grunt.registerTask(process.env.X, 'Running all tests based on the organism', function() {
        var tests = grunt.file.readJSON('test/tests.json');
        var category = tests[process.env.X]

        for (var i in category) {
            var component = category[i].path + "\n";
            grunt.config.set('simplemocha.sauce.src', 'test/sauce/' + component);
            grunt.task.run('testing');
        }
});
//process.env.X was the individual component selected. Then it went through each category associated with the component to grab the path.
