We should check the lower-level message too (i.e. the bit after the colon at the end): I've seen cases where this part of an error message hasn't been checked properly and the string is actually invalid for some reason. (We don't need to test every possible lower-level code path that could result in the specific failure, just one example).

You may also wish to show that the binary is not dumped (as opposed to garbage being dumped).
