1. what are the parts of a fuzzer? (Can choose more than one
option). test case generator, an oracle, a way to save the state at
the time of crash, software under test.
2. in system testing we think more along the lines of user
stories: true or false?
3. integration testing is a form of unit testing? true or
false?
4. if we want to override the behavior of an imported item we
need to use a patch: true or false?
5. a good code review treats the role like they are a:
supervisor, leader, friend or mentor?
