How Can I inveke a code example in another one

Testing RSpec
1

Hi,
I’m new to rspec.
How could I transform the Unit:Tests code like

def test_logout
login
get :logout
assert_not_logged_in
end
def assert_not_logged_in
assert_block { session[“user”].nil? }
end

that a test method invoke another test method,to repec code.

Should I put them in one code example? or there is other way?

Thanks!

Instead of assertions, RSpec uses expectations, like this:

describe “GET /logout” do
it “removes the user from the session” do
login
get :logout
session[“user”].should be_nil
end
end

An expectation has two parts: should() or should_not(), and a matcher.
In this case, be_nil() is a matcher that’s built in to RSpec. You can
also write your own, using RSpec’s matcher DSL:

Spec::Matchers.define :be_logged_out do
match do |session|
session[“user”].nil?
end
end

describe “GET /logout” do
it “ends the user session” do
login
get :logout
session.should be_logged_out
end
end

Or you could write a be_logged_in matcher and use it with should_not,
like this:

Spec::Matchers.define :be_logged_in do
match do |session|
!!session[“user”]
end
end

describe “GET /logout” do
it “ends the user session” do
login
get :logout
session.should_not be_logged_in
end
end
