java - How do I get my Maven Integration tests to run

Question

I have a maven2 multi-module project and in each of my child modules I have JUnit tests that are named Test.java and Integration.java for unit tests and integration tests respectively. When I execute:

mvn test

all of the JUnit tests *Test.java within the child modules are executed. When I execute

mvn test -Dtest=**/*Integration

none of the Integration.java tests get execute within the child modules.

These seem like the exact same command to me but the one with the -Dtest=/*Integration** does not work it displays 0 tests being run at the parent level, which there are not any tests

Answer 1

The Maven build lifecycle now includes the "integration-test" phase for running integration tests, which are run separately from the unit tests run during the "test" phase. It runs after "package", so if you run "mvn verify", "mvn install", or "mvn deploy", integration tests will be run along the way.

By default, integration-test runs test classes named **/IT*.java, **/*IT.java, and **/*ITCase.java, but this can be configured.

For details on how to wire this all up, see the Failsafe plugin, the Failsafe usage page (not correctly linked from the previous page as I write this), and also check out this Sonatype blog post.
