stub_model

The stub_model method generates an instance of a Active Model model.

While you can use stub_model in any example (model, view, controller,
helper), it is especially useful in view examples, which are inherently
more state-based than interaction-based.

Scenarios

passing an Active Record constant with a hash of stubs

Given

a file named "spec/models/widget_spec.rb" with:

require "spec_helper"

describe "stub_model(Widget) with a hash of stubs" do
  let(:widget) do
    stub_model Widget, :id => 5, :random_attribute => true
  end
  
  it "stubs :id" do
    widget.id.should eql(5)
  end
  
  it "stubs :random_attribute" do
    widget.random_attribute.should be_true
  end
  
  it "returns false for new_record? if :id is set" do
    widget.should_not be_new_record
  end
  
  it "can be converted to a new record" do
    widget.as_new_record
    widget.should be_new_record
  end
end

When

I run "rspec spec/models/widget_spec.rb"

Then

the output should contain "4 examples, 0 failures"

passing an Active Record constant with a block of stubs

Given

a file named "spec/models/widget_spec.rb" with:

require "spec_helper"

describe "stub_model(Widget) with a block of stubs" do
  let(:widget) do
    stub_model Widget do |widget|
      widget.id = 5
    end
  end
  
  it "stubs :id" do
    widget.id.should eql(5)
  end
end

When

I run "rspec spec/models/widget_spec.rb"

Then

the output should contain "1 example, 0 failures"
