All Code is Agile Code

Refactoring Test Code
Includes a list of code smells specifically for test code and this reason as to why test code is important: "The downside of having many tests, however, is that changes in functionality will typically involve changes in the test code as well. The more test code we get, the more important it becomes that this test code is as easily modifiable as the production code."

"The most common case for test code will be duplication of code in the same test class. This can be removed using Extract Method (F:110). For duplication across test classes, it may provide helpful to mirror the class hierarchy of the production code into the test class hierarchy. A word of caution however: moving duplicated code from two separate classes to a common class can introduce (unwanted) dependencies between tests."
