Operations tests
The different kinds of operations ("transactions") are tested individually with test handlers.
Test case format
meta.yaml
description: string -- Optional description of test case, purely for debugging purposes.
Tests should use the directory name of the test case as identifier, not the description.
bls_setting: int -- see general test-format spec.
pre.ssz_snappy
An SSZ-snappy encoded BeaconState, the state before applying the operation.
<input-name>.ssz_snappy
An SSZ-snappy encoded operation object, e.g. a ProposerSlashing, or Deposit.
post.ssz_snappy
An SSZ-snappy encoded BeaconState, the state after applying the operation. No value if operation processing is aborted.
Condition
A handler of the operations test-runner should process these cases,
calling the corresponding processing implementation.
This excludes the other parts of the block-transition.
Operations:
operation-name |
operation-object |
input name |
processing call |
|---|---|---|---|
attestation |
Attestation |
attestation |
process_attestation(state, attestation) |
attester_slashing |
AttesterSlashing |
attester_slashing |
process_attester_slashing(state, attester_slashing) |
block_header |
BeaconBlock |
block |
process_block_header(state, block) |
deposit |
Deposit |
deposit |
process_deposit(state, deposit) |
proposer_slashing |
ProposerSlashing |
proposer_slashing |
process_proposer_slashing(state, proposer_slashing) |
voluntary_exit |
SignedVoluntaryExit |
voluntary_exit |
process_voluntary_exit(state, voluntary_exit) |
sync_aggregate |
SyncAggregate |
sync_aggregate |
process_sync_committee(state, sync_aggregate) (new in Altair) |
execution_payload |
ExecutionPayload |
execution_payload |
process_execution_payload(state, execution_payload) (new in Merge) |
Note that block_header is not strictly an operation (and is a full Block), but processed in the same manner, and hence included here.
The execution_payload processing normally requires a verify_execution_state_transition(execution_payload),
a responsibility of an (external) execution engine.
During testing this execution is mocked, an execution.yml is provided instead:
a dict containing an execution_valid boolean field with the verification result.
The resulting state should match the expected post state, or if the post state is left blank,
the handler should reject the input operation as invalid.
