我想我明白了代碼......但driverList甚至從哪裏來？ driversList甚至沒有定義在代碼中的任何地方...與業力和茉莉花角測試
這些測試也通過，所以我明顯不正確的思想driversList應該重新命名driversStandings什麼的。
describe('Controller: driversController', function() {
// First, we load the app's module
beforeEach(module('F1FeederApp'));
// Then we create some variables we're going to use
var driversController, scope;
beforeEach(inject(function ($controller, $rootScope, $httpBackend) {
// Here, we create a mock scope variable, to replace the actual $scope variable the controller would take as parameter
scope = $rootScope.$new();
// Then we create an $httpBackend instance. I'll talk about it below.
httpMock = $httpBackend;
// Here, we set the httpBackend standard reponse to the URL the controller is supposed to retrieve from the API
httpMock.expectJSONP("http://ergast.com/api/f1/2013/driverStandings.json?callback=JSON_CALLBACK").respond(
{"MRData": {"StandingsTable": {"StandingsLists" : [{"DriverStandings":[
{
"Driver": {
"givenName": 'Sebastian',
"familyName": 'Vettel'
},
"points": "397",
"nationality": "German",
"Constructors": [
{"name": "Red Bull"}
]
},
{
"Driver": {
"givenName": 'Fernando',
"familyName": 'Alonso'
},
"points": "242",
"nationality": "Spanish",
"Constructors": [
{"name": "Ferrari"}
]
},
{
"Driver": {
"givenName": 'Mark',
"familyName": 'Webber'
},
"points": "199",
"nationality": "Australian",
"Constructors": [
{"name": "Red Bull"}
]
}
]}]}}}
);
// Here, we actually initialize our controller, passing our new mock scope as parameter
driversController = $controller('driversController', {
$scope: scope
});
// Then we flush the httpBackend to resolve the fake http call
httpMock.flush();
}));
// Now, for the actual test, let's check if the driversList is actually retrieving the mock driver array
it('should return a list with three drivers', function() {
expect(scope.driversList.length).toBe(3);
});
// Let's also make a second test checking if the drivers attributes match against the expected values
it('should retrieve the family names of the drivers', function() {
expect(scope.driversList[0].Driver.familyName).toBe("Vettel");
expect(scope.driversList[1].Driver.familyName).toBe("Alonso");
expect(scope.driversList[2].Driver.familyName).toBe("Webber");
});
});
