How to use the pydriller.domain.modification.ModificationType.ADD function in PyDriller

def test_should_get_adds_and_removes():

    diff = "+++ diff info\n" \
       + "+ new line\n" \
       + "- removed line\n" \
       + "+ new line\n" \
       + "\n" \
       + "+ new line\n" \
       + "- removed line\n" \
       + "+++ more git stuff\n" \
       + "--- more git stuff\n"

    m = Modification("old", "new", ModificationType.ADD, diff, "class Java {} ");

    assert 3 == m.added
    assert 2 == m.removed
