I was very excited to know about the ‘parallel’ feature in Jenkins Pipeline, but, there are many gotchas while making  use of the pipeline feature (many of which are documented here: Jenkins Pipeline Example). After trying and reading a few different solutions, following worked for me (notice in screenshot that the browser jobs run in parallel !)

pipeline {
  agent any
  stages {
    stage('Build') {
      steps {
        echo 'hello'
      }
    }
    stage('Test') {
      steps {
        script {
            def jobs = [:]
            def browsers = ["Chrome", "Firefox"]
            for (int i = 0; i < browsers.size(); i++) {
                def browser = browsers.get(i)
                def jobName = "printing $browser"
                jobs[jobName] = doJob(browser)
            }
            parallel jobs
        }
      }
    }
    stage('Deploy') {
      steps {
        echo 'deploying'
      }
    }
  }
}

def doJob(browser) {
    return {
        node {
            echo "testing in $browser"
        }
    }
}
