Testing strategy for multiple platforms

for each platform. Depending on the nature of the software components on each
platform, the appropriate testing strategy questions can be asked and answered just
for that platform. This allows clarity and independence of testing priorities across the
platforms involved, yielding more thorough test planning for the entire development
effort.

4.5 PUTTING THE TESTING STRATEGY
INTO PERSPECTIVE

The rich repertoire of testing techniques can be grouped into four major ap-
proaches to simplify the understanding of when the approaches are appropri-
ate during the software development life cycle. If these four major approaches
are placed on a grid with the development phases and the different layers of
software required to operate the application under test, useful patterns arise
for test planning purposes. These patterns are further useful in determining
what needs to be tested and what does not need to be tested at a fairly high
level.
