Test format: Compute cells

Compute the cells for a given blob.

Test case format

The test data is declared in a data.yaml file:

input:
  blob: Blob -- the data blob
output: List[Cell] -- the cells

• Blob is a 131072-byte hexadecimal string, prefixed with 0x.
• Cell is a 2048-byte hexadecimal string, prefixed with 0x.

All byte(s) fields are encoded as strings, hexadecimal encoding, prefixed with 0x.

Condition

The compute_cells handler should compute the cells (chunks of an extended blob) for blob, and the result should match the expected output. If the blob is invalid (e.g. incorrect length or one of the 32-byte blocks does not represent a BLS field element) it should error, i.e. the output should be null.
