# FSP Test Map
|
||
|
|
|
||
|
|
## Operator Tests
|
||
|
|
|
||
|
|
- Historical output schema, dtype, units, and source timestamp alignment.
|
||
|
|
- Realtime update equivalence with the final row of a batch recomputation.
|
||
|
|
- Warm-up, NaN, zero, gap, duplicate, and out-of-order behavior.
|
||
|
|
- Session reset and elapsed-time behavior.
|
||
|
|
- Parameter and source identity isolation.
|
||
|
|
|
||
|
|
## Engine Tests
|
||
|
|
|
||
|
|
- Equal absolute source/destination bounds.
|
||
|
|
- Normal one-step destination lag.
|
||
|
|
- Destination lead and lag greater than one step.
|
||
|
|
- Source prepend by one, two, and a full provider frame.
|
||
|
|
- In-place gap repair with unchanged source bounds.
|
||
|
|
- Equal lengths with shifted absolute bounds.
|
||
|
|
- Source change during historical recomputation and convergence afterward.
|
||
|
|
- Cancellation while the quote stream, sample stream, or compute generator is
|
||
|
|
blocked.
|
||
|
|
- Foreign FQME and timeframe backfill broadcasts.
|
||
|
|
|
||
|
|
## Graph and Actor Tests
|
||
|
|
|
||
|
|
- Dependency startup before downstream operator lookup.
|
||
|
|
- Actor-local flow registry isolation.
|
||
|
|
- One destination writer and multiple readers.
|
||
|
|
- Consumer cancellation without orphaned cascade or worker tasks.
|
||
|
|
- Worker failure propagation and SHM cleanup.
|
||
|
|
- Feed-like fan-out with a slow or disconnected consumer.
|
||
|
|
|
||
|
|
## UI Tests
|
||
|
|
|
||
|
|
- An `fsp_update` redraws every field visualization sharing its destination
|
||
|
|
token and no unrelated market, OHLC, or FSP visualization.
|
||
|
|
- A prepend outside the visible range does not move or re-range the live view.
|
||
|
|
- A revised value inside the visible range invalidates only required formatter
|
||
|
|
and graphics caches.
|
||
|
|
- Hidden charts defer rendering without stopping compute correctness.
|
||
|
|
|
||
|
|
## Performance Tests
|
||
|
|
|
||
|
|
- Historical bootstrap across realistic SHM capacities.
|
||
|
|
- O(1) realtime recurrence cost under bursty quotes.
|
||
|
|
- Consecutive provider-frame prepends with two or more cascades.
|
||
|
|
- Multi-market sampler broadcasts and targeted wakeups.
|
||
|
|
- Visible-range redraw cost at several units-per-pixel levels.
|
||
|
|
|
||
|
|
Prefer deterministic local arrays and controlled Trio task interleavings.
|
||
|
|
Use live providers only as a separate integration layer because credentials,
|
||
|
|
rate limits, sessions, and changing history make poor regression oracles.
