- service in module ng
Any uncaught exception in angular expressions is delegated to this service. The default implementation simply delegates to $log.error
which logs it into the browser console.
In unit tests, if angular-mocks.js
is loaded, this service is overridden by mock $exceptionHandler which aids in testing.
Example:
angular.module('exceptionOverride', []).factory('$exceptionHandler', function() { return function(exception, cause) { exception.message += ' (caused by "' + cause + '")'; throw exception; }; });
This example will override the normal action of $exceptionHandler
, to make angular exceptions fail hard when they happen, instead of just logging to the console.
