How to fix "Test reports were found but none of them are new. Did tests run?" in Jenkins - email

Question

I am getting the error "Test reports were found but none of them are new. Did tests run?" when trying to send unit test results by email. The reason is that I have a dedicated Jenkins job that imports the artifacts from a test job to itself, and sends the test results by email. The reason why I am doing this is because I don't want Jenkins to send all the developers email during the night :) so I am "post-poning" the email sending since Jenkins itself does not support delayed email notifications (sadly).
However, by the time the "send test results by email" job executes, the tests are hours old and I get the error as specified in the question title. Any ideas on how to get around this problem?

Answer 1

You could try updating the timestamps of the test reports as a build step ("Execute shell script"). E.g.
cd path/to/test/reports
touch *.xml

Answer 2

mvn clean test
via terminal or jenkins. This generates new tests reports.
The other answer that says cd path/to/test/reports touch *.xml didn't work for me, but mvn clean test yes.

Answer 3

Updating the last modified date can also be achieved in gradle itself is desired:
task jenkinsTest{
inputs.files test.outputs.files
doLast{
def timestamp = System.currentTimeMillis()
test.testResultsDir.eachFile { it.lastModified = timestamp }
}
}
build.dependsOn(jenkinsTest)

Here's an updated version for Jenkinsfile (Declarative Pipeline):
pipeline {
agent any
stages {
stage('Build') {
steps {
sh 'make build'
}
}
stage('Test') {
steps {
sh 'make test'
script {
def testResults = findFiles(glob: 'build/reports/**/*.xml')
for(xml in testResults) {
touch xml.getPath()
}
}
}
}
}
post {
always {
archiveArtifacts artifacts: 'build/libs/**/*.jar', fingerprint: true
junit 'build/reports/**/*.xml'
}
}
}

Answer 5

Because gradle caches results from previous builds I ran into the same problem.
I fixed it by adding this line to my publish stage:
sh 'find . -name "TEST-*.xml" -exec touch {} \\;'
So my file is like this:
....
stage('Unit Tests') {
sh './gradlew test'
}
stage('Publish Results') {
// Fool Jenkins into thinking the tests results are new
sh 'find . -name "TEST-*.xml" -exec touch {} \\;'
junit '**/build/test-results/test/TEST-*.xml'
}

Answer 6

Had same issue for jobs running repeatedly (every 30 mins).
For the job, go to Configure, Build, Advanced and within the Switches section add:
--stacktrace
--continue
--rerun-tasks

Answer 7

This worked for me
Navigate to report directory cd /report_directory
Delete all older report rm *.xml
Add junit report_directory/*.xml in pipeline
Rerun the test script , navigate to Build Number → Test Result
Make sure you have one successful build without any failure, only after this you can able to see the reports

Answer 8

Make sure that you have mentioned the correct path against "Test report XMLs" under jenkins configuration, such as "target/surefire-reports/*.xml"
There is no need to touch *.xml as jenkins won't complain even though test results xml file does not change.

Answer 9

if you use Windows slave, you can 'touch' results using groovy pipeline stage with powershell:
powershell 'ls "junitreports\\*.*" | foreach-object { $_.LastWriteTime = Get-Date }'

Answer 10

It happens if you are using a test report which is not modified by that job in that run.
In case for test purpose if you are testing with already created file then, add below command inside jenkins job under Build > Execute Shell
chmod -R 775 /root/.jenkins/workspace/JmeterTest/output.xml
echo " " >> /root/.jenkins/workspace/JmeterTest/output.xml
Above command changes timestamp of file hence error wont display.
Note: To achieve same in Execute Shell instead of above, do not try renaming file using move mv command etc. it won't work , append and delete same for change file timestamp only works.

Answer 11

For me commands like chmod -R 775 test-results.xml or touch test-results.xml does not work due to permission error. As work around use is to set new file in test report settings and command to copy old xml report file to new file.

Answer 12

you can add following shell command to your "Pre Steps" section when configure your job on Jenkins
mvn clean test
this will clean the test

Answer 13

Here's an updated version of the gradle task that touch each test result files.
From Jenkins pipeline script, just call "testAndTouchTestResult" task instead of "test" task.
The code below is with Kotlin syntax:
tasks {
register("testAndTouchTestResult") {
setGroup("verification")
setDescription("touch Test Results for Jenkins")
inputs.files(test.get().outputs)
doLast {
val timestamp = System.currentTimeMillis()
fileTree(test.get().reports.junitXml.destination).forEach { f ->
f.setLastModified(timestamp)
}
}
}
}

Answer 14

The solution for me was delete node_modules and change node version (from 7.1 to 8.4) on jenkins. That's it.
