Module: Resubject::Rspec

Defined in:
lib/resubject/rspec.rb

Overview

RSpec configuration and helpers

This helper automatically creates ‘subject` and `template` variables for RSpec when testing your presenter.

To get this working, create a spec file in ‘spec/presenters` and require `resubject/rspec`. You only need to define the object under test by creating a `let(:object)`, like so:

Examples:

Isolated spec for MyPresenter


# spec/presenters/my_presenter_spec.rb
require 'resubject/rspec'
require 'presenters/my_presenter'

describe MyPresenter do
  let(:object) { mock :presented }

  it 'has full name' do
    object.stub(first: 'My', last: 'Name')
    expect(subject.name).to eq 'My Name'
  end
end
