For those tests that check signature generation of two builds, it would be useful (for debugging purposes) to show more info on the stamps difference. One approach would be to generalized what is proposed on the series [1] [1] http://lists.openembedded.org/pipermail/openembedded-core/2017-August/140553.html
Bulk move from 4.99 or 0.00 to 5.99
Tests now give a lot more info.
