我正在学习 Rails 教程，并且一直非常严格地遵循它。但是，我的 user_pages_spec.rb 测试重置了开发数据库。因此，每当我运行测试时，我都会丢失测试前的所有当前数据。我的猜测是问题出在第 11 行，但我不太确定。非常感谢任何帮助，谢谢:)

这是我的 user_pages_spec.rb 文件：

require 'spec_helper'

describe "UserPages" do

subject { page }

describe "index" do
    let(:user) { FactoryGirl.create(:user) }

    before(:all) { 30.times { FactoryGirl.create(:user) } }
    after(:all) { User.delete_all }

    before(:each) do
        sign_in user
        visit users_path
    end

    it { should have_selector('title', text: 'All users') }
    it { should have_selector('h1', text: 'All users') }

    describe "pagination" do
        it { should have_selector('div.pagination') }

        it "should list each user" do
            User.paginate(page: 1).each do |user|
                page.should have_selector('li', text: user.name)
            end
        end
    end

    describe "as an admin user" do
        let(:admin) { FactoryGirl.create(:admin) }
        before do
            sign_in admin
            visit users_path
        end

        it { should have_link('delete', href: user_path(User.first)) }
        it "should be able to delete another user" do
            expect { click_link('delete') }.to change(User, :count).by(-1)
        end
        it { should_not have_link('delete', href: user_path(admin)) }
    end
end

describe "signup page" do
    before { visit signup_path }
    let(:submit) { "Create my account" }

    it { should have_selector('h1', text: 'Sign up')}
    it { should have_selector('title', text: full_title('Sign up'))}

    describe "with invalid information" do
        it "should not create a user" do
            expect { click_button submit }.not_to change(User, :count)
        end

        describe "after submission" do
            before { click_button submit }

            it { should have_selector('title', text: 'Sign up') }
            it { should have_content('error') }
        end
    end

    describe "with valid information" do
        before do
            fill_in "Name", with: "Example User"
            fill_in "Email", with: "user@example.com"
            fill_in "Password", with: "foobar"
            fill_in "Confirmation", with: "foobar"
        end

        it "should create a user" do
            expect { click_button submit }.to change(User, :count).by(1)
        end

        describe "after saving the user" do
            before { click_button submit }
            let(:user) { User.find_by_email('user@example.com') }

            it { should have_selector('title', text: user.name) }
            it { should have_selector('div.alert.alert-success', text: 'Welcome' ) }
        end
    end
end

describe "profile page" do
    # Code to make a user variable
    let(:user) { FactoryGirl.create(:user) }
    before { visit user_path(user) }

    it { should have_selector('h1', text: user.name) }
    it { should have_selector('title', text: user.name) }
end

describe "edit" do
    let(:user) { FactoryGirl.create(:user) }
    before do
        sign_in user
        visit edit_user_path(user)
    end

    describe "page" do
        it { should have_selector('h1', text: "Update your profile") }
        it { should have_selector('title', text: "Edit user") }
        it { should have_link('change', href: 'http://gravatar.com/emails') }
    end

    describe "with invalid information" do
        before { click_button "Save changes" }
        it { should have_content('error') }
    end

    describe "with valid information" do
        let(:new_name) { "New Name" }
        let(:new_email) { "new@example.com" }

        before do
            fill_in "Name", with: new_name
            fill_in "Email", with: new_email
            fill_in "Password", with: user.password
            fill_in "Confirm Password", with: user.password
            click_button "Save changes"
        end

        it { should have_selector('title', text: new_name) }
        it { should have_selector('div.alert.alert-success') }
        it { should have_link('Sign out', href: signout_path) }
        specify { user.reload.name.should == new_name }
        specify { user.reload.email.should == new_email }
    end
end 
end

这是我的 database.yml 文件：

# PostgreSQL. Versions 8.2 and up are supported.

# Install the pg driver:
#   gem install pg
# On Mac OS X with macports:
#   gem install pg -- --with-pg-config=/opt/local/lib/postgresql84/bin/pg_config
# On Windows:
#   gem install pg
#       Choose the win32 build.
#       Install PostgreSQL and put its /bin directory on your path.
#
# Configure Using Gemfile
# gem 'pg'

development:
  adapter: postgresql

  # Connect on a TCP socket. Omitted by default since the client uses a
  # domain socket that doesn't need configuration. Windows does not have
  # domain sockets, so uncomment these lines.

  # Schema search path. The server defaults to $user,public

您需要单独的数据库用于开发和测试环境。例如：

development: &BASE
  adapter: postgresql
  encoding: unicode
  database: rails_development
  pool: 5
  username: postgres
  password: pwpwpwpw

test: &test
  <<: *BASE
  database: rails_test

production:
  <<: *BASE
  database: rails_production

cucumber:
  <<: *test
