Part 2
Different testing strategies
This part of the topic reveals the various strategies and techniques used in
testing. Here we take a more scientific and theoretical approach to explain the
differences. We describe incorporating mock objects, or stubs, and dive into
the details of in-container testing.
The first chapter of this part describes different techniques for improving the
quality of your tests—measuring test coverage, practicing test-driven develop-
ment, and writing testable code.
The sixth chapter of the topic is dedicated to stubs. We look into another
solution to isolate the environment and make our tests seamless.
The seventh chapter starts by explaining what mock objects are. We give a
thorough overview of how to construct and use mock objects. We also give a real-
world example showing not only where mock objects fit best but also how to ben-
efit by integrating them with
JU
nit tests.
The last chapter describes a totally different technique: executing tests
inside a container. This solution is different from the previous ones, and just
like them it has its pros and cons. We start by presenting an overview of what
in-container
means and how it's achieved, and at the end of the chapter we
compare the mocks/stubs approach to the in-container approach. Along with
the theoretical benefits, this chapter serves as a good starting point to under-
standing chapters 13 and 16.
