Consumers Guide

A Simple Example

Imagine that you want to publish a check with some details of a Jenkins build.

You need to first construct a ChecksDetails object:

ChecksDetails details = new ChecksDetailsBuilder()
        .withName("Jenkins CI")
        .withStatus(ChecksStatus.COMPLETED)
        .withConclusion(ChecksConclusion.SUCCESS)
        .withDetailsURL(DisplayURLProvider.get().getRunURL(run))
        .withCompletedAt(LocalDateTime.now(ZoneOffset.UTC))
        .build();

Then you can create a publisher based on a Jenkins Run to publish the check you just constructed:

ChecksPublisher publisher = ChecksPublisher.fromRun(run);
publisher.publish(details);

The publisher returned is based on the implementations you installed on your Jenkins instance.

Checks Parameters

The checks are highly customized by consumers due to a number of optional parameters provided.

Consumers can set these parameters through the checks models:

  • ChecksDetails: the top-level model of a check, including all other models and some basic parameters like status and conclusion
  • ChecksOutput: the output of a check, providing some displayed details like title, summary, URL, and code annotations
  • ChecksAnnotation: a code annotation of a check, providing a specific comment for one or multiple lines of code;
  • ChecksImage: an image of a check, providing an intuitive graph for the build like issues trend, coverage chart, must be a public URL that SCM platforms can fetch from
  • ChecksAction: an action of a check, providing further actions to be performed by users, like rerun a Jenkins build

Checks Publishers

The publishers are created through the static factory method (fromRun or fromJob) of ChecksPublisherFactory. The factory will iterate all available implementations of the ChecksPublisher in order to find the suitable publisher for the Jenkins Run or Job.

Pipeline Step: withChecks

The withChecks step injects a ChecksInfo object into its closure by users:

withChecks('MyCheck') {
  junit '*.xml'
}

The injected object can be resolved by other plugin developers in their Step implementation:

getContext().get(ChecksInfo.class)

Currently, the ChecksInfo object only includes a name specified by users, it is recommended that you look for this name and set it over your default checks name

Integration Testing

An implementation of ChecksPublisher that captures all published ChecksDetails is provided in the test classifier, as io.jenkins.plugins.checks.util.CapturingChecksPublisher.

Adding the factory for this publisher as a TestExtension will allow inspection of published checks after running a job on a JenkinsRule.

An example of this can be found in PublishChecksStepITest.
