This paper presents the exploratory testing, an approach that has become very relevant in software testing, mainly due to the emerging the use of agile practices in the software development process to satisfy the needs of the market (Time to Market). However, it was possible to notice that it is a subject little discussed in the academic context. For this reason, this work uses gamification as a systematic strategy in teaching and learning of exploratory testing using case studies with two classes, which aims to maintain strong student involvement and an incentive for good performance, obtaining as results students prepared to use this testing approach. As a final result, the students achieved a good overall performance; with reports that gamification facilitated and collaborated greatly to achieve the best performance, converging with the quantitative data obtained. This can be evidenced by the fact that two case studies (classes) reached a percentage superior to 70% of conquest, that is, there was an excellent general performance analyzed by the proportion of medals obtained for the participation.
