Unable to mock when using isomorphic-fetch

[wheresrhys]

I don't see where isomorphic fetch is being required in your code. Have you pushed all your files to github?

[vyorkin]

the isomorphic-fetch is defined globally using the webpack ProvidePlugin

[vyorkin]

here https://github.com/vyorkin-play/fetch-mock-example/blob/master/webpack.config.js#L30. I did it this way because the readme says:

When using isomorphic-fetch or node-fetch ideally fetch should be added as a global

[wheresrhys]

require('isomorphic-fetch') will already add fetch as a global (https://github.com/matthew-andrews/isomorphic-fetch/blob/master/fetch-npm-browserify.js#L1), so no need for a webpack loader. To avoid having to require isomorphic-fetch in every file you could npm install whatwg-fetch (this is the polyfill isomorphic fetch is built around) then in karma.conf.js include the fetch polyfill before your tests.

I'll add some clearer usage guides to the docs sometime

thanks @wheresrhys! got it working, btw I think I've found a typo here, as I can see it returns an object (not array) if no argument is given: https://github.com/wheresrhys/fetch-mock/blob/master/README.md#callsmatcher
