Answer: B
A common system maintenance problem is that errors are often
corrected quickly (especially when deadlines are tight),
units are tested by the programmer, and then transferred to
the acceptance test area. This often results in system
problems that should have been detected during integration
or system testing. Integration testing aims at ensuring that
the major components of the system interface correctly.
