This PR introduces test coverage for two previously untested utilities in OBAKitCore.
(Note: This branch builds on top of the Formatters and Theme PR, so you might see those commits here until the previous PR is merged).

What changed:

  • OBAKitTests/Utilities/LoggerTests.swift: Added tests for the shared Logger utility to verify that log statements are successfully recorded and retrieved from OSLogStore.
  • OBAKitTests/Utilities/ImageBadgeRendererTests.swift: Validated ImageBadgeRenderer size configurations and verified that drawImageOnRoundedRect outputs a UIImage matching the initialized badgeSize.

These tests ensure that diagnostic logging and foundational UI icon rendering behave predictably.

Summary by CodeRabbit

  • Tests
    • Added coverage for theme metrics and color initialization.
    • Added tests for image badge sizing, default behavior, and rendering output.
    • Added logging verification tests.
    • Expanded formatter tests for time, date, accessibility, and arrival/departure status handling.
    • Added broader validation for formatting consistency across common date, time, and status scenarios.

📝 Walkthrough

Walkthrough

Four Swift Testing suites add coverage for formatter output, theme constants and colors, image badge rendering, and asynchronous logger output retrieval. The formatter test file also contains encoding changes that affect comments and two ellipsis expectations.

Changes

Test coverage

Layer / File(s) Summary
Formatting and accessibility validation
OBAKitTests/Application/FormattersTests.swift
Adds tests for time formatting, contextual date and time output, and future, present, and past arrival or departure accessibility strings. Encoding changes affect comments and map-route overflow expectations.
Theme value validation
OBAKitTests/Theme/ThemeTests.swift
Adds assertions for theme metric constants and shared theme colors.
Utility behavior validation
OBAKitTests/Utilities/ImageBadgeRendererTests.swift, OBAKitTests/Utilities/LoggerTests.swift
Adds tests for image badge sizing and rendering. Adds a serialized logger test that polls combined log content for a logged message.

The test target cannot compile, and formatter tests will fail deterministically. These issues should be corrected before merge.

I've closed #1433 in favour of this one — your branch merged feature/formatters-tests in, so this PR is a strict superset of it and reviewing both meant reviewing the same diff twice. Everything from that PR carries over here.

The tests are in good shape. I checked all six ThemeMetrics values against Theme.swift, the four ThemeColors assertions against their literal assignments in init, and all eight VoiceOver strings against both the OBALoc defaults and the actual en.lproj entries — no drift in any of them. The Logger and ImageBadgeRenderer suites cover types that had nothing before.

Two things before this can land.

It needs a rebase. #1308 landed while this was open and rewrote the body of contextualDateTimeString, so Formatters.swift now conflicts. Nothing you did — just sequencing.

I'd like the public var now seam changed. This is the one substantive point. It adds permanent mutable public API to a white-label framework in a PR titled "add unit tests," and the PR body doesn't mention the production change at all. The codebase already has a convention for injecting a clock — private let dateProvider: () -> Date passed through init, in PushRegistrationManager — and Formatters takes every other environment dependency the same immutable way via init(locale:calendar:themeColors:).

What decides it for me is that the seam isn't buying anything. contextualDateTimeString has zero callers anywhere in the repo — a full-text search returns only its own definition — so it's dead public API, and the test that motivated the seam doesn't need it: under the original isDateInToday, contextualDateTimeString(Date()) is unconditionally the "today" branch. Please either take the date through init or drop the seam and let the test use Date().

A few smaller things, none blocking, take or leave them:

  • LoggerTests.swift:32 polls with up to 20 × 0.1s of Thread.sleep. The test target defaults to main-actor isolation and this suite isn't opted out, so on the failing path that blocks the main thread for ~2s while other main-actor suites are running concurrently. A polling loop with Task.sleep would avoid it.
  • ThemeTests's constant assertions mirror each static let back at itself, so they can only fail when someone deliberately edits a constant. We pruned similar assertions from this very file in 58e1d1d4.
  • Initialization sets properties correctly in ImageBadgeRendererTests asserts only badgeSize; fillColor and backgroundColor are private and unverified, so the name promises more than it delivers. Likewise Rendering produces a UIImage of expected size would pass against a blank image — the size is just the bounds handed to the renderer.
  • Both new files are missing a trailing newline. SwiftLint never sees them (included: covers only OBAKit, OBAKitCore, OBAWidget), so nothing catches it automatically.

Rebase and swap the seam and I'll turn this around quickly.

312-315: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Avoid the midnight boundary race.

If midnight occurs after line 312, contextualDateTimeString can return a date-and-time string while timeFormatter returns only the time. The test then fails intermittently. This repeats the prior review finding.

- Line 251: Restore the Unicode ellipsis in the map-route test expectations:
update the assertions at OBAKitTests/Application/FormattersTests.swift lines
251-251 and 265-265 to use \u{2026} instead of the mojibake text …, keeping
them consistent with the existing ellipsis containment check.

In `@OBAKitTests/Utilities/LoggerTests.swift`:
- Line 32: Update the Logger correctly writes and retrieves logs test
declaration to async throws, and replace the try? await Task.sleep call with try
await so the test compiles and propagates cancellation.
