experimental results. The objective of integration is to exercise aspects of an update that will interact
with other parts of the developmental baseline to ensure that in-context transformations are correctly
performed. The objective of regression prevention is to ensure that the addition of an update set does
not make any unintended changes in CONTAIN results.
Testing is carried out in three distinct stages. The developer is responsible for the fmt testing stage,
which focuses on determining that the update functions correctly and executes as intended. During
the second phase, one or more internal beta testers use the modified code and focus on determining
that there are no undetected errors in the update. The integration tester is responsible for the final
testing stage, which determines that the new release, with all updates in place, functions correctly.
Table D-1 summarizes the relationship between the developmentimaintenance functions and
indicates the type of errors they protect against.
D.2.6. 1 Developmental Testing. In developmental testing, the developer formulates test problems
and executes them to verify the update design. The developmental testing program is used to
uncover and correct problems with the update. The developmental tests are initially used to
determine that the update code is indeed executable. Once the executable code is created, the
developmental tests are used to verify that the update executes as the developer intended. Finally,
the developmental tests are used to verify that the code produces results that are accurate.
