Create a selenium backend in a jenkins pipeline

There is 1 approach which is not via Kubernetes.

Use the below image in which nodejs and chrome both are installed.

  agent {    kubernetes {      defaultContainer 'jnlp'      yaml """        apiVersion: v1        kind: Pod        spec:            containers:              - name: node-chrome                image: larcado/nodejs-chrome                command:                - cat                tty: true      """    }  }  stages {    stage('Checkout codebase') {      // do checkout      }      }    stage('Build') {      steps {        container('node') {            sh '''                npm install --production            '''        }      }    }    stage('Test-Mocha') {      steps {        container('node') {            sh "node_modules/.bin/wdio ./test/config/wdio.conf.js --spec ./test/helpers/sandBox/sandbox1.js"        }      }    }  }}

Make sure as part of package.json, selenium-webdriver is part of it.

There are a couple of ways to do it.

1. Using Selenium Grid (Ideal way) - Below are the steps:

• Host a separate selenium Grid using the below docker-compose file.

version: '2'services:  firefox:    image: selenium/node-firefox:3.14.0-gallium    volumes:      - /dev/shm:/dev/shm    depends_on:      - hub    environment:      HUB_HOST: hub  chrome:    image: selenium/node-chrome:3.14.0-gallium    volumes:      - /dev/shm:/dev/shm    depends_on:      - hub    environment:      HUB_HOST: hub  hub:    image: selenium/hub:3.14.0-gallium    ports:      - "4444:4444"

• Execute the docker-compose up -d command to start the Selenium Grid which is running localhost:4444

• Once this grid is running, please generate the wdio config which be used to run against a grid.

  Ref: https://webdriver.io/docs/clioptions.html

• After config is generated, run your pipeline by using the pipeline which you mentioned in your question, which will run against the Selenium Grid

Note:- Use the new wdio config which you generated to use against the selenium grid.

Hope this helps.
