Bug 25014 JUnit TestCase Wizard accepts empty string as test case name[junit]
Version: 2.0 Build id: 200210161553 The JUnit TestCase wizard accepts empty string as the test case name when there is no Java class currently selected. Steps for reproducing the error: 1 - Ensure there is no class currently selected in the Package Explorer (e.g. select a package or project); 2 - Activate New JUnit TestCase wizard; 3 - There will be no test case name selected. The "Finish" button will be disabled. Then erase the "Superclass" field content. The "Finish" button will be enabled. This opens a dialog with a message "Creation of element failed. Reason: Invalid name specified: .java" and a new entry is added to the error log. The stack trace will be attached.
