CI/CD Jenkins setup with docker image for Cucumber (BDD) projects.

 

Jenkins ( cloudbees ) set up for running BDD script from git hub

  1. Create a maven project for BDD push the script in git hub.

Jenkinsfile.

def network='jenkins-${BUILD_NUMBER}' def seleniumHub='selenium-hub-${BUILD_NUMBER}' def chrome='chrome-${BUILD_NUMBER}' def firefox='firefox-${BUILD_NUMBER}' def containertest='conatinertest-${BUILD_NUMBER}'   def MODL='cucumber.api.cli.Main --glue "StepDefinitions" classpath:Features' pipeline {           agent {                 any {                     image 'maven:3-alpine'                     args '-v $HOME/.m2:/root/.m2'                 }             }      stages{       stage('Setting Up Selenium Grid') {          steps{                      sh "docker run -d -P -p 4444:4444 --name ${seleniumHub} selenium/hub"                 sh  "docker run -d -P  -p 5900:5900 --link ${seleniumHub}:hub  --name ${chrome} selenium/node-chrome-    debug:3.141.59-yttrium"             }       }        stage('Build Jar') {             steps {                 sh 'mvn clean package -DskipTests'             }         }         stage('Build Image') {             steps {                 script {                   app = docker.build("vagrant/containertest")                   sh "pwd"                 }             }         }       stage('Run Test') {          steps{                             sh "docker run --rm -e SELENIUM_HUB=${seleniumHub} -e BROWSER=chrome  -v ${WORKSPACE}/target:/usr/share/suman/ vagrant/containertest"                   archiveArtifacts artifacts: 'target/**', fingerprint: true          }       }       stage('Tearing Down Selenium Grid') {           steps {              //remove all the containers and volumes              sh "docker rm -vf ${chrome}"         sh "docker rm -vf ${seleniumHub}"                        }         }      } }

 DockerFile

FROM openjdk:8-jre-slim   WORKDIR /usr/share/suman   ADD /target/container-test-tests.jar container-test.jar ADD  /target/libs libs   ADD pom.xml pom.xml ENV BROWSER = chrome ENV POMM  = AutomationPipeline ENV SELENIUM_HUB = http://192.168.3.12:4444/wd/hub   ENTRYPOINT java -cp container-test.jar:libs/* -DseleniumHubHost=$SELENIUM_HUB -Dbrowser=$BROWSER cucumber.api.cli.Main --glue "StepDefinitions" classpath:Features /usr/share/suman/

2. Now set up Jenkins ( CloudBess ) for the execution and pull the script from git hub

3. Git, Jenkins, maven, Java8, docker should be cloud machine

4. Create a jenkins pipeline

   

6. We can see the running execution on through the VNC viewer

 Now Open VNC Viewer and put the port shown on terminal: Usually it   will be 5900: so put localhost:5900 on the VNC browser.
