About jMock
jMock is a library that supports test-driven development1 of Java2 code with mock objects3.
Mock objects help you design and test the interactions between the objects in your programs.
The jMock library:
- makes it quick and easy to define mock objects, so you don't break the rhythm of programming.
- lets you precisely specify the interactions between your objects, reducing the brittleness of your tests.
- works well with the autocompletion and refactoring features of your IDE
- plugs into your favourite test framework
- is easy to extend.
