Overview

Adds the following RSpec matchers:

• Associations:

  Verify that the association has been defined. (doesn't verify that the association works!)

  object.should have_many(:association)
  example: @post.should have_many(:comments)
  TM snippet: [mshm + tab] (Model Should Have Many)
  
  object.should belong_to(:association)
  example: @comment.should belong_to(:post)
  TM snippet: [msbt + tab]
  
  object.should have_one(:association)
  user.should have_one(:social_security_number)
  TM snippet: [msho + tab]
  
  object.should have_and_belong_to_many(:association)
  project.should have_and_belong_to_many(:categories)
  TM snippet: [mshabtm + tab]
  

• Validations:

  Verify that a validation has been defined. (doesn't test the validation itself)

  object.should validate_presence_of(:attribute)
  TM snippet: [msvp + tab]
  
  object.should validate_confirmation_of(:attribute)
  TM snippet: [msvc + tab]
  
  object.should validate_uniqueness_of(:attribute)
  TM snippet: [msvu + tab]
  
  object.should validate_length_of(:attribute, :within => 5..10)
  object.should validate_length_of(:attribute, :is => 5)
  TM snippet: [msvl + tab]
  

• Observers:

  Verify that the observer is observing a class. (doesn't verify that the observation works)

  object.should observe(:model)
  example: GroupObserver.should observe(Group)
  

• Views:

  Verifies that the views contains some tags.

  response.should have_form_posting_to(url_or_path)
  TM snippet: [hfpt + tab]
  
  response.should have_form_putting_to(url_or_path)
  
  response.should have_text_field_for(:attribute)
  TM snippet: [htff + tab]
  
  response.should have_label_for(:attribute)
  TM snippet: [hlf + tab]
  
  response.should have_password_field_for(:attribute)
  TM snippet: [hpff + tab]
  
  response.should have_checkbox_for(:attribute)
  TM snippet: [hcf + tab]
  
  response.should have_submit_button
  TM snippet: [hsb + tab]
  
  response.should have_link_to(url_or_path, "optional_text")
  TM snippet: [hlt + tab]
  

  • nested view tests:

    for instance:

    response.should have_form_posting_to(url_or_path) do
      with_text_field_for(:attribute)
    end
    
    with_text_field_for(:attribute)
    TM snippet: [wtff + tab]
    
    with_label_for(:attribute)
    TM snippet: [wlf + tab]
    
    with_password_field_for(:attribute)
    TM snippet: [wpff + tab]
    
    with_checkbox_for(:attribute)
    TM snippet: [wcf + tab]
    
    with_submit_button
    TM snippet: [wsb + tab]
    
    with_link_to(url_or_path, "optional_text")
    TM snippet: [wlt + tab]
    

Usage:

In your view spec:

it "should render new form" do
    render "/users/new.html.erb"

    response.should have_form_posting_to(users_path) do
      with_text_field_for(:user_name)
      with_text_area_for(:user_address)
      with_text_field_for(:user_login)
      with_text_field_for(:user_email)
      with_submit_button
    end
end

In your model spec:

describe User do
  before(:each) do
    @user = User.new
  end

  it "should have many posts" do
    @user.should have_many(:posts)
  end

  it "should belong to a group" do
    @user.should belong_to(:group)
  end

  it do
    @user.should validate_presence_of(:email)
  end

  it do
    @user.should validate_uniqueness_of(:email)
  end

  it do
    @user.should validate_uniqueness_of(:login)
  end

  it do
    @user.should validate_presence_of(:login)
  end

  it do
    @user.should validate_presence_of(:name)
  end

  it do
    @user.should validate_length_of(:password, :between => 4..40)
  end

  it do
    @user.should validate_confirmation_of(:password)
  end

end
