Fixing --serial command. TODO added

[AnthonyAkentiev]

When running tests with --serial parameter -> causes error because assert object is NULL.

Also i've found 2nd bug with --serial execution.
In case test is not calling 'beforeExit' -> test would always fail with "test timed out" error. I haven't fixed that yet, but wrote comment.

might want to check out mocha this lib is just sticking around for historical reasons but it was a quick hack

[AnthonyAkentiev]

Hehe. Yeah, i saw that comment. Ok, i will check Mocha. I kind of like expresso, it is so easy to use... Can you merge my pull-request?

+1

mocha is equally easy to use, this lib is deprecated

[bithavoc]

@visionmedia if the library is deprecated, we should add this to Readme.md.

In fact, I'm actually using mocha and just googled assert.isDefined and expresso came up first, would you consider adding these additional assertions to mocha?

The code is right here: https://github.com/visionmedia/expresso/blob/master/bin/expresso#L312

I can send a pull request to mocha.

it says to use mocha in the readme. Nah there's a lot of different libs that can be used with mocha for assertions, assert(null != foo) from core's assert lib works for that though
