Correct way to pass index of params Rspec test

Question

I have the following search function defined in my model:

class CoffeeType < ActiveRecord::Base
  has_many :coffee_items

   def self.search(search)
    if search
      where('name LIKE ?', "%#{search}")
    else
      where(nil)
    end
  end 
end

and have the following RSpec test:

 describe "GET index with serach params" do
       it 'renders a list of Coffee Types' do
         get :index, {search: "Ame"}, valid_session
         assigns(:coffee_types).count.should eq(2)
       end
    end

This is probably pretty much trivial and am not seeing the bigger picture here.

See here for an explanation of the default rspec use_transactional_fixtures setting:

Unless you've changed this configuration, your database is reset after every example. So you need to actually set up the initial state in the example/example group. In your case that might look something like:

describe "GET index with serach params" do
  before :each do
    # create two coffee_types that should be found by searching for "Ame" and
    # one that shouldn't
    2.times { FactoryGirl.create :coffee_type }
    FactoryGirl.create :coffee_type, name: "Espresso" 
  end  

  it 'renders a list of Coffee Types' do
    get :index, {search: "Ame"}, valid_session
    assigns(:coffee_types).count.should eq(2)
  end
end

Edit: Duh! Actually, the code in your model method is incorrect. You've only got the % wildcard before the search term. Change that line to:

where('name LIKE ?', "%#{search}%")
