Running applications with different log levels, tracing output, comparing screenshots with different levels of fuzzy comparaion
- it's not faraway.
How would fuzzy comparison work?
See projects findimagedupes and gqview (duplicate window, hit 'D' in gqview interface), both presented as packages in standard Debian. These fuzzy compare images. You can find some images which can be used as input here:

Results vary, findimagedupes is quite good, however its accuracy is below 100%.
