Jenkins - JaCoCo Integration

                        

Code Coverage is an important measurement used during development that describes the degree to which source code is tested. Jacoco is a code coverage library for java, which is created by EclEmma team,

In this article , we will see how to configure Jacoco with Jenkins.  We will configure the integration and we will run a maven build which will generate the test reports.

1.  Install the Jacoco plugin using the Jenkins Plugin manager

2. There is nothing to configure from the Jenkins side on the Jacoco integration.

3. Create a Maven Job and configure the Github repo with the test code written.

4. Select the “Record JaCoCo Coverage Report” from the Post build action.

5. Configure the Jacoco Coverage report with the below details,

  

Provide the path for the exec files, inclusions and exclusions. Also we need to pass the path for the source code where they are. Some example are provided in the above image.

6. Run the build and once success we will see the below coverage report. A link will be created on the left side of the job for accessing the details.
