Each example (`it`) is run in isolation from the other examples -- there is no
shared state. This keeps things clean and easy to understand. In your example,
just add a method for "signing up":
describe "User pages" do
subject { page }
describe "sign up" do
describe "with valid information" do
before do
fill_in "Name", with: "Mickey Mouse"
fill_in "Email", with: "[email protected]"
fill_in "Password", with: "m1ck3y"
fill_in "Confirmation", with: "m1ck3y"
end
def click_sign_up_button
click_button "Sign up"
end
it "should create a user" do # block 1
expect { click_sign_up_button }.to change(User, :count).by(1)
end
describe "after saving the user" do #block 2
before { click_sign_up_button }
let(:user) { User.find_by_email('[email protected]') }
it { should have_selector('title', text: user.name) }
it { should have_link('Sign out') }
end
end
