By default the test cases will be automatically created to test category "Import". By setting this value the root category where the test cases will be created to can be configured.
For example, if the mapping identifier constructed for the test is "com.mycompany.SomeTest", and this setting is set as "Some/Category/Path", a test case named "SomeTest" will be created to
Some/Category/Path/com/mycompany
.. category.
