我是茉莉和业力的新手。我相信我已经正确设置了环境,并且我能够运行非常基本的单元测试,但是一旦我尝试实例化控制器,我就会收到一个未知的提供程序错误,我不确定如何调试它。我是否需要传递stateProvider依赖项?我在角度种子示例中没有看到这一点。
Bower.json:
{
"name": "starter",
"description": "A starter project for AngularJS",
"version": "2.0.0",
"homepage": "https://starter.com",
"private": true,
"dependencies": {
"angular": "1.2.x",
"angular-route": "1.2.x",
"angular-loader": "1.2.x",
"angular-mocks": "~1.2.15"
}
}
家庭控制器:
angular.module('home').controller('Home', function($scope, $rootScope, $state) {
console.log($scope.pageType);
$rootScope.pageType = 'home';
/*
* Takes in a state and transitions the app to that state.
*/
$scope.goTo = function(value) {
$state.transitionTo(value);
}
/*
* Handles what happens after clicking log-in
*/
$scope.loginClicked = function() {
$state.transitionTo('log-in');
}
});
测试文件:
'use strict';
/* jasmine specs for controllers go here */
describe('Home', function() {
beforeEach(module('home'));
it('should run tests', inject(function() {
expect(null).toBeDefined();
}));
it('should not say true equals false', function() {
expect(false).not.toBe(true);
});
it('should say true equals true', function() {
expect(true).toBe(true);
});
it('should say false does not equal true', function() {
expect(false).not.toBe(true);
});
it('should create "phones" model with 3 phones', inject(function($controller,$rootScope) {
/*
*
* COMMENTING OUT THESE LINES = PASS
*
*/
var scope = $rootScope.$new(),
ctrl = $controller('Home', {$scope:scope});
expect(ctrl).not.toBe(null);
}));
});
错误:

如果未包含其中一个注射剂模块,您将收到此错误。
例如,你有
beforeEach(module('home'));
如果您的$state
依赖项不在home
模块中,则还需要包含该模块。我不熟悉$state
(我认为它是angular-ui的路由器?只有angular.js服务应该以{{1}}开头)。如果它是角度ui,那么你应该如何设置:
$
这样,angular的测试运行器就知道运行测试需要哪些模块。
实际上,只要您将beforeEach(module('ui.router'));
beforeEach(module('home'));
依赖项定义为该模块的依赖项,包含home
模块就应该为您执行此操作。如果配置正确,则可能需要查看包含在测试中的文件的顺序。例如,确保测试中包含ui-router文件,并在karma配置中的ui.router
模块之前引用它。

当您在控制器中包含$state
依赖项时 - 您需要在控制器单元测试中提供$state
。
var $scope = $rootScope.$new(),
ctrl = $controller('Home', {
$scope: $scope,
$state: {} //Or inject the state using the injector service and then you can use some jasmine spies to mock the function calls or just to spy on 'em.
});
expect(ctrl).not.toBe(null);
你的阻止变化......
it('should create "phones" model with 3 phones', inject(function($controller, $rootScope, $state) {
/*
*
* COMMENTING OUT THESE LINES = PASS
*
*/
var scope = $rootScope.$new(),
ctrl = $controller('Home', {$scope:scope, $state: $state});
expect(ctrl).not.toBe(null);
}));
然而,在我的单元测试设置中,我喜欢为控制器设置创建功能,正如我在此设置here中所述。
