| The general strategy of these tests (for interface levels 1 and 2) is |
| to create a dummy FLAC file with a known set of initial metadata |
| blocks, then keep a mirror locally of what we expect the metadata to be |
| after each operation. Then testing becomes a simple matter of running |
| a FLAC__FileDecoder over the dummy file after each operation, comparing |
| the decoded metadata to what's in our local copy. If there are any |
| differences in the metadata, or the actual audio data is corrupted, we |
| will catch it while decoding. |
