I can't figure out why my example fails sometimes and sometimes not:
describe ClientsController do
let(:admin) { create(:admin) }
before(:each) { sign_in admin }
describe 'GET #index' do
Client.delete_all
let!(:clients) { Array.new(3) { create(:client) } }
it "populates an array of all clients" do
get :index
expect(assigns(:clients)).to match_array(clients)
end
it "renders the :index template" do
get :index
expect(response).to render_template :index
end
end
end
I set up DatabaseCleaner as follows in spec_helper:
config.before(:suite) do
DatabaseCleaner.clean_with(:truncation)
end
config.before(:each) do
DatabaseCleaner.strategy = :transaction
end
config.before(:each, js: true) do
DatabaseCleaner.strategy = :truncation
end
config.before(:each) do
DatabaseCleaner.start
end
config.after(:each) do
DatabaseCleaner.clean
end
and set up fixtures to false as well (spec_helper):
config.use_transactional_fixtures = false
No matter if I keep the line or not:
Client.delete_all
it fails the first time (when I run all the tests) and passes when I run
the spec separately.
I also defined a shared_db_connection in support folder:
class ActiveRecord::Base
mattr_accessor :shared_connection
@@shared_connection = nil
def self.connection
@@shared_connection || retrieve_connection
end
end
ActiveRecord::Base.shared_connection = ActiveRecord::Base.connection
