Property of [`testing.FakeSessionOptions`](testing.FakeSessionOptions.md) · stable · since 2.0.0

```ts
assets?: Readonly<Record<string, {
  load?: {
    ms?: number;
    fail?: boolean;
  };
}>>;
```

Images other than GLBs, keyed by URL as written, before `assetBaseUrl`: a [`TextureSpec`](TextureSpec.md)'s
`url` or `optimizedUrl`, a map slot's bare URL string (loaded exactly like `{ url }`), a
stored MaterialNode's map (loaded when [`select()`](Writer.select.md) or the scene model wears that node),
[`StageSettings.environment.url`](StageSettings.environment.md), a `background` panorama's `url`.
A URL with no entry decodes after [`decodeMs`](testing.FakeSessionOptions.decodeMs.md). An entry with `load.fail` fails as that URL's
fetch or decode would, `load.ms` after its request (as a [`models`](testing.FakeSessionOptions.models.md) entry's failure), once per
request: each slot that names it records its own
'asset-failed' (`url` as written, `asset` 'texture' or 'environment', and `op`): a stored
MaterialNode's map names that MaterialNode in `node`, a collection item's or a stage layer's
carries its `path`, and a rule, [`materials.create`](Materials.create.md) or [`apply`](Writer.apply.md) texture carries neither: match it
by `op`, as on the runtime. Spec section 6.4's texture row applies, its failure window included. A detail map whose
`load.ms` runs past its write's commit point lands, or fails, late without delaying the
colour maps (spec section 6.6, rule 7).

**Default:** {}

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `assets` names no product |
| 2. A precedent | not recorded: no ledger row (coverage.json) names this member or its owner |
| 3. Two apps, or labs | not recorded: no ledger row names this member or its owner |
| 4. The cheaper fix first | not recorded per member (Appendix B decides it per need) |
