Running test from different modules using a testng suite in maven multi module project?

Question

I want to run unit test present in different modules of my maven project from a testng suite that contains specific test classes. One method that i have tried is to make another module and add dependencies of the different modules that i require test from as a test-jar but this method requires me to add all the dependencies that the modules i have added for test dependencies.

project is structure like

Project 
|
|- Module A
   |- src
   |- suitefiles
   |- pom.xml
|- Module B
   |- src
   |- suitefiles
   |- pom.xml
|-pom.xml(Parent pom)

I have tried to add a third module like

Project 
|
|- Module A
   |- src
   |- suitefiles
   |- pom.xml
|- Module B
   |- src
   |- suitefiles
   |- pom.xml
|- Module C
   |- src
   |- suitefiles
   |- pom.xml <-(A and B as dependencies here)
|-pom.xml(Parent pom)

I want to omit making a separate module every time to run combine test from 2 modules. Is there a simpler way?

Answer 1

This should run tests for modules A and B both.

mvn test -pl A,B
