How to run nodeJS tests with Jenkins

Question

I am learning about Jenkins CI and using pipeline to stage my jobs. I've ran into a halt where my tests aren't running. Please take a look at my "Jenkins Images" link. As you can see its stuck in the --coverage table. Typically, if i were to run my tests on my local machine, i would have to enter wcommand to get node to run all tests; however, i don't think it would be the same in a jenkins setting

        choice(name: 'VERSION', choices: ['1.1.0', '1.2.0', '1.3.0'], description: '')
        booleanParam(name: 'executeTests', defaultValue: true, description: '')

            steps {
                script {
                   gv = load "script.groovy"
                   CODE_CHANGES = gv.getGitChanges()
                }
            }
        }
        stage("build frontend") {
            steps {
                dir("client") {
                    sh 'npm install'
                    echo 'building client'
                }
            }

            steps {

                        env.BRANCH_NAME.toString().equals('feature-jenkins') && CODE_CHANGES == false
                    }
                }
