This is a sample script of installing and testing a Laravel application using Jenkins pipeline

pipeline-of-installing-and-testing-laravel-application

node {
    stage('download') {
        git branch: 'master', url: 'github/url/to/your/project'
    }
    stage('install') {
        sh 'composer install'
    }
    stage('init') {
    	sh 'cp .env.example .env'
    	sh 'php artisan key:generate'
    	sh "sed -i -e 's/DB_DATABASE=homestead/DB_DATABASE=staging/g' .env"
    	sh "sed -i -e 's/DB_USERNAME=homestead/DB_USERNAME=yourusername/g' .env"
    	sh "sed -i -e 's/DB_PASSWORD=secret/DB_PASSWORD=yourpassword/g' .env"
    }
    stage('integration_testing') {
    	sh 'vendor/bin/phpunit tests/Feature'
    }
    stage('acceptance_testing') {
    	// Because we'll use database as session driver during testing, we have to explictly migrate sessions table.
        sh 'php artisan migrate'
    	sh 'cp .env .env.dusk.local'
    	sh "sed -i -e 's;APP_URL=http://localhost;APP_URL=your.domain.com;g' .env.dusk.local"
    	// Use database as session driver instead of file so that every single test will not share the same session context.
    	sh "sed -i -e 's/SESSION_DRIVER=file/SESSION_DRIVER=database/g' .env.dusk.local"
    	// Allow web server to access storage directory.
    	sh 'sudo chmod -R 775 storage/'
    	sh 'sudo chown -R :www-data storage/'
    	sh 'php artisan dusk'
    }
}

does in this case Jenkins and Laravel live on the same server? coz i don't see the step for uploading the app.
