如何在javascript单元测试中模拟数据？

Question

I m using Jasmine library for unit testing my javascript code. I have tried to find a way to mock data, but I didn't found a good solution. Information on how to mock data and libraries which mock data automatically with an example would help me a lot. Thanks in advance.

Sinon.js is a generic, framework-agnostic library that enables you to mock entirely data in the browser (by faking XMLHttpRequest Object). You can use it with jasmine eg this way . What this library does is extending jasmine assertions with native sinon features, such as called , threw , returned , etc. See them all here .

In Sinon, you should take a look at fakeServer .

Additionally, here you've got a working example of sinon's fakeServer along with jasmine runner written by the author of Sinon.js: https://gist.github.com/cjohansen/739589 :)
