Separation of JUnit classes into special test package?

I am learning the concepts of Test-Driven Development through reading the Craftsman articles (click Craftsman under By Topic) recommended in an answer to m

Answer 1

I use Maven. The structure that Maven promotes is:-

src/main/java/org/myname/project/MyClass.java

src/test/java/org/myname/project/TestMyClass.java

i.e. a test class with Test prepended to the name of the class under test is in a parallel directory structure to the main test.

One advantage of having the test classes in the same package (not necessarily directory though) is you can leverage package-scope methods to inspect or inject mock test objects.
