Introduces a per-route fixture-override hook on fakespeaker.Config so
open issues with concrete device-side payloads can become repeatable
regression tests, then demonstrates the pattern by wiring issue #218.
Foundation. Config grows a single optional field:
FixtureOverrides map[string][]byte
Routes named in the map (e.g. "/presets", "/sources", "/info") return
the supplied bytes; routes not in the map fall through to the embedded
testdata defaults the screenshot pipeline relies on. Stateful handlers
(/getGroup, /addGroup, /updateGroup, /removeGroup) are unaffected
because they're code-driven, not fixture-driven. The override slice is
snapshotted at construction so later mutations of the caller's slice
don't change the served body. Zero-value Config keeps the existing
behaviour, so cmd/dummy-speaker + scripts/screenshots are untouched.
Iteration zero — issue #218.
pkg/service/setup/issue218_regression_test.go starts a fakespeaker
serving the reporter's LOCAL_INTERNET_RADIO preset XML verbatim (URL:
content.api.bose.io/core02/svc-bmx-adapter-orion/prod/orion/station?…),
runs Manager.syncPresets against it, then asserts the persisted
Presets.xml retains the Bose cloud URL prefix. This locks in the
"location preserved through sync" contract; when AfterTouch starts
rewriting the URL to its own base (the eventual fix for #218), the
assertion flips and the fixture stays unchanged — the test is the
carrier for the decision.
Pattern reference for future issue regression tests: this exemplar
mirrors pkg/service/marge/recents_sourceproviderid_regression_test.go's
style (issue link, trigger chain in the doc-comment, locked-in
assertion) but is the first one to drive the device side via fakespeaker
rather than an inline httptest.NewServer. Subsequent issues with
device-side payloads (#234 factory-reset state, #235 Spotify-as-preset,
…) can reuse the FixtureOverrides hook without further infrastructure.
