C: Developers are not objective about their own code
Giải thích
C is correct. This is the biggest problem because developers have biases toward the accuracy and implementation of their own code. Testers and developers think differently and testers can be more objective as they are not invested in the code. A and B are not necessarily true – some developers are good testers and have a good quality focus. D is not correct because unit testing is part of their job and time should be made in the schedule for at least unit testing. lifecycles
