Look at the Python repo, but the idea is to put the approved text inline with the test.
In LabVIEW this would look like an approved bookmark.
The idea is to increase readability. You don't have to open a separate text file to see the desired results.
It is an interesting idea.
Would play havoc with difftools.
Also would play havoc with binary files and LUnit Parameterized Tests as well.
So maybe not?
