In my project ("Java Project with Existing Ant
Script" type), I have a separate directories for
my application's source files and the unit test
source files (each with the same package
hierarchy, so that the tests can access package
scope fields & methods).  I have both these Source
Package Folders specified in the project properties.

If I create a new unit test using the File -> New
File -> JUnit -> Test for Existing Class, there is
a drop-down list for the Location which allows me
to generate the test directly in my test sources
folder.  However, when creating a unit test for a
class using the right-click Tools/JUnit/Create
Test action, it always puts the resulting file in
the same directory as the original class and I
have to use cut & paste in the Explorer window to
move it to the unit tests source tree.

It would be useful if the RMB Create Tests dialog
also contained a drop down list of the project's
Source Folders, so that I can select to have the
files generated directly in their desired location.

I would have added this as a comment to Issue
47448, but it says in there "For all other
comments ... please file separate issue reports",
so I'm doing as requested ;-)
