I can find in the Maven docs where it shows how to run:
AFAIK there are no command line parameter for surefire:test to run tests in a specific package.
I use a configuration variable to achieve the same effect. A fragment of my pom.xml:
org.apache.maven.plugins
maven-surefire-plugin
2.7.2
**/${testGroup}/*Test.java
Now if I want to run tests in a package named "com.example", I use the following command:
mvn test -DtestGroup=com/example
