jMock is a library for testing Java code using mock objects. Mock objects help you design and test the interactions between the objects in your programs.

The jMock package:

  • makes it quick and easy to define mock objects, so you don't break the rhythm of programming.
  • lets you define flexible constraints over object interactions, reducing the brittleness of your tests.
  • is easy to extend.
