Finality tests

The aim of the tests for the finality rules.

  • finality: transitions triggered by one or more blocks.

Test case format

meta.yaml

description: string    -- Optional. Description of test case, purely for debugging purposes.
bls_setting: int       -- see general test-format spec.
blocks_count: int      -- the number of blocks processed in this test.

pre.ssz_snappy

A SSZ-snappy encoded BeaconState, the state before running the block transitions.

Also available as pre.ssz_snappy.

blocks_<index>.yaml

A series of files, with <index> in range [0, blocks_count). Blocks need to be processed in order, following the main transition function (i.e. process slot and epoch transitions in between blocks as normal)

Each file is a YAML-encoded SignedBeaconBlock.

Each block is also available as blocks_<index>.ssz_snappy

post.ssz_snappy

A SSZ-snappy encoded BeaconState, the state after applying the block transitions.

Condition

The resulting state should match the expected post state, or if the post state is left blank, the handler should reject the series of blocks as invalid.
