+Expectations
+============
+
+Having a way to run after each commit a test on a list of samples and check if
+the output and the logs are the ones expected by.
+Easy way to check it on the rPi itself before releases.
+
+
+What to think about
+===================
+
+* Exhaustive list of files, edge cases
+* Check the logfiles
+
+Ideas
+=====
+
+Source keys:
+- Working documents, one / multiple partitions
+- Non working documents: one / multiple partitions
+- different FS on different partitions
+- Non working FS
+- Malicious documents (very slow, might break the conversions)
+
+Destinations keys
+- empty, big enough
+- empty, too small
+- broken
+- not empty
+- unmountable (wrong/broken fs)
+
+
+
+Things to try out
+=================
+
+
+Run the image in qemu, process USB keys from there
+
