# 问题 1: Isar Core 动态库下载失败
IsarError: Could not download IsarCore library:
Stack Trace:
  package:isar_community/src/native/isar_core.dart 154:5  _downloadIsarCore

# 问题 2: 变量未初始化错误
LateInitializationError: Local 'isar' has not been initialized.
When the exception was thrown, this was the stack:
#0      LateError._throwLocalNotInitialized (dart:_internal-patch/internal_patch.dart:215:5)
#1      main.<anonymous closure>.<anonymous closure> (test/features/settings/conflict_resolution_screen_test.dart)

# 问题 3: Widget 测试 HTTP 拦截警告
Warning: At least one test in this suite creates an HttpClient. When running a test suite that uses
TestWidgetsFlutterBinding, all HTTP requests will return status code 400, and no network request
will actually be made.

# 问题 4: 选择器组件超时
Exception: Timed out waiting for finder to disappear: Found 1 widget with type "LocationSelector": [...]
#0      WidgetTesterExtensions.pumpUntilGone (test/helpers/widget_test_helper.dart:177:5)

Isar 库下载冲突 & Widget 测试 400 异常
  ├─ TestWidgetsFlutterBinding 自动 Mock 并断网
  │   └─ 解决：在 python 启动前静默串行跑 Unit 测试，把动态库预先下载到根目录
  ├─ setUp 里的 runAsync 静默吞掉异常，误报 late 初始化错误
  │   └─ 解决：移除 runAsync，使底层错误直接断开 setup 抛出
  └─ 选择器组件在并发 CPU 负载下频频超时
      ├─ 解决 1：将 tap 目标由 Icon 精确指向外层 IconButton 容器
      └─ 解决 2：将 pumpUntilGone 的极限超时拉伸至 20 秒
