We have built the happy path of our application. But in the real world an error can occur during communication with the server. To manage this there are two ways:
The
failmethod of the AJAX promise:ProductResource.remove() .done(function(){...}) .fail(function(response){ console.error(response); alert("Error in the communication. Check the console!"); });A global AJAX error handler:
$(document).ajaxError(function(event,response) { console.error(response); alert("Error in the communication. Check the console!"); });
If you have a consistent error format, the global handler is a very good choice to handle errors.
To test an error, update the status attribute of one mock from 200 to 404 or 501:
$.mockjax({
url: /^\/products\/([\d]+)$/,
type:"DELETE",
dataType: "json",
responseTime: 750,
status:404,
responseText: {
"data": {
text: "Product deleted"
}
}
});
