How yo get test execution report after JUnitCore.runClasses

I have following code to start my class methods in parallel:

@Test
public void test() throws Exception {
    Class[] cls = {OrderPlacementCancelTest.class};
    Result result = JUnitCore.runClasses(new ParallelComputer(false, true), cls);
}

I understand that runClasses returns Result but I don't understand how can I get test run report. looks like Result can it.
