How to pass java code a parameter from maven for testing

Question

I need to pass on following values …

exeEvironment (Test environment) , testGroup (Group in testNG)

from Command-Line ->

Answer 1

You need not define anything for groups in testng xml or the pom, the support comes inbuilt. You can simply specify the groups on the cmd line http://maven.apache.org/plugins/maven-surefire-plugin/test-mojo.html#groups

Hope it helps..

Edit 2:

Ok..so here's another option...Implement IMethodInterceptor

Define your custom property. Use -Dcustomproperty=groupthatneedstoberun in your command line call.

In the intercept call, scan through all methods ..something to the effect..

System.getProperty("customproperty");
for(IMethodInstance ins : methods) {
    if(ins.getMethod().getGroups()) contains group)
        Add to returnedVal;
    }
return returnedVal;

Add this to the listeners list in your xml.
