Can I run only one method in a testcase?

Test case example as follows (mytest.js):

exports["test1f"] = function(test){
test.expect(1);
test.ok(true, "this assertion should pass");
test.done();
};

exports["test2"] = function(test){
test.ok(true, "this assertion should pass");
test.done();
};

I hope that I can run test2 only like this:

nodeunit test.js test2
