javascript - 使用 Rails 5.1 和 Vue.js 进行 Flaky 系统测试

Question

几天来我一直在尝试对此进行调试，只是无法弄清楚问题出在哪里。我最初认为这是一个顺序依赖，但我不再这么认为了，所以 rspec --bisect=verbose。

我现在倾向于 Devise/Warden 助手无法正常工作，我没有正确设置 capybara /网络驱动程序或其他原因。

这个测试有时会失败:

1. 在重定向时，当从菜单中选择项目以重定向到另一个页面时。例如，在按下“帐户设置”后重定向到“帐户设置”页面。这是我责怪 Devise 助手的地方，因为当我登陆主页时我已经登录，但是当我进入帐户设置时 current_user 返回 nil，因此示例失败它被重定向到登录页面。

这也是特定于测试的，实时代码可以正常运行数月。

系统测试

require 'rails_helper'

RSpec.describe 'home page', type: :system do
  before(:context) do
    WebMock.disable_net_connect!(allow_localhost: true)
  end

  after(:each) do
    Warden.test_reset!
  end

  context 'when not logged in' do
    it 'displays login with discord button' do
      visit '/'

      expect(page).to have_content 'Login with Discord'
    end

    it 'logs in with discord after clicking Login with Discord' do
      OmniAuth.config.test_mode = true

      visit '/'

      click_on 'Login with Discord'

      expect(page).to_not have_content 'Login with Discord'

      find('.profile-menu').hover

      expect(page).to have_content 'Account Settings'
      expect(page).to have_content 'Event Calendar'
      expect(page).to have_content 'Logout'
    end
  end

  context 'when logged in' do
    context 'as an average user' do
      before do
        @user = build(:user, confirmed_at: Time.now)
        create(:profile, user: @user)

        login_as(@user, scope: :user)
      end

      it 'shows profile menu' do
        visit '/'

        find('.profile-menu').hover

        expect(page).to have_content 'Account Settings'
        expect(page).to have_content 'Event Calendar'
        expect(page).to have_content 'Logout'
      end

      it 'logs user out after pressing Logout' do
        visit '/'

        find('.profile-menu').hover
        find('.logout').click

        expect(page).to have_content 'Login with Discord'
      end

      it 'redirects to Events page after pressing Event Calendar' do
        event = create(:event)

        visit '/'

        find('.profile-menu').hover
        find('.event-calendar').click

        expect(page).to have_content event.title
      end

      it 'redirects to Account Settings page after pressing Account Settings' do
        visit '/'

        find('.profile-menu').hover
        find('.settings').click

        expect(page).to have_content 'Account Settings'
      end
    end

    context 'as an organiser' do
      before do
        @user = build(:user, confirmed_at: Time.now, role: :organiser)
        create(:profile, user: @user)

        login_as(@user, scope: :user)
      end

      it 'shows profile menu with Organiser Dashboard link' do
        visit '/'

        find('.profile-menu').hover

        expect(page).to have_content 'Organiser Dashboard'
      end

      it 'redirects to Organiser Dashboard page after pressing Organiser Dashboard' do
        visit '/'

        find('.profile-menu').hover
        find('.organiser-dashboard').click

        expect(page).to have_content 'Create Event'
      end
    end
  end
end

设计配置

require 'devise'

RSpec.configure do |config|
  config.include Warden::Test::Helpers
end

Javascript 驱动菜单重定向

handleCommand(command) {
  if (command === "logout") {
    Rails.ajax({
      url: "/sign_out",
      type: "DELETE",
      dataType: "json",
      success: (signed_in_status) => {
        this.$store.commit('authenticate', false)
        this.$message.success('You logged out');
        location.href = "/";
      },
      error: (signed_in_status) => {
        this.$store.commit('authenticate', true)
        this.$message.error('Something went wrong');
      }
    })
  }
  else if (command === "settings") {
    location.href = "/users/edit";
  }
  else if (command === "events") {
    location.href = "/events";
  }
  else if (command === "organiser") {
    location.href = "/admin/events";
  }
}

我似乎已经解决了这个问题。我已经尝试了这个 SO 答案中提到的几件事。据我所知，修复它的是什么修复了我的配置:

 RSpec.configure do |config|
   config.include Warden::Test::Helpers
 end

到

 RSpec.configure do |config|
   config.include Devise::Test::IntegrationHelpers, type: :system
 end

这也让我放弃了:

  after(:each) do
    Warden.test_reset!
  end

在我所有的测试中。我已经运行了很多测试，它们不再失败，所以我现在假设这个问题确实已经修复。
