A Java/Maven/JUnit HelloWorld example

A „Hello World!” sample written in Java using Maven for the build, that showcases a few very simple tests.

This example demonstrates:

• A simple Java 8 application with tests
• Unit tests written with JUnit 5
• Integration tests written with JUnit 5
• Code coverage reports via JaCoCo
• A Maven build that puts it all together

Running the tests

• To run the unit tests, call mvn test
• To run the integration tests as well, call mvn verify
• Code coverage reports are generated when mvn verify (or a full mvn clean install) is called. Point a browser at the output in target/site/jacoco-both/index.html to see the report.

Conventions

This example follows the following basic conventions:

	unit test	integration test
resides in:	src/test/java/*Test.java	src/test/java/*IT.java
executes in Maven phase:	test	verify
handled by Maven plugin:	surefire	failsafe
