Workshop: "Test Driven Development"
Time:
Thursday 09:00 - 17:00
Location:
Musikhuset Nr. 222
Abstract:
This tutorial demonstrates the development of a small example
application using test-driven development and related technologies. The
system will comprise a handful of Java classes that exemplify typical
components found in enterprise applications, including domain objects
and a service layer. The tutorial is structured into three ‘iterations’
which cover
- state-based testing with JUnit
- interaction-based testing with JUnit and jMock
- deployment in lightweight containers such as PicoContainer and Spring.
The iterations not only introduce the concepts but also provide room
for the discussion of trade-offs and edge cases, e.g. how to deal with
testing private methods and when not to use dynamic mocks but fake
objects. The implementation will make use of the Dependency Injection
pattern and the last iteration examines how this is supported by
lightweight containers.
Attendees gain an understanding of how proper use of test-driven
development fosters good design; through decoupling and interface
discovery for example. Attendees will also gather a nice catalogue of
the most commonly used patterns used in conjunction with test-driven
development.
