> `git diff HEAD~1..HEAD -- piker/brokers/replay.py`
|
||
|
|
|
||
|
|
Implements a fixture-driven market-data backend with typed scenario,
|
||
|
|
quote, failure, command, acknowledgement, snapshot, and transcript
|
||
|
|
structures. It provides the normal market-info, bounded history,
|
||
|
|
quote-stream, search, and Tractor control endpoints without external
|
||
|
|
network access.
|
||
|
|
|
||
|
|
> `git diff HEAD~1..HEAD -- tests/_inputs/replay/ tests/replay/test_contract.py`
|
||
|
|
|
||
|
|
Adds versioned basic and failure scenarios plus focused validation and
|
||
|
|
history-boundary tests. The scenarios carry normalized market metadata,
|
||
|
|
one-second and one-minute OHLCV arrays, sequenced quotes, and a named
|
||
|
|
failure point.
|
||
|
|
|
||
|
|
## Verification
|
||
|
|
|
||
|
|
- Python compilation, Ruff, JSON parsing, and staged whitespace checks
|
||
|
|
pass.
|
||
|
|
- Scenario normalization and bounded repeatable history tests pass.
|
||
|
|
- The production history contract exposed a need for Pendulum datetime
|
||
|
|
values; the implementation was corrected before final verification.

## Design discussion
|
||
|
|
|
||
|
|
The user questioned placing test infrastructure beside production
|
||
|
|
backends and proposed dynamic test registration. The resulting review
|
||
|
|
identified standard Python package entry points as the preferred future
|
||
|
|
mechanism for external and testing backends. The user then deprioritized
|
||
|
|
replay entirely in favor of real-backend chart E2E and requested that
|
||
|
|
the completed experiment be parked with that follow-up recorded.
