Debugging tests and integration tests

Note: mvnDebug command works properly in Maven 3.5.0+

Debug usual tests (ends with Test word)

mvn -Dmaven.surefire.debug test
Tests run by maven-surefire-plugin and use 5005 port by default

mvnDebug -DforkCount=0 test
Tests run by maven-surefire-plugin and use 8000 port by default

Debug using non-default remote port

mvn -Dmaven.surefire.debug="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000 -Xnoagent -Djava.compiler=NONE" test

Debug one particular test class:

mvn -Dmaven.surefire.debug test -Dtest=SomeTest

Debug one particular test method

mvn -Dmaven.surefire.debug test -Dtest=SomeTest#someMethod

Debug integration tests

mvn -Dmaven.failsafe.debug verify

Tests run by maven-failsafe-plugin and use 5005 port

Without particular configuration failsafe plugin consider that integration tests are all tests which have IT in name

Debug using non-default remote port

mvn -Dmaven.failsafe.debug="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000 -Xnoagent -Djava.compiler=NONE" verify

Debug one particular test class

mvn -Dmaven.failsafe.debug verify -Dit.test=SomeIT

Debug one particular test method

mvn -Dmaven.failsafe.debug verify -Dit.test=SomeIT#someMethod
