Thank you, my only doubt is the fact that the first content fragment has the path to all the CF that need  to be imported. So, during the execution of the method if certain conditions occur, the linked CF is loaded. How do I make sure that during this step the test loads the right resource?

I created this model that uses multiple content fragment , the first content fragment has the link to the other that need to be loaded (if it needs to) , so how I can create a junit test in this case? 

I will like to have the possiblity to have my component to replace the tag whit a text For example: "this is a [tag] text"  (tag=normal ) in "this is a normal text " , i can replace the string and take the data from a content fragment but i'm not able to modify the text in a component
