title: maven: How can I skip test in some projects via command line options?
body: <p>In my maven project I have a number of modules. Is it possible to turn off running unit test for some modules via command line options? </p>
  
  <p>My project takes about 15 mins to run through all unit tests. I would like to speed up the overall build by running just the unit tests in the module I am working on. I do not want to go in and edit each individual pom.xml to achieve this.</p>
  
  <p>I have tried a solution outlined here: <a href="https://stackoverflow.com/questions/2922581/can-i-run-a-specific-testng-test-group-via-maven">Can I run a specific testng test group via maven?</a> However the result is a lot of test failures in modules that I want to skip. I suppose 'group' is not the same concept of module?</p>
