Due the constant evolution of software development and its growing complexity, more is being required from professionals to master different phases of the software development process, which includes the testing phase. This has an impact on the training of new professionals, since the undergraduate curricula is supposed to address this complexity. In this sense, software testing has its place in undergraduate CS-related courses, still the literature points out that the needed attention and importance is not given by the students and even by academic curricula. One of the possible causes that can be mentioned is the way of offering this content, which is usually part of a Software Engineering introductory course, perceived by students as something tedious and not important for their career. Thinking about this scenario, this paper describes the design and implementation of Testable.
