Loading N custom modules with a nested use() call.js

// This assumes the file names are directly mappable to the module names declared
// in the YUI.add() calls inside those files.
YUI({
    modules: {
        'myapp.tests.core': { fullpath: '/path/to/core.js' }
    }
}).use('myapp.tests.core', function (Y) {
    var tests = [ '0001','0002', ... ],
        i, len;

    for (i = 0, len = tests.length; i < len; ++i) {
        Y.config.modules[tests[i]] = { fullpath: '/standard/path/'+tests[i]+'.js' };
    }

    tests.push(function (Y) { // this will become the use callback
        /* all tests are available here */
    });

    Y.use.apply(Y, tests); // loads all test modules and executes the callback above
});
