+# Dependency Breaking Katas
+
+Exercises to practice breaking dependencies in legacy
+code to create tests for it.
+
+## Goal
+
+We have some legacy code. We need to make changes.
+To make changes we need to introduce tests first.
+We might have to change some code to enable testing.
+We need to introduce so-called Seams (see [Michael
+Feathers' Working Effectively with Legacy
+Code](https://www.goodreads.com/book/show/44919.Working_Effectively_with_Legacy_Code)).
+
+Changing code without test is risky, so we want to
+
+* Only change as little code as possible.
+* Rely on automated Refactoring tools as much as possible.
+* You must not change the public API of the class.
+
+### Assignments for Techniques
+
+* Parametrise Constructor
+* Subclass And Override Method
+* Extract And Override Call
+* Replace Global Reference With Getter
+* Extract And Override Factory Method
+
+Planned
+
+* Extract Interface
+* Adapt Parameter
+
+### Task
+
+Each task presents you with a class and some collaborators.
+
+* Bring this class under test. Make sure to cover all paths in the core logic.
+* There is an existing test class with a first test case which might or might not work.
+* You cannot change collaborators because they are used by other teams as well.
