| /** |
| * Tests the factories in SchedulingStrategy. |
| * <br> |
| * Th point of these tests is to check {@link Task#result} if changed |
| * from {@code false} to {@code true} after all scheduled tasks |
| * have finished. |
| * The call {@link SchedulingStrategy#finished()} is waiting until the |
| * strategy has finished. |
| * Then {@link Task#result} should be asserted that is {@code true}. |
