> Perhaps you can use the encoder and manually change the last bitwidths in
the output?
Sure, it's easy to write that in my personal develop enviroment. But I
cannot submit these "mock" code to the codebase, which make writing unit test a
bit more trickey.
In my local machine, I can just use
```
for (uint32_t i = num_miniblocks; i < mini_blocks_per_block_; i++) {
- bit_width_data[i] = 0;
+ // bit_width_data[i] = 0;
+ bit_width_data[i] = static_cast<uint8_t>(random());
}
```
and run roundtrip tests. But in unit test, I should submit a test file or a
string. And I cannot test too much cases, because I need to paste the whole
string here.
By the way, do you think using Hex to represent binary is ok? And if not ok,
is there some good example?
