How to mock an AJAX call?

1

Hi,

we are trying to develop tests for our modules and would like to mock an Ajax call. We have tried to do something like this:

Code:
AjaxMock = {
init : function (responseText) {
this.reset();
Ext.Ajax.on(‘beforerequest’, function (conn, options){
conn.responseText = responseText || ‘’;
options.success.apply(null, arguments);
conn.abort(conn.transId);
return false;
});
},

reset : function () {
    Ext.Ajax.purgeListeners();
}

};
But this did not work as intended. Any help would be appreciated on how to mock the response text and stop the outbound connection.
