i have been trying to create a test case for my custom module but i am confused in handler scenario. they have user curl handler but the problem is data passed in that curl file in array form and i am not able to get where from this data is coming from, is it from fixture (i.e fixture field name) or from repository also there are some entities in array which are not present in these xml files, then where are they coming from ????
Just want to confirm item name in repository also ,these can be anyname or is predefined as dev docs these are the blocks holding widget instances
