I am trying to understand what is going on with “Multibranch Pipeline” in jenkins, and I have found an example here: https://www.geeksforgeeks.org/build-test-and-deploy-a-flask-rest-api-application-from-github-using-jenkins-pipeline-running-on-docker/
So I was trying to create a new case myself by using that git example. But somehow, it fails in the “test” session.
here is the copy of the “Jenkinsfile” in that example,
pipeline {
agent any
stages {
stage('Build') {
parallel {
stage('Build') {
steps {
sh 'echo "building the repo"'
}
}
}
}
stage('Test') {
steps {
sh 'python3 test_app.py'
sh 'echo ${params.project_name}'
input(id: "Deploy Gate", message: "Deploy ${params.project_name}?", ok: 'Deploy')
}
}
stage('Deploy')
{
steps {
echo "deploying the application"
sh "sudo nohup python3 app.py > log.txt 2>&1 &"
}
}
}
post {
always {
echo 'The pipeline completed'
junit allowEmptyResults: true, testResults:'**/test_reports/*.xml'
}
success {
echo "Flask Application Up and running!!"
}
failure {
echo 'Build stage failed'
error('Stopping early…')
}
}
}
And I am using Jenkins of version 2.387.3.
Here is the picture of my job execution, 
and in the test log, I have seen such message:
...
The pipeline completed
[Pipeline] junit
Recording test results
[Checks API] No suitable checks publisher found.
[Pipeline] echo
Build stage failed
[Pipeline] error
Error when executing failure post condition:
