JUnit - Usage

To use the JUnit plug-in, the plug-in must be loaded and an instance created. Load the plug-in into the IBM DevOps Velocity container if necessary. From the user interface, click Settings > Integrations > Plugins. On the Plug-ins page, locate the plug-in and click Load Plugin. To create an instance, locate the plug-in and click Install. The plug-in is now listed below those plug-ins to be installed and available for invoking.

Integration type

The JUnit plug-in is a parser type plug-in. It parses JUnit XML data.

Invoking the plugin

• To gather data from the Junit server, send an HTTP Post request with the data to parse. Whenever a there is a hit to the endpoint, the data is parsed and displayed as metrics in IBM DevOps Velocity. You can use various methods such as Postman, REST calls, CURL, and CI/CD tools like Jenkins to invoke the plug-in endpoints.

Invoke using Jenkins plugin

• Install the IBM DevOps Velocity plug-in into your Jenkins server. In your freestyle job or pipeline use the UCV-Upload Metrics File to UrbanCode Velocity step and provide the required fields. This step allows your build job to upload generated coverage results files to IBM DevOps Velocity.

pipeline {
   agent any
   stages {
      stage('junitMetrics') {
         steps {
            step([$class: 'UploadMetricsFile',  appName: 'My Junit Test', dataFormat: 'junitXML', filePath: '<location of the junit report>', name: 'my-junit-test', pluginType: 'junitXML', tenantId: '<tenant Id>', testSetName: 'junit', metricsRecordUrl: "${env.BUILD_URL}"])
         }
      }
   }
}

Invoke the plugin using a Rest call

When using a REST call to invoke the Junit plug-in, it must be a POST method and include the location of the IBM DevOps Velocity quality data endpoint.

The following request sample shows a REST call that you can copy and update as necessary. Key points about the snippet:

• The URL points to the IBM DevOps Velocity quality data endpoint. Update with the server location for your installation of IBM DevOps Velocity.

• The BODY of the call is a multipart/form data. It includes information about the payload.

METHOD: POST 
URL: https://<url_ibm_devops_velocity_server>/reporting-consumer/metrics 
BODY (multipart/form-data):
 {
  payload: <payload_json_object_string> // See below for schema format
 testArtifact: <junit_xml_file>
 }

Invoke using Curl

curl --request POST \
  --url https://url_ibm_devops_velocity_server>/reporting-consumer/metrics \
  --form 'payload={
  "tenant_id": "",
  "application": {
    "name": "My Application"
  },
  "record": {
    "pluginType": "junitXML",
    "dataFormat": "junitXML"
  }
}
' \
  --form testArtifact=@test-result/junit.xml

Payload schema

The following shows the schema for the payload. Replace the angle brackets with your values for the parameters.

{
  "tenant_id": "<tenant_id>",    // required Tenant ID

    "url": "<build_url>",
  },
  "commitId": "<commit_id>",  // optional
  "pullRequestId": "<pullrequest_id>", // optional
  "environment": "<environment_name>" // optional
}
