JUnit Parameterized Tests - IllegalArgumentException: wrong number of arguments

I'm developing a Java Spring project. I have little experience with JUnit, and encountered this problem when creating parameterized tests.

I'm making a sample test of the method ReportTableOperations.addDurations() which is basically a SUM of two long values.

@RunWith(Parameterized.class)
public class ReportTableOperationsTest {

    @Parameters
    public static Collection<Object[]> data() {
      return Arrays.asList(new Object[][] {
          {3600L, 3600L, 7200L},
          {2000L, 3600L, 5600L}
      });
    }

    private long value1, value2, expected;

    public void AddDurationsTest(long value1, long value2, long expected) {
        this.value1 = value1;
        this.value2 = value2;
        this.expected = expected;
    }


    @Test
    public void testAddDurations() throws Exception {

        assertThat(ReportTableOperations.addDurations(value1, value2), is(expected));

    } 

 }

But I'm encountering the following errors when executing the test:

**java.lang.IllegalArgumentException: wrong number of arguments**

Anyone has any ideas in what could be causing this?
