获取用于业力单元测试的json文件

问题描述

我想在单元测试中获取一个JSON文件，因为我需要在测试中使用它，但我不知道如何包含该文件

I want to get a JSON file in my unit test because I need to have it for my tests but I dont know how I can include the file

我用业力和茉莉花进行了测试.我的项目是使用Angular 2创建的.

I run my test with karma and Jasmine. And my project is created with Angular 2.

我的JSON文件的名称是'www/assets/mocks/emptyCalendarData.JSON'.

The name of my JSON file is 'www/assets/mocks/emptyCalendarData.JSON'.

有人知道我如何将JSON文件包含到规范文件中吗?

Does someone know how I can include a JSON file into a spec file?

谢谢

更新

我尝试使用HTTP get，但是后来我有了系统

I tried to use HTTP get but then I got a system

let calendarData: Calendar;
http.get('www/assets/mocks/emptyCalendarData.json')
    .map(res => res.json())
    .subscribe(
        data => calendarData = data,
        err => console.log(JSON.stringify(err))
    );

然后我收到此错误:

ERROR: Error{stack: null, originalErr: TypeError{stack: 'mergeOptions
get

推荐答案

有很多方法可以做到这一点:

There are many ways to do that:

• 导入json(如果它在您的应用程序内部):import * as json from './test'; //will import test.json
• 使用Http下载文件并执行map(res=>res.json())
• 对于webpack，请使用json-loader插件:var json = require('./my.json')
• 对于gulp/grunt等，您可以编写代码生成器

• import json if it is inside of your app: import * as json from './test'; //will import test.json
• download file using Http and do map(res=>res.json())
• for webpack use json-loader plugin: var json = require('./my.json')
• for gulp/grunt etc. you could write code generator
