Just getting started with factory girl, and I’ve come across a problem with sequencing: Specifically, it doesn’t increment. I’ve tried changing the database type, updating from factory_girl 1.3.2 to 2.0.0.beta1 (And factory_girl_rails from 1.0 to 1.1.0.beta1), tried recreating the database, but same problem – the sequence won’t increment and I get a validation error after the first time I insert a unique field.

Any assistance much appreciated. Code & trace stack below:

/spec/models/user.rb

require 'spec_helper'

describe User do   describe "test user factory is correct" do
    user = Factory(:user)

    it "should have an email ending in example.com" do
      #user.email.should match "test2@example.com"
    end

    it "should have a password of foobar" do
      user.password.should == 'foobar'
    end

    it "should have a password confirmation field of foobar" do
      user.password_confirmation.should == 'foobar'
    end
    end

end

/spec/factories/user.rb

Factory.define :user do |f|
    f.sequence(:email) { |n| puts "Email ##{n}"; "factory_#{n}@example.com" }
    f.password 'foobar'
    f.password_confirmation { |p| p.password }
end

Trace:

    Your issue isn’t with factory girl. When instantiating “user” you need to do it from inside a before block so that a new user gets created for each test being run. The user variable should also be an instance variable (i.e. prefixed with @)

    require 'spec_helper'

describe User do   

  describe "test user factory is correct" do

    before(:each) do
      @user = Factory(:user)
    end

    it "should have an email ending in example.com" do
      @user.email.should match "test2@example.com"
    end

    it "should have a password of foobar" do
      @user.password.should == 'foobar'
    end

    it "should have a password confirmation field of foobar" do
      @user.password_confirmation.should == 'foobar'
    end

  end

end
