Answer 1

I didn't test with TestNG 5.12.1 but I can say that running a single test using the test parameter and tests from groups using the groups parameter works with TestNG 5.14.2 (and surefire 2.6) (groups doesn't work in TestNG 5.14)

Here is the pom.xml I'm using:

  4.0.0

      5.14.2
      test
    
  
  
    
      
        org.apache.maven.plugins
        maven-surefire-plugin
        2.6
        
      
    
  

With a simple AppTest as follow:

import org.testng.annotations.*;

public class AppTest {

 @BeforeClass
 public void setUp() {
   // code that will be invoked when this test is instantiated
 }

 @Test(groups = { "fast" })
 public void aFastTest() {
   System.out.println("Fast test");
 }

 @Test(groups = { "slow" })
 public void aSlowTest() {
    System.out.println("Slow test");
 }

}

Both

$ mvn test -Dtest=AppTest

and

$ mvn test -Dgroups=slow

produce the expected result.
