.) Create a Maven/Maven Quickstart project (or any other project)
.) Remove src/test folder in Files view
(.) Run Build to refresh the view, so Test Packages disappears, see ISSUE# 96264)
.) Create a java class
.) Click on java class/Tools/create Junit Test
-> Error shown, that no test folder could be found.

Better repsonse would be:
A dialoge should open, showing the error and asking if the test folder should be
created in order to creat test.

Reason:
A programming beginner might not be aware of the special notation, where and how
test folders should be created.
e.g. Netbeans expects a test folder to be configured in the project properties
for J2SE/Web... projects, but where are they to be configured in maven? And how
do they look like. And even in possible future java projects that might change
too. Therefore a dialogue could reduce the expected knowledge and increase
usability.
