Question

我正在尝试为角度控制器编写基本测试。我使用Jasmine框架和业力作为测试运行员。我的测试失败，出现以下错误：

Firefox 35.0.0 (Linux) MessageCtrl should get the correct message FAILED

这是我的MessageCtrl.js：

var app = angular.module("lastLine", []);

app.controller('MessageCtrl', ['$scope', function($scope) {
    $scope.getMessage = function(name) {
    return 'Hello ' + name;
    };
}]);

我的MessageCtrl.spec.js：

describe('MessageCtrl', function() {
    var $scope;

    beforeEach(module('MessageCtrl'));

    beforeEach(inject(function($rootScope, $controller) {
        $scope = $rootScope.$new();
        $controller('MessageCtrl', {
            $scope: $scope
        });
    }));

    it('should get the correct message', function() {
        var message = $scope.getMessage('Cedric');
        expect(message).toBe('Hello Cedric');
    })
});

我不知道可能来自哪里。任何人都可以帮助我吗？

编辑1：更正MessageCtrl.spec.js的代码

知道了。 MessageCtrl.spec.js中的代码是错误的。第beforeEach(module('MessageCtrl'));行应为beforeEach(module('lastLine'));
