co(function*(){
    //fs
    var r = yield fs.$exists(__dirname);
    r.should.should.be.ok
    var data = yield fs.$readFile(__filename ,"utf8");
    data.indexOf('$readFile').should.not.equal(-1);
    //child process
    var r = yield child_process.$exec("node -v")
    r[0].should.be.ok      	//stdout node version
    r[1].should.not.be.ok; 	//stderr should be ''
    r[2].should.be.ok   	// child_process.exec returned child ChildProcess
    //dns
    var r = yield dns.$resolve4("github.com");
    //zlib
    var b = yield zlib.$gzip(new Buffer("github.com"));
