我很难为
angularjs(v1.4.9)应用程序创建适当的单元测试,该应用程序包含
javascript文件(带有jasmine测试)和typescript文件(根本没有测试,现在我尝试使用Mocha,但它可以是任何框架).
因此它混合和没有模块的旧angularjs,我决定将所有.ts编译成一个bundle.js文件,因为避免了文件排序问题(当我每个.ts有单个.js文件并将其注入gulp任务时发生的index.html).
我的tsconfig.js：
{
"compileOnSave": true,"compilerOptions": {
"noImplicitAny": false,"removeComments": false,"outFile": "./wwwroot/bundle.js","sourceMap": true,"inlineSources": true,"module": "amd","moduleResolution": "node","target": "es5","sourceRoot": "./wwwroot"
},"include": [
"wwwroot/app/**/*"
],"exclude": [
"node_modules/**/*","tests/**/*"
]
}
测试类的示例：
///<reference path="../models/paymentCondition.model.ts"/>
///<reference path="../../../../../node_modules/@types/angular/index.d.ts"/>
'use strict';
module PaymentCondition {
export class ConnectedCustomersListController {
name: string;
static $inject = ['paymentCondition'];
constructor(private paymentCondition: PaymentConditionModel) {
this.name = paymentCondition.Name;
this.bindData();
}
bindData() {
// do something
}
}
angular
.module('app.paymentConditions')
.controller('ConnectedCustomersListController',ConnectedCustomersListController);
}
我的模块声明：
///<reference path="../../../../node_modules/@types/angular/index.d.ts"/>
'use strict';
module PaymentCondition {
angular.module('app.paymentConditions',['ui.router','ui.bootstrap']);
}
我正在将这个模块“注入”主模块文件,该文件已经在javascript-App.module.js中：
(function () {
'use strict';
var module = angular.module('app',[
'app.paymentCondition','ui.router','ui.bootstrap',]);
})();
最后我的测试类：
///<reference path="../../../node_modules/@types/angular/index.d.ts"/>
///<reference path="../../../wwwroot/app/domain/paymentConditions/connectedCustomersList/connectedCustomersList.controller.ts"/>
///<reference path="../../../node_modules/@types/angular-mocks/index.d.ts"/>
import { expect } from 'chai';
import "angular-mocks/index";
import * as angular from "angular";
describe("app.paymentConditions.connectedCustomersList",() => {
var mock;
// inject main module
beforeEach(angular.mock.module('app.paymentConditions'));
beforeEach(angular.mock.inject(($controller: ng.IControllerService) => {
mock = {
connectedCustomersListModel: {
columnDefinitions() {
}
},paymentCondition: {},createController(): PaymentCondition.ConnectedCustomersListController {
return $controller<PaymentCondition.ConnectedCustomersListController >('ConnectedCustomersListController',{
connectedCustomersListModel: mock.connectedCustomersListModel,});
}
};
}));
describe("ConnectedCustomersListController",() => {
var controller: PaymentCondition.ConnectedCustomersListController;
beforeEach(() => {
controller = mock.createController();
});
it("should be defined",() => {
expect(controller).not.undefined;
});
});
});
当我尝试使用命令运行mocha测试时：
./node_modules/.bin/mocha --compilers ts:ts-node/register ./tests/**/*.spec.ts
我有这个例外：

我知道这是因为我使用amd模块将我的打字稿编译成一个js文件,但我真的不知道如何修复它.或者,如果它无法修复,也许您有一些建议如何将类型脚本“混合”到现有的AngularJs解决方案.
PS.我使用mocha和支持的typescript编译器,因为我不知道如何使用这种组合运行jasmine测试.

解决方法
Hence it hybrid and an old angularjs without modules
你已经声明你没有使用模块,但实际上你是.
您显示的tsconfig.json表示您已配置TypeScript以将代码转换为AMD模块.此外,您的index.html相应地设置,因为您实际上使用的是AMD加载程序,即RequireJS.
所有这一切都很好.您应该使用模块,并且使用AngularJS这样做不仅可行而且容易.
但是,顺便说一句,ts-node采用了你的TypeScript代码,然后自动转换并运行它.执行此操作时,它会从tsconfig.json加载设置,实例化传递这些设置的TypeScript编译器,编译代码,然后将结果传递给Node.js以便执行.
NodeJS不是AMD模块环境.它不支持AMD,也不提供定义功能.
有几种有效的方法可以执行测试.
一种选择是对ts节点使用不同的配置,具体来说,告诉它输出CommonJS模块而不是AMD模块.这将产生Node.js理解的输出.
就像是
./node_modules/.bin/mocha --compilers ts:ts-node/register --project tsconfig.tests.json
tsconfig.tests.json的样子
{
"extends": "./tsconfig.json","compilerOptions": {
"module": "commonjs","esModuleInterop": true
},"include": ["tests/**/*.spec.ts"]
}
请记住,AMD和CommonJS模块具有不同的语义,虽然您可能永远不会在测试代码中遇到任何差异,但您的代码将使用不同的加载程序进行测试而不是生产代码.
另一种选择是在节点中使用兼容AMD的加载程序来运行测试.您可以使用mocha的–require选项执行此操作.例如
mocha --require requirejs
备注：
您的代码中存在一些错误,即使它们不是问题的直接原因,它们也应该被解决,它们与模块,路径等有关.
>不要使用///< reference path =“...”/>加载声明文件.编译器会自动选择它们.
>不要使用module关键字在TypeScript代码中创建名称空间.这一点很久就被弃用了,因为它引入了术语混淆.请改用namespace关键字.
>永远不要混合模块语法,从’y’导入x,并且///< reference path =“x.ts”/>实际加载代码.
换句话说,在您的测试中,替换
///<reference path="../../../wwwroot/app/domain/paymentConditions/connectedCustomersList/connectedCustomersList.controller.ts"/>
同
import "../../../wwwroot/app/domain/paymentConditions/connectedCustomersList/connectedCustomersList.controller.ts";
立刻！
在此更改后,您的测试将如下所示
import "../../../wwwroot/app/domain/paymentConditions/connectedCustomersList/connectedCustomersList.controller.ts"; import chai from 'chai'; import "angular-mocks/index"; // just like controller.ts import angular from "angular"; const expect = chai.expect;
这很严重.不要考虑,只是这样做.
>考虑将整个代码库转换为适当的模块. AngularJS可以很好地使用这种方法,它可以降低工具链的整体复杂性,同时使您的系统更好地考虑因素,并且您的代码更易于维护和重用.
这个想法最终会改变
namespace PaymentConditions {
angular.module('app.paymentConditions','ui.bootstrap']);
}
至
import angular 'angular';
import uiRouter from 'angular-ui-router';
import uiBootstrap from 'angular-ui-bootstrap';
import ConnectedCustomersListController from './connectedCustomersList/connectedCustomersList.controller';
const paymentConditions = angular.module('app.paymentConditions',[
uiRouter,uiBootstrap
])
.controller({
ConnectedCustomersListController
});
export default paymentConditions;
和你的控制器一起
export default class ConnectedCustomersListController {
static $inject = ['paymentCondition'];
name: string;
constructor(public paymentCondition: PaymentConditionModel) {
this.name = paymentCondition.Name;
this.bindData();
}
bindData() {
// do something
}
}
