Pros and Cons of Auto. Test Gen. at System-level Pros: No false alarms Cons: Low bug detection power due to large search space Execution tree Nowadays, automated test generation techniques are widely used in academia and industry at system-level and unit-level. First, let’s look at the pros and cons of system-level test generation. The pros of system-level test generation is that we do not need to worry about false alarm. We can give any inputs to a target program and the program should handle unexpected inputs. On the other hand, the cons of system-level test generation is low bug detection power due to large search space. Within a given limited time, it can explore only a few part of search space, so it can miss corner case bugs. Explored paths of a program Real bug
