运行 angular 使用 karma 和 jasmine 进行测试：minErr 错误

Question

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

Firefox 35.0.0 (Linux) MessageCtrl should get the correct message FAILED
    minErr/<@/home/jenselme/tests/javascript/angular/unit_tests/angular.js:78:12

    [2]</Karma/this.loaded@http://localhost:9877/karma.js:185:7
    @http://localhost:9877/context.html:47:5

这是我的 MessageCtrl.js:

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

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

还有我的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');
    })
});

我不知道那可能来自哪里。谁能帮帮我？

编辑 1：更正 MessageCtrl.spec.js

的代码

Answer 1

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