Matthias Noback:
Testing actual behavior
Jun 26, 2018 @ 13:48:02

Matthias Noback has posted another article covering domain-driven development practices, this time focusing on testing actual behavior and some of the downsides that can come with it and domain-driven development.

He breaks the article up into three main sections:

  • The downsides of starting with the domain model
  • The downsides of starting with the smallest bricks
  • The downsides of your test suite as the major client of your production code

Each includes a description of the downsides related to the topic and, where it helps, code to illustrate the issue. The post also includes three experiments to try to help prevent some of these downfalls from happening (including not testing constructors and not adding getters).

Tests are not the main use case of an object, they should guide the development process and make sure you write exactly the code that you need. This means not sacrificing the object's encapsulation just to make it testable.
