如何為 Rails + Rspec + Capybara & Selenium Webdrivers 設置 Github CI 用於多域應用程序？

Question

問題

在 Github 的 CI 上運行時，我得到一個SocketError: getaddrinfo: Name or service not known when trying to visit a page。

     2.1) Failure/Error: visit '/'

          SocketError:
            getaddrinfo: Name or service not known

使用rspec和selenium_google_chrome_headless或selenium_google_chrome在我的本地環境中正確運行測試。

該應用程序

• 這是一個多域應用程序，所以我的測試運行

before { Capybara.app_host = "http://#{subdomain}.myapp.test" }

• 庫版本
  • Ruby 2.5.5
  • gem 'rails', '~> 5.2.4'
  • gem 'rspec-rails', '~> 3.8'
  • capybara (3.33.0)
  • webdrivers (4.4.1)
    • selenium-webdriver (3.142.7)
• 這是我的 Github CI 工作流程

env:
  RUBY_VERSION: 2.5.5
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Start database
        run: |
          sudo systemctl start mysql
      - name: Set up Ruby 2.5.5
        run: |
          sudo apt-add-repository -y ppa:rael-gc/rvm
          sudo apt-get update
          sudo apt-get -y install rvm
          source /etc/profile.d/rvm.sh
          rvm install ${{ env.RUBY_VERSION }}
      - name: setup-chromedriver
        uses: nanasess/setup-chromedriver@v1.0.1
      - name: Build and test
        env:
          DATABASE_PASSWORD: root
        run: |
          source /etc/profile.d/rvm.sh
          rvm use ${{ env.RUBY_VERSION }}
          gem install bundler
          bundle install --jobs 4 --retry 3
          mysql -uroot -p${{ env.DATABASE_PASSWORD }} --execute="CREATE DATABASE myapp_test"
          RAILS_ENV=test rails db:setup
          bundle exec rspec spec/system

Answer 1

使用：headless_chrome 作為 javascript 瀏覽器，並在 spec/spec_helper.rb 中使用此配置

Answer 2

添加

Capybara.server = :puma

我的spec/rails_helper.rb文件似乎解決了我的主要問題。

我的測試仍然沒有通過 Github 操作，但它看起來是一個不同的問題。
