capybara with rspec visting wrong controller - ruby-on-rails

Question

I am trying to test my controller by filling some values.i have placed my controller spec file under spec/feature. But my visit is not properly working, it is visiting wrong controller.
My controller spec file is
require 'spec_helper'
describe ApplicationsController, :type => :controller do
render_views
#the problem is - we need to test criminal record data block from saferent response
#this guy edwin avila is test input provided by saferent
describe "GET 'new'" , :type => :request do
before do
visit '/TestApplication'
fill_in 'application[applicants_attributes][0][first_name]', :with => 'Rose'
click_link_or_button 'sbmt'
end
it 'has 200 status code if logged in' do
expect(response.status).to eq(200)
end
end
end
My Gem file is

Capybara's visit method won't work for that file path (assuming you're trying to get to the root of your application). Try something like
visit root_path
I'd recommend checking out the documentation at http://jnicklas.github.com/capybara
