On of the things I've noticed with ScrewUnit is to quote the ScrewUnit wiki:
"The dynamic nature of JavaScript makes mocking frameworks mostly
unnecessary"
A small but interesting difference from using Ruby, Rspec and its
built-in mocking framework.

Hi
Hope this isn't OT. I'm currently contemplating using the Dojo[1]
JavaScript framework, and I suspect it's powerful enough that using
Cucumber features and Celerity alone will quickly leave me wanting
lower-level unit specs for the JS.
So I just wondered if anyone here has used Screw.Unit[2], and if so,
how does it compare to RSpec? It seems to offer many of the features
of RSpec (with the notable exception of shared behaviours).
I've been using it a bunch, and I must say that so far I've really
enjoyed it. Here are the downsides that I've noticed:
1. It's much more verbose, and doesn't read quite as cleanly as
rspec. Instead of foo.should == "bar", you'll end up with:
expect(foo()).to(equal, bar());
Which just gets a bit syntax heavy. I'm sure that they didn't want to
polute the global namespace, but maybe a function like this might
solve the problem:
Object.prototype.should = function(obj) {
expect(this).to(equal, arg);
};
2. The matchers just aren't there the way they are for rspec. This
can make a big difference to code readability. Obviously, you could
build them yourself. (This is just a matter of time, and standing on
the shoulders of giants sort of thing).
3. I haven't looked very hard, but I haven't found a plain text
runner yet. Obviously it's going to need a browser if you're planning
on doing DOM interaction (which is very easy). For me, though, a
plain text runner would be awsome.
