Scenarios
with one validation error
Given
a file named "spec/models/widget_spec.rb" with: 
require "spec_helper"

class ValidatingWidget < ActiveRecord::Base
  self.table_name = :widgets
  validates_presence_of :name

  # In Rails 4, mass assignment protection is implemented on controllers
  attr_accessible :name if Rails.version < '4'

  validates_length_of :name, :minimum => 10, :on => :publication
end

describe ValidatingWidget do
  it "fails validation with no name (using error_on)" do
    expect(ValidatingWidget.new).to have(1).error_on(:name)
  end

  it "fails validation with no name (using errors_on)" do
    expect(ValidatingWidget.new).to have(1).errors_on(:name)
  end

  it "fails validation with no name expecting a specific message" do
    expect(ValidatingWidget.new.errors_on(:name)).to include("can't be blank")
  end

  it "fails validation with a short name (using a validation context)" do
    expect(ValidatingWidget.new(:name => "too short")).
      to have(1).errors_on(:name, :context => :publication)
  end

  it "passes validation with a longer name (using a validation context)" do
    expect(ValidatingWidget.new(:name => "a longer name")).
      to have(0).errors_on(:name, :context => :publication)
  end

  it "passes validation with a name (using 0)" do
    expect(ValidatingWidget.new(:name => "liquid nitrogen")).to have(0).errors_on(:name)
  end

  it "passes validation with a name (using :no)" do
    expect(ValidatingWidget.new(:name => "liquid nitrogen")).to have(:no).errors_on(:name)
  end
end
When
I run rspec spec/models/widget_spec.rb
Then
the examples should all pass
