decades. In this arena, the JUnit framework has a remarkable position. JUnit was designed to be a unit framework for the JVM. Nowadays, it is a fact that JUnit is the most popular test frameworks in the Java community, providing a comprehensive programming model to create and execute test cases. In the next section, we will discover the features and capabilities provided by the new version of the framework, JUnit 5.
