I'm not sure these are real benefit but:

- it does not use OUnit (at least since version 0.4). You can define your own 
"test" combinators[1].
- it produces a binary which produces tests, which have a nice man page, a nice 
output with lots of colors
- you can easily play only a subset of the tests, and display one specific test 
output

Some examples: irmin-chunk[2] or ciso[3].
