Yes you can do similar kind of tests with Yatsy.
However, EUnit is much more light-weight. We are using:

Yatsy - for system tests.
It can execute on the target node or from a remote node.
We test major parts of our system where we prepare DB contents,
setup timeouts and config data. We run tests both within the
target node as well as remotely via our Xml-Rpc interface.

EUnit - for unit tests (i.e in general development where appropriate).
While you are developing code you define input and expected output
for local code in the module and run the EUnit generated test/0
function until your assertions are fulfilled.
