Code Coverage - Usage

To use the Code Coverage plug-in, the plug-in must be loaded, and an instance created. Load the plug-in into the IBM DevOps Velocity container if necessary.

Integration steps

1. In IBM DevOps Velocity, click Settings > Integrations > Available.
2. In the Action column for the Code Coverage plug-in, click Install.
3. The plug-in is now listed in the Installed tab and available for invoking.

Integration type

The Code Coverage plug-in is a parser type plug-in and it parses data from the following test tools:

• LCOV
• Cobertura
• JaCoCo
• Clover

Invoking the plug-in

You can invoke the plug-in manually using a REST Call or by using a Jenkins plug-in to integrate IBM DevOps Velocity in a Jenkins environment.

Invoke using Jenkins plug-in

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

Example

pipeline {
agent any
stages {
stage('codeCoverageMetrics') {

steps {
step([$class: 'UploadMetricsFile',  appName: 'My Code-Coverage Test', dataFormat:
'cobertura', filePath: '<location of the code coverage report>', name: 'my-code_coverage-test', pluginType:
'coverageData', tenantId: '<tenant Id>', testSetName: 'code_coverage', metricsRecordUrl: "``${env.BUILD_URL}``"])

}``
}``
}``
}``

Invoke the plug-in using a Rest call

When using a REST call to invoke the Code Coverage 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_devopsvelocity_server>/reporting-consumer/metrics
BODY
(multipart/form-data):
{
payload: <json_object_string> // See below for schema format
testArtifact:
<cobertura/etc_xml_file>
}``

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
"metricName":
"<metric_name>", // optional: name for recurring test set
"application": {
"name": "<application_name>"  //Name
of application
}``,
"record": {
"recordName": "<record_name>", // optional: Name for this record

"executionDate": 1547983466015, // optional: UNIX Epoch
"pluginType": "coverageData",
"dataFormat":
"cobertura",       // cobertura, lcov, jacoco
"metricsRecordUrl": "<Jenkins_build_url>" // optional: To link the
Jenkins build with test results
}``,
"build": {  // Optional: One of the following fields must be included

"buildId": "<build_id>",
"jobExternalId": "<external_job_id>",
"url": "<build_url>",
}``,
"commitId":
"<commit_id>",  // optional
"pullRequestId": "<pullrequest_id>", // optional
"environment": "<environment_name>"
// optional
}``

Example using Curl

curl --request POST \
--url https:///reporting-
consumer/metrics \
--form 'payload={
"tenant_id": "*tenant\_id*",
"application": {
"name": "My
Application"
}``,
"record": {
"pluginType": "coverageData",
"dataFormat": "cobertura"
}``
}``
' \

--form testArtifact=@test-result/junit.xml
