如何在Angular 2 Karma茉莉测试中从JSON文件加载模拟数据? [英] How to load mock data from JSON file in Angular 2 karma jasmine test?
问题描述
我为 angular 2 ,
我们遇到了在单独的JSON文件中模拟数据的要求,因为数据量很大(希望确保代码的整洁度).为此,我进行了很多搜索,但没有找到合适的解决方案.
And we came across requirement to mock data in separate JSON file as data is huge (want to make sure code cleanness). For this I searched a lot but didn't find proper solution.
我们已经使用 MockBackend 来模拟HTTP服务,因此我们不能使用angular的HTTP服务来加载JSON,因为最终请求将传递给MockBackend.
We already mocking HTTP service using MockBackend, So we can't use HTTP service of angular to load JSON as it eventually request will go to MockBackend.
那么还有其他方法可以不使用任何第三方库吗? jasmine-jquery还是Karma-jasmine-preprocessor? 更多种Angular JS 2方式 .
So is there any another way without using any third party lib like jasmine-jquery or Karma-jasmine-preprocessor ? More kind of Angular JS 2 way.
推荐答案
我遇到了同样的问题!
最后,我意识到仅在TypeScript中直接使用require()
函数就可以了. Node和@ types/node支持它,否则有些需要声明require类型.
Finally, I realized that just using the require()
function directly in TypeScript works just fine. It is supported by Node and @types/node, otherwise some need to declare require types.
因此要在Angular 2 Karma Jasmine测试中从JSON文件加载模拟数据,请执行以下操作:
So to load mock data from JSON file in Angular 2 Karma Jasmine test, go for:
const data: any = require('../../assets/mock-data.json');
