Scripted Pipeline

 node {
 
     echo 'Pipeline logic starts'
 
     stage('Build') {
        // ...
     }
     stage('Test') {
        // ...
     }
     stage('Deploy') {
        // ...
     }

Parallel Stages

stage("tests") {

    parallel(

        "unit tests": {

             // run unit tests 
         },
         "coverage tests": {

             // run coverage tests
         }
     )
}

Declarative Pipeline

 pipeline { 
     agent any 
     options {
         skipStagesAfterUnstable()
     }
     stages {
         stage('Build') { 
             steps { 
                 sh 'make' 
             }
         }
         stage('Test'){
             steps {
                 sh 'make check'
                 junit 'reports/**/*.xml' 
             }
         }
         stage('Deploy') {
             steps {
                 sh 'make publish'
             }
         }
     }
 }
