Objectives
The objective of this chapter is to introduce software testing and
software testing processes. When you have read the chapter, you will:
■ understand the stages of testing from testing during development
to acceptance testing by system customers;
■ have been introduced to techniques that help you choose test
cases that are geared to discovering program defects;
■ understand test-first development, where you design tests before
writing code and run these tests automatically;
■ know about three distinct types of testing—component testing,
system testing, and release testing;
■ understand the distinctions between development testing and user
testing.
