Jacoco, Spring Boot, Maven and Junit 5, JaCoCo Jenkins Plugin

This project runs JUnit tests under code coverage and creates a coverage report (target/site/jacoco/index.html).

run:

mvn clean verify

Also this project excludes MainApplication.class to show how excludes/includes works (https://www.jacoco.org/jacoco/trunk/doc/report-mojo.html#excludes).

If you want, comment or remove <configuration> <excludes> under <plugins>section in the pom.xml and you will still have 100% code coverage because contextLoads() @Test is implemented. But keep in mind that there are scenarios where you don't want this behavior. Instead, @Test void contextLoads(){...} can be part of integration Tests.

I am going to show you how to use the JaCoCo Jenkins Plugin to achieve the same goal of jacoco-maven-plugin and have overall code coverage statistics for all modules.

The first step is installing the JaCoCo Jenkins plugin

Go to Jenkins -> Manage Jenkins -> Manage Plugins -> Available(tab) and find JaCoCo plugin

• notice that you need to have JaCoCo Maven plugin in your pom.xml, like this project.

Add Post-build Actions to the job responsible for packaging the application. -> Record JaCoCo coverage report.

for simplicity you can use this project.

Install and configure Jenkins if you had not done so before.

For this example, I use a maven project. If you don't have Maven Project option. This link can help you: https://stackoverflow.com/questions/45205024/maven-project-option-is-not-showing-in-jenkins-under-new-item-section-latest

Also you need to configure Jenkins -> Global Tool Configuration: JDK, Maven (Add Maven)
