### Question:
ChunkHash implements Comparable<ChunkHash> { public byte[] getHash() { return mHash; } ChunkHash(byte[] hash); byte[] getHash(); @Override boolean equals(Object o); @Override int hashCode(); @Override int compareTo(ChunkHash other); @Override String toString(); static final int HASH_LENGTH_BYTES; }### Answer:
@Test public void testGetHash_returnsHash() { ChunkHash chunkHash = new ChunkHash(TEST_HASH_1); byte[] hash = chunkHash.getHash(); assertThat(hash).asList().containsExactlyElementsIn(Bytes.asList(TEST_HASH_1)).inOrder(); }
