Jenkins pipeline with pytest and allure

Use pipeline to better manage Jenkins job:

 pipeline {
   agent {
	  label 'jenkins_master'
	}
   
    parameters {
	  string defaultValue: '/tests/', description: 'Set test suite', name: 'TestSuite', trim: true
	  choice choices: ['qa', 'dev', 'product'], description: 'Set test run env', name: 'Environment'
	  string defaultValue: '', description: 'Set tag to run', name: 'Tag', trim: true
	  string defaultValue: '2', description: 'Set rerun times when failed', name: 'Rerun', trim: true
	  string defaultValue: '1', description: 'Set multiple thread to run', name: 'Parallel', trim: true
	}

   stages {
      stage('Get Automaiton Code') {
          steps{
            git credentialsId: 'xxxxxxx', url: 'https://xxx/api_automation.git'
          }
      }
	  
	  stage('Run Automation') {
          steps{
            sh label: '', script: '''if [ ! $Tag ]; then             pytest -s -v ${WORKSPACE}${TestSuite} --reruns ${Rerun} -n ${Parallel} --alluredir=./report/json --clean-alluredir            else             pytest -s -v ${WORKSPACE}${TestSuite} -m ${Tag} --reruns ${Rerun} -n ${Parallel} --alluredir=./report/json --clean-alluredir            fi'''

             pytest -s -v ${WORKSPACE}${TestSuite} --reruns ${Rerun} -n ${Parallel} --alluredir=./report/json --clean-alluredir

            else

             pytest -s -v ${WORKSPACE}${TestSuite} -m ${Tag} --reruns ${Rerun} -n ${Parallel} --alluredir=./report/json --clean-alluredir

            fi'''
          }
          }
	  
	}

    post('Allure Report') {
            always{
                script{
                    allure includeProperties: false, jdk: '', report: 'report/html/', results: [[path: 'report/json']]
