I'm using RSpec (through the gem rspec-rails) for testing and developing
my application.
Then, I've tried to "test" a controller and run up against a something
that in last, I'm not understanding: post and get methods.
I've searched them in RoR doc, but their's not documented.
In my route file:
controller :sessions do
post 'login', action: :login_create
get 'login', action: :login
get 'logout', action: :logout
end
At the beginning, I was thinking that post will simulate an http post
request at the specified url, while get a http get one, so I've writed:
describe "POST 'login'" do
it "returns http success" do
post 'login'
response.should be_success
response.should render_template 'sessions/login_create'
end
end
But this will load the login action and not the login_create! After a
lot of searching and trying, I've wrote:
post :login_create
... And it works as expected. However, after that I've tried:
get :login_create
... And this works also! O_o
So, what this kind of methods really do and how are intended to be used?
The problem isn't in the route, but in the strange behavior of get and
post, instance methods of ActionController::TestCase::Behavior
My rspec tests seem to work as you would expect. I used a controller
named Dogs to test the routes:
require 'spec_helper'
describe "Dogs Pages" do
describe "POST to /login" do
it "returns http success" do
post '/login'
response.should be_success
response.should render_template 'dogs/login_create'
response.body.should include('hello world')
end
end
describe "GET to /login" do
it "should have h1 of 'Doggie'" do
visit '/login'
page.should have_selector('h1', text: "Login")
end
end
It also explained in "HTTP helper methods" paragraph of the linked api.
