Grails' controller methods are not shown as entered

Hello,
For some reason the method in a controller is marked as not entered even though the content inside is shown to be executed. Please can you help me rationalize/ understand this?

Please refer to me screenshots:
index_method_not_executed.png: to see that the index() method is not executed even though its contents are.
test_for_index_method.png: the test that is run to get the method to run.
