Question 22

Question
A test plan included the following clauses among the exit criteria: # System test shall continue until all significant product risks have been covered to the extent specified in the product risk analysis document. # System test shall continue until no must-fix defects remain against any significant product risks specified in the product risk analysis document. During test execution, the test team detects 430 must-fix defects prior to release and all must-fix defects are resolved. After release, the customers find 212 new defects, none of which were detected during testing.

Question 31

Question
As a test leader you are collecting measures about defects. You recognize that after the first test cycle � covering all requirements - subsystem C has a defect density that is 150% higher than the average.
