Execute "Publish TestNG results" step in Jenkinsfile

Question

I'm trying to convert an existing set of Jenkins jobs to the new pipeline syntax, and I don't understand how to convert the post-build action "Publish TestNG results". The pipeline syntax page doesn't help as this specific action is not listed, so I've tried the following syntax:

step([$class: 'hudson.plugins.testng.Publisher', reportFilenamePattern: 'test-output/testng-results.xml'])

My assumption being that the class name would have to match the content of config.xml in the current configuration:

<hudson.plugins.testng.Publisher plugin="[email protected]">
  <reportFilenamePattern>test-output/testng-results.xml</reportFilenamePattern>
  <escapeTestDescp>true</escapeTestDescp>
  <escapeExceptionMsg>true</escapeExceptionMsg>
  <showFailedBuilds>false</showFailedBuilds>
  <unstableOnSkippedTests>false</unstableOnSkippedTests>
  <failureOnFailedTestConfig>false</failureOnFailedTestConfig>
</hudson.plugins.testng.Publisher>

However, an exception is being thrown when executing the statement :

So my questions are :

• is it possible to trigger any kind of post-job action using the 'step' statement ?
• if yes, is there a rule of thumb to find the class name, and attribute names ?

In case that's relevant for the question, I'm running Jenkins 2.8 with all pipeline plugins up to date, and the full Jenkinsfile can be found on GitHub

Answer 1

Publishing TestNG test results is now available in Pipelines. Use:

step([$class: 'Publisher'])

or with custom location of the result file:

step([$class: 'Publisher', reportFilenamePattern: '**/custom/testng-results.xml'])

According to this comment on Jenkins Jira adding to Pipeline snippet generator is pending.

(tested on Jenkins 2.9.13 and Pipeline plugin 2.4)

Answer 2

At this time, the TestNG Plugin isn't compatible with Pipelines. See JENKINS-27121
