Maven/TestNG/Selenium - Can I set up multiple tests suites in one testng.xml and run different ones at different times?

Question

I am using Maven/TestNG/Selenium. I have about 50 tests in one suite and one file right now what I want to do is separate tests into several suites:

Acceptance - Will have the five tests to accept the build Full Pass - The other forty-five tests Debug - The one testing I am currently coding and debugging

I want to be able to run a particular suite as needed. Can I do this from one testng.xml file or do I need multiple files?

I think my testng.xml file will look something like:

 <suite name="ACCEPT">
  <test name="blah">   </test>
  <test name="foo">   </test>
</suite> 

<suite name="FULLPASS">
  <test name="T1">    </test>
 <test name="T2">    </test>
 <test name="T3">    </test>
</suite>

Answer 1

1. You can refer other suites in suite.xml as shown here
2. If you're using surefire you can configure execution in POM using suiteXmlFiles tag or by passing system property -Dsurefire.suiteXmlFiles=suite.xml like shown here
