[rspec-users] [Newbie's Doubt] Model's Tests

[Luciano Borges]

I'm studying Rspec and doing some model's tests.

I have a table with a field which must have two characters, the field
should not be empty and can not be repeated.

My doubts is with #.

describe State do
  context "validations" do

    it "The abbreviation should not be empty" do
      subject.abbreviation = nil
      subject.should_not be_valid
    end

    *# I can do like example below or I have to break in parts?*

    it "The abbreviation  should have 2 characters" do
      subject.abbreviation = "BA"
      subject.should be_valid

      subject.abbreviation = "B"
      subject.should_not be_valid

      subject.abbreviation = "BAA"
      subject.should_not be_valid
    end

    it "The abbreviation can not be repeated" do

*     # I don't know how to do!*

    end
  end
end

Thanks,
Luciano
