Edit your new class in Rails.root/lib/swat/AppTestWorld.rb Add Methods:

  def init_situation
    if @options[:john]
      User.create(email: 'john.smith@gmail.com', full_name: 'John Smith')
    end

    if @options[:josh]
      User.create(email: 'josh.doe@gmail.com', full_name: 'Josh Doe')

Configure RSpec, add lines tp Rails.root/spec/spec_helper.rb

require 'sw2at-tw'
require_relative '../lib/swat/AppTestWorld'
Swat::TestWorld.setup(config, klass: AppTestWorld)

Use helpers in your test. Rails.root/spec/models/user_spec.rb

require 'rails_helper'

RSpec.describe User, type: :model do

  context 'No Swat Options' do
    init_tw

    it 'should have Users' do
      expect(User.count).to eq(0)
    end

  end

  context 'John created' do
    init_tw( john: true )

    it 'should have Users' do

      expect(User.count).to eq(1)
      john = User.where(email: 'john.smith@gmail.com').take
      expect(john.full_name).to eq('John Smith')
    end

  end

  context 'John & Josh' do
    init_tw( john: true, josh: true )

    it 'should have Users' do
      expect(User.all.map(&:full_name)).to eq([ 'John Smith', 'Josh Doe' ])
    end
  end
  
  context 'Methods' do
    init_tw

    it 'should call Test World methods' do
      @tw.some_very_specific_logic
    end

  end

Run RSpec

rspec

• Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
• Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
• Fork the project.
• Start a feature/bugfix branch.
• Commit and push until you are happy with your contribution.
• Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
