How to parameterize junit Test Suite

Question

Is it possible to parameterize a TestSuite in junit 4 ?

For declaring a class as a test suite I need the annotation @RunWith(Suite.class), but the same

Answer 1

I was able to parameterize a test suite and use its data in a test class member of the suite as follows:

In JUTsuite:

@RunWith(Suite.class)
@Suite.SuiteClasses({ 
    JUT_test1.class,
})

public class JUTSuite{  
    // Declare all variables/objects you want to share with the test classes, e.g.
    protected static List<Fx> globalFxs;
    // This is the data list we'll use as parameters
    protected static List<Dx> globalDxs;

    @Parameters
    public static Collection<Object[]> data(){
        // Instantiate object list for parameters.  
        // Note: you must do it here and not in, say, @BeforeClass setup()
        // e.g.
        globalDxs=new ArrayList<Dx>(serverObj.values());

        Collection<Object[]> rows=new ArrayList<Object[]>();
        for(Dx d:globalDxs) {
            rows.add(new Object[]{d});
        }
        return rows;
    }

    @BeforeClass
    public static void setUp() throws Exception {
        // Instantiate/initialize all suite variables/objects to be shares with test classes
        // e.g. globalFxs=new ArrayList<Fx>();
    }

    @AfterClass
    public static void tearDown() throws Exception {
        // Clean up....
    }
}

Next, in test class:

@RunWith(Parameterized.class)
public class JUT_test1 {
    // declare local names (if desired) for suite-wide variable/objects 
    // e.g. 
    private static List<Fx> globalFxs;

    // This is the test parameter:      
    private Dx d;

    public JUT_test1(Dx d){
        this.d=d;
    }

    @Parameters
    public static Collection<Object[]> data(){
    // Note: we're calling the suite's data() method which has already executed.
        return JUTSuite.data();
    }

    @BeforeClass
    public static void setUpBeforeClass() throws Exception {
    // (If desired)initialize local variables by referencing suite variables.
    // e.g.globalFxs=JUTSuite.globalFxs;
    }
}
