JUnit testing with multiple test cases in a method

I have a following class A with a constructor that takes two strings as parameters.

Class A
{
String test1;
String test2;

    public(String test1, String test2)
    {
    this.test1 = test1;
    this.test2 = test2;
    }
}

I would like to test a constructor with three test cases within a one test case method i.e. 1. Null test1 2. Null test2 3. Null test1, Null test2

String test1 = "ABC";
String test2 = "XYZ";
@Test(expected=NullPointerException.class)
public void testNullConstructorValues() {
       new A(null, test2);
       new A(test1, null);
       new A(null, null);
}

The problem here is that after first constructor declaration, the method throws NPE and returns out of the method. I would like the method to execute all 3 constructor declarations within just one method and perform the expected exception check.

Is there any way to do this of doing all 3 test cases within one method?
