# @ahoo-wang/wow-client/testing symbol index

Every name `@ahoo-wang/wow-client/testing` exports — 8 — with its kind and the first sentence of its TSDoc, generated from the built declarations. 0 of them are described by hand in the curated pages, linked in the last column; the rest are read from their source through the signature in the [API report](https://github.com/Ahoo-Wang/Wow/blob/main/typescript/wow-client/test/api/testing.api.md). This index is English only.

| Symbol | Kind | Summary | Covered in |
|---|---|---|---|
| `DevelopmentCaller` | interface | Who a request comes from, as a development run of a Wow service reads it (`DevelopmentCallerHeaders`). | — |
| `DevelopmentCallerHeaders` | const | The identity headers a development run of a Wow service reads the caller from (the host's development callers, in a profile of `wow.dev-profiles`, when CoSec is off): any client can set them, so a deployment never reads them. | — |
| `commandResultOf` | function | A command's result as a service answers it, for a test's fake: the command`ref` names, committed (`succeeded` at `committed`, version 1) unless`overrides` says otherwise. | — |
| `developmentCaller` | function | A request interceptor that sends every request as `caller`, by the headers a development run reads (`developmentCallerHeaders`): a fetcher that uses it asks as that caller, as a host's CoSec interceptors send its token. | — |
| `developmentCallerHeaders` | function | The headers that name `caller` to a development run: only those it sets. | — |
| `problemOf` | function | An RFC 9457 problem as a service answers it, of `status` and the Wow `code` (`urn:wow:error:<code>`; `about:blank` without one), for a test's fake or an expected error. | — |
| `problemResponse` | function | The response a service answers `problem` with: `application/problem+json`, its extension members written as members of their own, as the wire carries them. | — |
| `snapshotOf` | function | An aggregate's snapshot as a state read and a snapshot query answer it, for a test's fake: `ref`'s `state` at version 1, committed at 0 by an anonymous caller, of no owner or space, not deleted, untagged and keeping no schedules unless `overrides` says otherwise. | — |
