[rspec-users] Do people write specs for the code in their steps? How?

This is one thing I don't get. I just started implementing steps, but
I feel like THAT code is all completely untested. I don't know if my
regular expression is correct, I don't know if it does what I think it
should do. What I really want to do is write something like this:
describe "steps for withdrawing money"
describe "Given user has a balance"
cucumber "Given user has $50 dollars"
it "should match a particular step"
it "should create an account"
it "should set the account balance to $50"
But is there such a "cucumber" method? And how do you check that your
regular expressions are going to the right place?
Maybe the best thing to do is write your cucumber steps like this:
user_has_a_balance = /user has $(.*) dollars/
Given user_has_a_balance do |balance|
And then in your spec you can do:
user_has_a_balance.match("user has $20 dollars").should_not == nil
How do people write specs for their cucumber steps? And if you don't
write specs, how do you live with the uncertainty?
