问题

在Github的CI上运行时，尝试访问页面时出现SocketError: getaddrinfo: Name or service not kNown。

     2.1) Failure/Error: visit '/'

          SocketError:
            getaddrinfo: Name or service not kNown

使用rspec和selenium_google_chrome_headless或selenium_google_chrome都可以在我的本地环境上正确运行测试。

应用

  • 这是一个多域应用程序，因此我的测试使用
before { Capybara.app_host = "http://#{subdomain}.myapp.test" }
  • 库版本
    • 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)
  • 这是我的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/[email protected]
      - 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

解决方法

使用 :headless_chrome 作为 javascript 浏览器，在 spec/spec_helper.rb 中有 this 配置

,

添加

Capybara.server = :puma

到我的spec/rails_helper.rb文件似乎可以解决我的主要问题。

我的测试仍然没有通过Github Action，但是看起来是另一个问题。
