Rails Cucumber如何在进入编辑页面之前检查用户是否已登录

Question

I have developed Rails application where user needs to be logged in to edit character he created earlier. Now I am trying to test my edit character function and I have created edit character scenario. Here is my files:

features/character.feature

     Feature: Character

       @javascript
       Scenario: Visiting characters listing page
         Given I am a new, authenticated user
         When I go to characters index page
         Then I should see characters listing page   

characters_steps.rb

   Given /^I am a new, authenticated user$/ do
     email = 'ademimisel@gmail.com'
     password = 'pass1234'

     visit '#/login'
     fill_in 'email', :with => email
     fill_in 'password', :with => password
     click_button "Sign in"
   end

  When(/^I go to characters index page$/) do
    visit '#/'
    expect(page).to have_content("Characters")
  end

  Then(/^I should see characters listing page$/) do
    pending # Write code here that turns the phrase above into concrete     actions
  end

When I run, first step pass successfully but second not, because cucumber not register that sign up was successfully done and page are not redirected to edit page

Answer 1

Assuming that you have created a user in the database matching the username and password, all you need is a final line in your "I am a new, authenticated user" step that checks for something that is shown on the page after logging in.

Given /^I am a new, authenticated user$/ do
  email = 'ademimisel@gmail.com'
  password = 'pass1234'

  visit '#/login'
  fill_in 'email', :with => email
  fill_in 'password', :with => password
  click_button "Sign in"
  expect(page).to have_text("You are now logged in") # or whatever message is displayed to indicate successfull login - if using RSpec
  # page.assert_text("You are now logged in") # if not using RSpec
end

Answer 2

If a user needs to be logged in before they can do something then you need to have the ability to 'register' as a user 'before' you can implement this scenario. Assuming you have done this you should be able to write something like

Given I am registered
And I am logged in
When I view characters
Then I should see a list of characters

You can implement the steps as follows

Given 'I am registered' do
  @i = create_registered_user
end

Given 'I am logged in' do
  login as: @i
end

and implement these using a step helper module

module RegistrationStepHelper
  def login(as:)
    ...

  def create_registered_user
    ...

end
World RegistrationStepHelper

You should extract the code you've previously written to do these tasks and use that in these methods.

Now if you haven't got this sort of capability from the code you have already written you need to create it and use it to ensure that there is a registered user in the database before you login to view your characters.

From your question and the code you've posted there is no indication that such a user is in the database. Each scenario starts with an empty database and your scenario is not registering a user.
