Potential Drawbacks

Limited coverage of Mockito within the course is a drawback, with users desiring more depth and examples given its importance in Java testing.
Lack of slides and visual aids makes certain sections reliant on verbal explanations, which could be improved by supplementing with diagrams or text-based illustrations.
Monotone delivery at times can affect engagement level, requiring learners to actively pay attention.
Files organized in the course seem messy and unclear; cleaner file organization would improve overall user experience.
