27 tests across 4 files, all targeting code that was already testable
the moment the target existed -- no visibility bumps, no refactors:
- GitignoreParserTests: MCPService.GitignoreParser's glob-to-regex
matching (wildcards, **, directory anchors, negation, comments).
- OpenRouterModelsTests: the string-vs-content-block-array decoders
on both the request side (APIMessage.MessageContent/ContentItem)
and response side (Choice.MessageContent, StreamChoice.Delta),
including image extraction from content blocks.
- AIProviderTests: ChatResponse/Usage decoding, with an explicit
regression guard that Usage.rawCostUSD always decodes to nil (it's
only ever set programmatically, never from API JSON).
- MessageCodableTests: confirms Message's transient fields
(isStreaming, isStarred, generatedImages, toolCalls,
thinkingContent) don't survive an encode/decode round-trip, and
documents that its custom == deliberately ignores role/timestamp/
attachments/modelId -- a real but non-obvious behavior worth
locking in with a test.
Removed the placeholder oAITests.swift example test now that there's
real coverage. Phase 1 of the test-suite rollout plan
(peaceful-baking-kurzweil).
