From 8be22b3f310b84bf49242b25120fac105e8b0597 Mon Sep 17 00:00:00 2001 From: Young Liu Date: Fri, 9 Jan 2026 00:11:26 +0800 Subject: [PATCH 1/3] Add UI and ViewModel tests; update docs and coverage Added ArithmeticUITests.swift for comprehensive UI testing and GameViewModelTests.swift for detailed ViewModel logic tests. Updated TESTING_INSTRUCTIONS.md and TEST_COVERAGE_SUMMARY.md to reflect new test organization and coverage. Improved documentation in CLAUDE.md and reorganized license and testing sections in README.md. Added placeholders in UtilsTests.swift to indicate test suite migration. --- CLAUDE.md | 3 +- README.md | 10 +- TESTING_INSTRUCTIONS.md | 117 ++++++++++--------- TEST_COVERAGE_SUMMARY.md | 200 ++++++++++---------------------- Tests/ArithmeticUITests.swift | 198 ++++++++++++++++++++++++++++++++ Tests/GameViewModelTests.swift | 201 +++++++++++++++++++++++++++++++++ Tests/UtilsTests.swift | 23 +++- 7 files changed, 548 insertions(+), 204 deletions(-) create mode 100644 Tests/ArithmeticUITests.swift create mode 100644 Tests/GameViewModelTests.swift diff --git a/CLAUDE.md b/CLAUDE.md index de7f56f..1ff9155 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -40,9 +40,10 @@ xcodebuild -project Arithmetic.xcodeproj -scheme Arithmetic build -verbose ### Localization Checks ```bash -# Check consistency between Chinese and English localization files +# Check consistency between Chinese and English localization files and embed Git info ./scripts/check_localizations.sh ``` +**Note**: This script validates that both `en.lproj` and `zh-Hans.lproj` contain identical keys, and also embeds Git commit information into the app bundle. ### Code Review Use the **swift-code-reviewer agent** after writing or modifying Swift code.
