In this article, Mark Levison addresses the difficulties encountered by developers willing to adopt TDD, the reasons why many start using TDD but give up after a short period of time, and what could be done to help developers make TDD a habit.

By doing a survey among developers, Mark noticed that:

  • People find it hard to TDD on their own, when they don't have much experience with it.
  • TDD Education so far has focused too much on problems that are simpler than the real world.
  • More time is needed to experiment and try without the usual pressure of releasing software at a specific date.
  • Languages used in the real world, like Visual Basic and JavaScript, are never used as examples in unit test documentation or classroom exercises.
  • The average code base is full of legacy code and no training was provided in how to improve this code.
  • There is never enough time to learn – there is always (artificial) pressure to ship product soon, and so we can't take the time to improve.

After discussing the reasons behind his survey findings, Mark proposes several solutions:

  • Classroom Training
  • Online Training
  • Patience
  • Measure
  • Instill Pride
  • Management
  • Pair Programming
  • Community
  • Coding Dojo
  • Reading Workshops
  • Periodic visits from a Coach

In order to make TDD a habit, Mark’s conclusion is that the developers need patience, practice, support from their management, a multipronged approach and their colleagues’ help.
