Test Driven Development (TDD) Demystified


As agile methodologies came to the power, testing and writing the code is bound as tight as never before. In that situation TDD concept shows itself in its best. But it need not be so obvious that the TDD is not only about writing huge number of tests. It is about understanding benefits and costs of the unit testing and early testing in general. This tutorial should give you some clues if the TDD is worth doing. We will discuss it without any prejudices and marketing phrases. The hardest part of starting with the TDD is to find a good starting point. It is quite common that people want to start but the first objections discourage them and they refuse TDD at all.
Within the course we are going to form groups of two or three and start to build up a simple project using TDD from scratch. We will focus on the advantages of this approach, but we will not close our eyes before all possible pitfalls. You might find there answers to some questions that caused your previous denial of TDD.

  • Part 1
    • TDD roots
    • Basic ideas of TDD
    • Unit testing
    • Unit testing tools
    • JUnit and its usage
    • Unit testing in TDD context
  • Part 2
    • Dependency injection
    • Objects double
    • Stub and Fake objects
    • Mocking objects
    • Mockito tool
  • Part 3
    • Code refactoring
    • TDD and unexpected expectation

The main goal of this workshop is to introduce participants with main concepts of TDD. In hands on exercises, the participants could try to develop some simple projects using TDD. The workshop doesn’t blindly adore TDD but tries to create balanced overview of the topic.
