Compare Expected Vs Actual filenames in a directory

Scenario

A job may run, and the output of that job is a group of files dropped into a system directory. A test to determine that the job run correctly would be to test for the existence (and possibly other characteristics) of files in a directory.

Create a file collector to collect file details only into a stream and compare them against a stream with a pre-packaged filenames.

Solution:

• Create a file collector to collect only file details
• Create a stream of the results
• Merge / Compare the data from this stream with data from another stream.
