# Measurement Test Evidence

Status: baseline suite created and executed.

## Required Test Layout
- `nodes/measurement/test/basic/*.test.js`
- `nodes/measurement/test/integration/*.test.js`
- `nodes/measurement/test/edge/*.test.js`
- `nodes/measurement/test/helpers/*.js`

## Test-to-Contract Mapping
| Test file | Scope | Primary contracts anchored |
|---|---|---|
| `nodes/measurement/test/basic/specific-constructor.basic.test.js` | constructor baseline and range derivation | `Measurement` constructor |
| `nodes/measurement/test/basic/scaling-and-output.basic.test.js` | scaling constraint and output update path | `calculateInput`, `updateOutputAbs`, `getOutput` |
| `nodes/measurement/test/basic/nodeclass-routing.basic.test.js` | topic routing and registration output shape | `nodeClass._attachInputHandler`, `_registerChild` |
| `nodes/measurement/test/integration/examples-flows.integration.test.js` | example package integrity and expected topic drivers | `nodes/measurement/examples/*.flow.json` |
| `nodes/measurement/test/integration/measurement-event.integration.test.js` | measurement container event emission contract | `updateOutputAbs`, measurement emitter wiring |
| `nodes/measurement/test/edge/invalid-payload.edge.test.js` | non-numeric input payload ignored behavior | `nodeClass._attachInputHandler` measurement branch |
| `nodes/measurement/test/edge/outlier-toggle.edge.test.js` | current outlier toggle behavior capture | `toggleOutlierDetection` |

## Executed
- Command:
  - `cd nodes/measurement && npm test`
- Result:
  - `pass: baseline suite` (see latest run in session)
- Date:
  - February 19, 2026

## Known Gaps Captured by Tests
- Outlier toggle currently converts config object to boolean.
- Measurement topic currently ignores numeric strings.
