RSpec failling in email should not be valid - ruby-on-rails

Question

I'm new to all this rails/rspec and so on, so im trying to follow some tests that I had found in the project that i'm working and make sense, they were generated by scaffold but the app is very different and no tests were updated so im re-doing every test.
The problem is when I try to validate that invalid emails should make the user invalid it fails.
I know that it's ok because I already done tests and they pass without no problem.
It is possible that I'm looking at this the wrong way but ...
User_spec
describe "when email format is invalid" do
it "should be invalid" do
addresses = %w[user#foo,com user_at_foo.org example.user#foo.
foo#bar_baz.com foo#bar+baz.com]
addresses.each do |invalid_address|
#user.email = invalid_address
#user.should_not be_valid
end
end
end
User_test
test "fail save new user with an corrupt email" do
user = User.new
user.name = 'Someone Name'
user.password = '12345678'
user.email = 'Someone Name#gmail..com'
assert !user.save , "User was saved with an corrupt email"
end
The validation is done by devise and the failure message is "expected valid? to return false, got true"
---- edit ---
My user setup
...
describe User do
before :each do
#user = User.new(name: "Name of Names", email:"someone1#somewhere.com",password: "foobarfoobar", password_confirmation: "foobarfoobar" )
end
...

You could do something along the lines of this:
context "validations" do
describe "email" do
subject { FactoryGirl.create(:user, email: email) }
context "with an valid address" do
let(:email) { "valid#email.com" }
it { should be_valid }
end
context "with an invalid email address" do
let(:email) { "invalid.email.com" }
it { should_not be_valid }
end
end
end
So I'm assuming you are using FactoryGirl to create an valid user object. Just create new tests per invalid email, this way you can see which tests are passing and which aren't. Then you could TDD your way to green.
