Generally speaking, the controller will be pointing towards a view using either render or redirect_to: 

1. render: tells Rails which view to show; doesn't run target action's code
2. redirect_to: tells Rails that the browser needs to send a new request to whatever the redirect_to value is; runs target action's code

Render vs. redirect_to can be confusing; here's a clear snippet of code from the Ruby on Rails Guide that should clarify

'''
def index
  @books = Book.all

=Navigating=
    visit('/projects')
    visit(post_comments_path(post))

=Clicking links and buttons=
    click_link('id-of-link')
    click_link('Link Text')
    click_button('Save')
    click('Link Text') # Click either a link or a button
    click('Button Value')
