etest - simple distributed testing

The purpose of this app is to make it easy to run a controlled parallel test from many erlang nodes concurrently with one simple central console.

In the most simple cases, you can login to remote machines, start up erlang distributed nodes (e.g. erl -sname testing -noshell -detached) and then use them as slaves for running tests.

etest delivers the latest code to all your slaves nodes and tells them to start running.

Example (using included modules):

etest_dist:start_slaves([etest_sample, etest_node_sup],
                        etest_node_sup, start_children,
                        [etest_sample, start, [2], 5]).

This will use net_adm:world() to visit .hosts.erlang if possible and will then deploy and run 5 instances of etest_sample:start/1 with an argument of 2 on every node it finds.
