Having an argument in your it function (done in the code below) will cause Jasmine to attempt an async call.
//this block signature will trigger async behavior.
it("should work", function(done){
//...
});
//this block signature will run synchronously
it("should work", function(){
//...
});
It doesn’t make a difference what the done argument is named, its existence is all that matters. I ran into this issue from too much copy/pasta.
The Jasmine Asynchronous Support docs note that argument (named done above) is a callback that can be called to let Jasmine know when an asynchronous function is complete. If you never call it, Jasmine will never know your test is done and will eventually timeout.
