# Operations tests
|
|
|
|
|
|
|
|
|
|
The different kinds of operations ("transactions") are tested individually with test handlers.

## Test case format

### `meta.yaml`

|
|

```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`

|
|
|
|
2021-03-13 04:42:51 +00:00
|
|
|
An SSZ-snappy encoded `BeaconState`, the state before applying the operation.
|

|
|

|
2020-10-08 19:02:18 +00:00

### `<input-name>.ssz_snappy`

|
|
|
|
2021-03-13 04:42:51 +00:00
|
|
|
An SSZ-snappy encoded operation object, e.g. a `ProposerSlashing`, or `Deposit`.

|
|
|
|
2021-03-13 04:42:51 +00:00
|
|
|
An SSZ-snappy encoded `BeaconState`, the state after applying the operation. No value if operation processing is aborted.

## Condition
|
|
|
|
|
|
2019-06-10 20:16:51 +00:00
|
|
|
A handler of the `operations` test-runner should process these cases,
|
2019-05-23 09:22:10 +00:00
|
|
|
calling the corresponding processing implementation.
|
2019-06-30 12:35:07 +00:00
|
|
|
This excludes the other parts of the block-transition.

Operations:

|

| `sync_aggregate` | `SyncAggregate` | `sync_aggregate` | `process_sync_aggregate(state, sync_aggregate)` (new in Altair) |

| `execution_payload` | `ExecutionPayload` | `execution_payload` | `process_execution_payload(state, execution_payload)` (new in Bellatrix) |

|
|
|
|
2019-06-10 20:20:45 +00:00
|
|
|
Note that `block_header` is not strictly an operation (and is a full `Block`), but processed in the same manner, and hence included here.
|
2019-05-23 09:22:10 +00:00
|
|
|
|
2021-05-04 22:37:00 +00:00
|
|
|
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.
|
|
|
|
|
|
2019-05-23 09:22:10 +00:00
|
|
|
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.
