changes carried out at any level. The unit testing will
ensure that the unit is working as expected. The unit and
module testing will ensure that the unit and the module work
as expected. Unit testing and module testing will ensure
that the report or the unit and the module or the subsystem
are working as expected, but will not ensure that there has
not been an impact on the complete system. Regression
testing is required for any changes carried out at any level.
