The following like is supposed to test that the two buffers have the same values but since they are not arrays the method doesn't test anything:

assert_array_equals(event_value, read_value);

We should change this to:

let read_value_arr = Array.from(new Uint8Array(read_value));
let event_values_arr = event_values.map(v => Array.from(new Uint8Array(v));

assert_array_equals(read_value_arr, event_values_arr);
