🧪 [完善 AppResult 单元测试] by 01luyicheng · Pull Request #183 · 01luyicheng/NetProxyGateway

01luyicheng · 2026-07-31T09:57:08Z

🎯 What: 为 AppResult 及其所有的扩展函数添加了完整的单元测试，填补了测试空白。
📊 Coverage: 覆盖了所有的基础状态方法 (isSuccess, isError, getOrNull, exceptionOrNull)，伴生对象方法 (success, error, fromResult, runCatching) 以及所有的扩展函数 (onSuccess, onError, map, mapError, flatMap, getOrDefault, getOrElse, getOrThrow, toResult, recover, recoverCatching, filter, zip) 的成功和失败分支。
✨ Result: 显著提高了 AppResult 类的测试覆盖率，确保了基础结果类型在各种场景下的稳定性和可靠性。

11-260: 测试命名建议已在先前审查中提出。

先前审查建议测试命名采用仓库惯例，例如 map_success_transformsValue，以替代当前的 testXxx 风格。此建议属于非阻断优化，已记录在案，此处不重复展开。

99-108: map/flatMap 异常传播测试缺失，已在先前审查中提出。

testMap（第 99-108 行）和 testFlatMap（第 125-138 行）未覆盖 transform 函数内部抛出异常时的传播行为。先前审查已建议补充此类测试，此处标记为重复，不再重复要求。

Also applies to: 125-138

13-97: LGTM!

PR Summary by Qodo

Add comprehensive unit tests for AppResult and its extensions

🧪 Tests 🕐 20-40 Minutes

AI Description

• Add a full JUnit test suite covering AppResult success/error states.
• Verify companion factories and Kotlin Result interop (fromResult/runCatching/toResult).
• Cover all extension functions across success and failure branches (map/zip/recover/etc.).

High-Level Assessment

The following are alternative approaches to this PR:

1. Use parameterized tests / table-driven cases

➕ Reduces duplication across success/error branch assertions
➕ Makes it easier to add new extension-function cases consistently
➖ Slightly higher setup complexity in JUnit4
➖ Can reduce readability for very small, single-purpose tests

2. Adopt Kotest (property/data-driven testing)

➕ Cleaner DSL for data-driven and property-based assertions
➕ Can validate algebraic/monadic laws for map/flatMap/zip more thoroughly
➖ Introduces/expands test dependencies and conventions
➖ Migration cost if the codebase is standardized on JUnit

Recommendation: Current approach (explicit JUnit tests per API) is appropriate for quickly establishing coverage without new dependencies. If these tests grow further, consider refactoring repeated patterns into table-driven/parameterized tests to keep maintenance cost low.

Add full unit test coverage for AppResult and extension functions

• Introduces JUnit tests for AppResult core state helpers (isSuccess/isError/getOrNull/exceptionOrNull), companion factories (success/error/fromResult/runCatching), and all extension functions (onSuccess/onError/map/mapError/flatMap/getOr*/toResult/recover*/filter/zip). Each API is exercised for both success and failure branches, validating value propagation and exception handling.

独立复核结论：APPROVE（带 nit）。测试正确、覆盖全、能编译。

已核实：新增 AppResultTest.kt 共 17 个 @Test，覆盖 AppResult 全部公共 API 的成功与失败分支：success/error/fromResult/runCatching、onSuccess/onError、map/mapError/flatMap、getOrDefault/getOrElse/getOrThrow、toResult/recover/recoverCatching、filter/zip。逐方法核对：所有引用的方法/签名均存在于 AppResult.kt，测试能编译。filter(predicate, errorProvider) 的 filter({ it > 5 }) { Exception(...) } 调用合法；zip 第一错误优先（error1.zip(error2) → "error1"）断言正确；recoverCatching 把 transform 包进 runCatching 故抛异常变 error，断言正确；getOrThrow 错误态抛出原异常，用 try/catch+fail 验证。成功/失败双分支均覆盖；onSuccess/onError 用 var called 验证回调触发与短路。无定时/并发，不会 flaky。

nit（非阻断）：

命名用 testSuccessState/testMap/testZip 这类泛化 testX，不符合本仓 方法_条件_预期 惯例（参见 IpAddressUtilsTest 的 validateIpv4WithResult_rejectsEmptyString、VpnDnsConfigTest 的 resolveDnsServers_..._when...）。建议对齐，如 map_success_transformsValue、zip_bothErrors_keepsFirstError。
可选补 map/flatMap transform 抛异常时的传播用例（生产代码不 catch，会向上抛）。

只读复核，未修改任何文件。

01luyicheng · 2026-07-31T19:53:42Z

提交后审查（2026-08-01）

结论：纯测试新增（AppResultTest.kt，260 行），低风险。

检查要点

仅新增测试文件，不改动生产代码，无功能/安全影响。
建议确认覆盖：AppResult.success / .error 状态、isSuccess/isError 谓词、data/error 取值、equals/hashCode 契约（若 AppResult 是 data class）、以及空 data / 空 error 等边界。
若 CI（:app:testDebugUnitTest）通过即可合并。

如已覆盖上述场景，无其他问题。
