Thank you @mrc  
I am almost in the final stage of the workflow, so I’ll try to finish it and hopefully, I will be able to share the code and everything to build a test case for loops. 🙂

How may I implement the [default value](https://cwl.discourse.group/t/constructing-a-default-value-for-a-tool-input/161/4) from this example for File? I am trying to access the file from it’s location and read it inside the tool?
