firm about insisting that a bug is not a “feature” if it should be fixed
diplomatic, sensitive to the way they may react to criticism
All of the above

26) In which order should tests be run?

the most important tests first
the most difficult tests first(to allow maximum time for fixing)
the easiest tests first(to give initial confidence)
the order they are thought of

27) The later in the development life cycle a fault is discovered, the more expensive it is to fix. Why?

the documentation is poor, so it takes longer to find out what the software is doing
wages are rising
the fault has been built into more documentation, code, tests, etc

when time for testing has run out.
when all planned tests have been run
when the test completion criteria have been met
when no faults have been found by the tests run

31) Coverage measurement

is nothing to do with testing
is a partial measure of test thoroughness
branch coverage should be mandatory for all software
can only be applied at unit or module testing, not at system testing
