Good approach.

Good point, my proposal did not address "undisclosed". I'm not sure how 
much precedence this value should have in the logic.

This means that "automatic" + "manual" = "manual" ...bug or feature? ;)

I think this nesting of IF...ELSE is rather confusing, I hope we can 
reduce the rules to a small set that is easy to overview. Here is 
another attempt of the rules:

#1. if all sub-tests were carried out in the same test mode, then the 
test mode of the combined test is same.

#2. if the test mode of any of the sub-tests is "undisclosed", then the 
test mode of the combined test is also "undisclosed".

#3. for all other test mode combinations of sub-tests, the test mode of 
the combined test is "semi-automatic".


Does this cover all the combinations? Is the outcome what we want 
(especially the strong effect of "undisclosed" and "semi-automatic")?


Regards,
   Shadi
