Typically a test like this that makes assumptions on the layout or contents of the image will need some amount of conditionals based on the build configuration. There is a framework for this in place in case you need it. I'm thinking about various kinds of instrumented builds that may create additional files in the image.


I have at least some ideas to add more checks.  E.g. if an include  folder is present in the image , it should contain just headers.

If a legal folder is present, there is also only a rather limited number of files 'allowed' .

Regarding corner, cases - yes sure there can be some; maybe we need followup actions to handle them.
