jQuery chain testing with sinonJS

If you want to test something like this:


You can easily try this:

// Fake jQuery methods
var jQueryMethods = { toggleClass: empty, siblings: empty };

// First the methods that can be chained
sinon.stub(jQueryMethods, 'toggleClass').returns(jQueryMethods);
sinon.stub(jQueryMethods, 'siblings').returns(jQueryMethods);

// Then all jQuery function
sinon.stub(window, '$').returns(jQueryMethods);

And now you have full test-ready faked jQuery methods!

thanks for MS

Very helpful!
But one thing: You shouldn't use "toggleClass", will you? Apart from it - .removeClass

Thanks for this! Saved me a big headache when I switched my Express response calls from the deprecated res.json(status, body) calls to the new res.status(status).json(body) format. Cheers!
