support co-based generators

it('should work', function* () {
  yield wait(1)
})

meh :p easy to delegate that and just do

it('should work', function(done){
  co(function *(){
    yield whatever;
  })(done)
})

similar to the promise argument, I think leaving mocha at the simplest level with regular old callbacks is the best way to go

[jonathanong]

:( yeah it's good to be consistent and only supporting callbacks and rejecting all control flow libs.

I agree

It may be a stupid question - but how do I have to call mocha from the command-line to support generators? If I simply run mocha as usual, I get an error telling me about an unexpected * at the generator function that I hand over to co.

Any advice?

@goloroden

mocha --harmony should do it :)

[goloroden]

Ah, okay, thanks a lot :-)). This option doesn't show up when running mocha --help, but it works perfectly :-).

Currently the best way seems to be:

it('should work', function(){
  return co(function *(){
    yield whatever;
  });
})

@schickling you can use something like co-mocha to avoid using co on every test.
