did you know about tests automation?

And a plugin that sends command in javascript for browser . Here's an example :
1 ) open the url http://mysite.com
2 ) send a javascript command:
$ ( "input # login" ) val ( " admin .");
3 ) send a javascript command:
$ ( "input # pass" ) val ( " 123 " ) . ;
4 ) send a javascript command:
$ ( " # button btnlogin " ) click ( .);

Note : The intent is to see these commands running in browser
