figures all the dependencies, and can plug into other APIs like Spring. See the docs and

6.5. Summary
This chapter covered a lot of ground in the testing arena. Groovy brings a simple
assert
statement into play that can be used for scripts and includes the
GroovyTestCase
class
that extends JUnit's capabilities. When it comes to managing dependencies, you can build
a stub implementation of an interface using closures, and you can build a more complete
stub using the
Expando
class.
Groovy also has the
StubFor
and
MockFor
classes, which can be used to test interac-
tions. They can even create mock objects for classes that are instantiated as local variables,
which is pretty amazing.
Finally, if you're willing to add an additional library, the Spock testing framework provides
a simple yet versatile API that still runs on your existing JUnit-based infrastructure. It also
has its own mock abilities and integrates with other libraries, like Spring and Tapestry.
Adding Groovy also adds a wide variety of options for testing Java and mixed Java/Groovy
projects. Hopefully the techniques in this chapter will help you decide where you can get
the most benefit from them.
