How can I merge two different Allure results beloging to two different stages in a Jenkins Declarative Pipeline

Question

I have a Jenkins Declarative Pipeline with 2 different test stages both are configured to generate allure-results

I would like to merge these two allure-reports into a single allure-report and present it to the user in the Jenkins Pipeline workspace...

pipeline {
    agent none

    stages {
        stage('Sanity') {
            agent { label 'sanity-node' }
            steps {
                sh 'pytest -m sanity'
                stash name: 'sanity-results', includes: 'allure-results/**'
            }
        }
        stage('Regression') {
            agent { label 'regression-node' }
            steps {
                sh 'pytest -m regression'
                stash name: 'regression-results', includes: 'allure-results/**'
            }
        }
    }

    post {
        always {
            node('master') {

                dir('merged-allure-results') {
                    unstash 'sanity-results'
                    unstash 'regression-results'
                }

                allure([
                    includeProperties: false,
                    jdk: '',
                    properties: [],
                    reportBuildPolicy: 'ALWAYS',
                    results: [[path: 'merged-allure-results']]
                ])
            }
        }
    }
}

But some reason it doesn't seem to work! What am I doing wrong here? How can I achieve the desired outcome?

Answer 1

Allure does not know about the nested directories, so you need to pass both as results. Something like this:

    post {
        always {
            node('master') {

                dir('merged-allure-results') {
                    unstash 'sanity-results'
                    unstash 'regression-results'
                }

                allure([
                    includeProperties: false,
                    jdk: '',
                    properties: [],
                    reportBuildPolicy: 'ALWAYS',
                    results: [
                        [path: 'merged-allure-results'],
                        [path: 'regression-results']
                    ]
                ])
            }
        }
    }

Also, I would double check if those stashes are unstashed into different directories. I don't remember the structure of the results, but I doubt they could be safely merged just by copying everything in one place.
