Cloud Automation Setup

Complete setup to run UI Automation in cloud.

To run web automation suites in the Jenkins, we need to ensure that the following items are preinstalled in the Linux & Jenkins server.

1. Need to have Lanugage specific requirements or specific docker images.
2. Need to have the required browsers in which automation suites are going to run. (eg., Chrome, Firefox, etc.,)
3. Need to have (Selenium) Drivers corresponding to the browsers. (When Selenium 4.0+ is released this drivers is need not to be installed separately, since it will have internal driver manager.)
4. Each Jenkins slave (where UI automation is running) should have minimum 2GB ram and minimum 2 core processor with 1.2GHZ processor.
5. Allure plugin to be added in Jenkins (For reporting purpose)

      }
    }
    stage('build') {
      steps {
        sh 'bundle install'
      }

      }
    }
    stage('build') {
      steps {
