Software testing plays a crucial role in delivering reliable software. Currently, research is ongoing on how software developers and testers acquire this knowledge of software testing to deliver reliable software and what kind of knowledge is being transferred to developers and testers. In an effort to gain more insight into this area, we will focus on answering which software testing topics are being discussed in dedicated software testing courses and software engineering courses in top-ranked universities. Our findings show us that White-box testing, Black-box testing and the discussion of test levels are the most commonly discussed topics in universities.
