    Sum sum = new IntegerSum(0);
    // testing getBatchCount returns 1
    int numBatches = batchIterable.getBatchCount(100000);
    for (int i = 0; i < numBatches; ++i) {
        batchIterable.batchForEach(new SumProcedure<>(sum), i, numBatches);
    }
    Assert.assertEquals(1, numBatches);
    Assert.assertEquals(expectedValue, sum.getValue());
    // Testing 3 batches with chains and uneven last batch
    Sum sum2 = new IntegerSum(0);
    for (int i = 0; i < 5; ++i) {
        batchIterable.batchForEach(new SumProcedure<>(sum2), i, 5);
    }
    Assert.assertEquals(expectedValue, sum2.getValue());
}
