我有一个简单的控制器：

app.controller("RegisterController", function ($scope, $location) {

    // Do something

});

我要做的就是测试这个控制器的定义：

describe('RegisterController', function() {

    var $rootScope, $scope, $controller;

    beforeEach(module('myApp'));

    beforeEach(inject(function(_$rootScope_, _$controller_){
        $rootScope = _$rootScope_;
        $scope = $rootScope.$new();
        $controller = _$controller_;

        $controller('RegisterController', {'$rootScope' : $rootScope, '$scope': $scope});
    }));

    it('should exist', function() {
        expect($controller).toBeDefined();
    });
});

我收到以下错误：

TypeError: undefined is not a function

您正在尝试测试错误的东西，您不想测试 $controller ，它只是 ngMock 中的一个服务，用于测试您自己的控制器。 https://docs.angularjs.org/api/ngMock/service/ $controller

基本上你需要使用这个服务来创建控制器。我创建了一个 plunkr 示例。 http://plnkr.co/edit/DQZGZERfCptAlgeBUUqb?p=preview

现在，如果您将控制器的名称更改为 RegisterController1，测试将失败，希望这会有所帮助。`

var app = angular.module('myApp',[]);
app.controller("RegisterController", function ($rootScope, $scope) {

    // Do something

});

describe('RegisterController', function() {

    var $rootScope, $scope, $controller,registerController;

    beforeEach(module('myApp'));

    beforeEach(inject(function(_$rootScope_, _$controller_){
        $rootScope = _$rootScope_;
        $scope = $rootScope.$new();
        $controller = _$controller_;

        registerController = $controller('RegisterController', {'$rootScope' : $rootScope, '$scope': $scope});
    }));

    it('should exist', function() {
        expect(registerController).toBeDefined();
    });
});
