I can find in the Maven docs where it shows how to run:
It may not be the best answer, but you could run a single TestSuite (which is a Test) which includes all the test you want in one package.
It can also be done by
mvn clean test -Dtest="**/service/**/*.java"
eg: I am in my /home/repository and I want to run tests on /home/repository/service folder only
Here service folder is inside my current folder.
Had the same problem (how to run all tests in a particular package) and tried many ways, two commands that worked were:
mvn -Dtest=com.package.my.package.** test
mvn -Dtest=com.package.my.package.**.* test
