Update:
Mocha is the best in my opinion.
What is the experience with these frameworks?
I played with expresso which is pretty cool testing framework which also has test-coverage. It has been created by TJ Holowaychuk who is also the creator of Express.js (insanely fast (and small) server-side JavaScript web development framework built on Node.js and Connect). I recently saw that he also has a cool library called should.js which can be used together with Expresso for a even better testing experience.
Obviously, the ability to run in the
browser would be a big bonus
I don’t believe it can run in the browser, but I also don’t get why you would want to run it inside the browser?
but I’m mainly interested in Node.js.
Something with a heavily asynchronous
slant would be great.
Quote from the expresso:
The argument passed to each callback
is beforeExit, which is typically used
to assert that callbacks have been
invoked.
You can use beforeExit to test asynchronous functions.
TIP: Follow TJ Holowaychuk on GitHub, because he creates very good open-source code.
