To run a single test method in Maven, you require to provide the command as:
mvn test -Dtest=TestCircle#xyz test
Here TestCircle is the test class name and xyz is the test method.
Wild card figures also work; both in the method name and class name.
If you're inquiring in a multi-module project, define the module that the test is in with -pl <module-name>.
For integration tests you can try it.test=... option instead of test=...:
mvn -pl <module-name> -Dit.test=TestCircle#xyz integration-test
