Question

有以下Angular代码：

  $scope.clickByPoint = function(marker, eventName, point) {
    var geocoder, location;
    $scope.options.info.point = point;
    $scope.options.info.show = true;
    $scope.searched = false;
    $scope.address = "";
    geocoder = new google.maps.Geocoder();
    location = {
      lat: parseFloat(point.latitude),
      lng: parseFloat(point.longitude)
    };
    geocoder.geocode({location: location}, function(results, status) {
      $scope.searched = true;
      if (status === google.maps.GeocoderStatus.OK) {
        $scope.address = results[0].formatted_address;
      }
      $scope.$digest();
    });
  };

我的茉莉花测试：

  describe('$scope.clickByPoint', function() {
    var point;

    beforeEach(inject(function(_Point_) {
      point = _Point_.build('PointName', { latitude: 0, longitude: 0 });
    }));

    describe('try to find the address', function() {
      it('initialize google maps info window', function() {
        $scope.clickByPoint(null, null, point)
        expect($scope.searched).toEqual(true);
      });  
    })
  });

正如您所看到的，我正在尝试测试'scope.searched'变量已更改，但它始终为'false'，因为函数是异步的。如何正确测试此代码？提前谢谢。

在这种情况下，使用jasmine在测试中使用google.maps.Geocoder（）的模拟，因为，您正在测试clickByPoint（）逻辑而不是Google maps api。

    var geocoder = new google.maps.Geocoder(); 
    jasmine.createSpy("geocode() geocoder").andCallFake(function(location, callback) {
        // no wait time ...
        var results = {fake:'', data:''};
        var status = google.maps.GeocoderStatus.OK; // get OK value and set it OR redefine it with a Spy.
        callback(result, status);
     });

现在您可以使用您的测试：

    describe('try to find the address', function() {
        it('initialize google maps info window', function() {
            $scope.clickByPoint(null, null, point);
            expect($scope.searched).toEqual(true);
        });  
    })

使用Jasmine / Angular
