Epoch processing tests

The different epoch sub-transitions are tested individually with test handlers. The format is similar to block-processing state-transition tests. There is no "change" factor however, the transitions are pure functions with just the pre-state as input. Hence, the format is shared between each test-handler. (See test condition documentation on how to run the tests.)

Test case format

description: string    -- description of test case, purely for debugging purposes
bls_setting: int       -- see general test-format spec.
pre: BeaconState       -- state before running the sub-transition
post: BeaconState      -- state after applying the epoch sub-transition.

Condition

A handler of the epoch_processing test-runner should process these cases, calling the corresponding processing implementation (same name, prefixed with process_). This excludes the other parts of the epoch-transition. The provided pre-state is already transitioned to just before the specific sub-transition of focus of the handler.

Sub-transitions:

• justification_and_finalization
• crosslinks
• rewards_and_penalties - planned testing extension
• registry_updates
• slashings
• final_updates

The resulting state should match the expected post state.
