%%% @doc Plugin handling test
%%%
%%% This test checks if plugins are loaded correctly.
%%%
%%% It has three applications:
%%% <ol>
%%%   <li>fish. top-level app, has one dependency: `dependsonplugin'.
%%%       It also loads a plugin from CWD which creates
%%%       base_dir_cwd_pre.compile on pre_compile.</li>
%%%   <li>dependsonplugin, has one dependency: `testplugin' and loads
%%%       the testplugin_mod plugin.</li>
%%%   <li>testplugin. This is a plugin application which creates
%%%       plugin_pre.compile on pre_compile. It also loads a plugin from CWD
%%%       which creates dep_cwd_pre.compile on pre_compile.</li>
%%% </ol>
