angularjs的依赖注入

[qq_29576895]

我想向config中注入自定义provider，请问怎么注入
myApp.provider('test',function(){
this.$get = function(){
return {
test:alert("23")
};
}
});
myApp.config(['$routeProvider','$httpProvider',function($routeProvider,$httpProvider,testProvider) {
$routeProvider.otherwise({
redirectTo: '/home'
});
testProvider.test;
routeProvider = $routeProvider;
$httpProvider.interceptors.push('httpInterceptor');
}]);
提示错误
