The Riak Test Rebar Plugin
This rebar plugin introduces three commands to rebar the integration of riak_test.
The plugin is built to integrate with repos like riak and riak_ee. The following is an addition I made to riak_ee's rebar.config to setup the plugin
{plugins, [rebar_riak_test_plugin]}.
{riak_test, [
{test_paths, ["riak_test/tests", "../riak_test/tests"]},
{test_output, "riak_test/ebin"}
]}.
The first line just enables the plugin. Since riak_test is included as a dependency, this won't work unless you've already done a make deps and make compile, but if you haven't done that, then what are you testing?
test_paths are all the paths on which riak_tests exist. The plugin will compile every module it finds in these paths into the test_output folder. What you end up with is a folder containing nothing but the complete set of compiled test modules for testing.
All of the rt_* commands only operate on the parent project.
./rebar clean deletes the compiled modules from test_output.
➜ riak_ee git:(jnd-riak_test) ✗ ./rebar clean
==> cluster_info (clean)
...
==> riak_ee (clean)
Removing test_output dir riak_test/ebin
./rebar compile compiles all source modules in test_paths into the test_output directory.

./rebar rt_run config=rtdev test=verify_build_cluster runs the test specified by test with the configuration specified by config. It is a glorified pass-through for the riak_test escript, minus the glory.

Once this PR is merged, and we integrate this plugin into riak_ee, we'll be able to move EDS specific tests into the riak_ee repo in preparation to open source riak_test
