		38	+## 测试与验证
		39	+
		40	+本仓库包含两类自动化验证：
		41	+
		42	+1. 单元/集成测试与覆盖率（Mocha + c8）：
		43	+
		44	+ ```bash
		45	+ npm run test:coverage
		46	+ ```
		47	+
		48	+2. Cangjie 语言服务器（LSP）验证，用于确认语法高亮、跳转、悬停、补全等功能正常，需要本机已安装 Cangjie 插件并配置 `CJMP_SDK_HOME`：
		49	+
		50	+ ```bash
		51	+ export CJMP_SDK_HOME=/path/to/cjmp-sdk
		52	+ npm run test:lsp
		53	+ ```
		54	+
		55	+ 其中 `npm run test:lsp:protocol` 运行 `test/lsp-protocol/` 下的 mocha 套件，直接以 LSP 协议握手 LSPServer 并逐项断言响应；`npm run test:lsp:e2e` 由 `test/lsp-e2e/run-lsp-e2e.mjs` 在真实 VS Code 扩展宿主中加载 Cangjie 插件，运行 `test/lsp-e2e/` 下的端到端用例，通过 `vscode.executeDefinitionProvider` 等内置命令验证。
		56	+
		57	+ e2e 忠实复现真实用户环境：测试时把已安装的 Cangjie 插件原样复制进测试宿主，不做任何修补。测试的意义在于暴露真实问题，而非追求绿灯——在 Cangjie 插件 1.1.0 + CJMP SDK 0.6.2 下，server 支撑的跳转/悬停/语义高亮/补全会失败（已知缺陷，正是测试要暴露的）：插件 ① macOS/Linux 下只传 `CANGJIE_PATH` 不传 `CANGJIE_HOME`，server 无法定位标准库；② 总发无效 `stdLibPathOption`（SDK 不含 `lib/src`），致 server 语义结果全为 null。仅 TextMate 文法高亮可用。protocol 套件（直接握手原始 server 并正确传参）全绿，可证问题出在插件层而非 server 本身。
		58	+
		59	+ 其他环境变量：`CANGJIE_LSP_HOME`（直接指定 cangjie 工具链根目录）、`CANGJIE_VSCODE_EXTENSION_DIR`（指定 Cangjie 插件目录）、`CANGJIE_E2E_VSCODE_VERSION`（指定测试宿主 VS Code 版本，默认 1.130.0）。

	16	+/**
	17	+ * End-to-end verification of the Cangjie language server inside VS Code.
	18	+ *
	19	+ * The installed Cangjie extension is copied into the test host byte-faithful
	20	+ * (no patching), reproducing exactly what a user's VS Code does. The suite is
	21	+ * meant to EXPOSE real defects, not mask them: a red e2e is a real finding,
	22	+ * not a nuisance to paper over. The Mocha suite in test/lsp-e2e drives VS Code
	23	+ * built-in commands (vscode.executeDefinitionProvider, vscode.executeHoverProvider,
	24	+ * vscode.provideDocumentSemanticTokens, ...) against the fixture workspace and
	25	+ * asserts that syntax highlighting, go-to-definition, hover, etc. work.
	26	+ *
	27	+ * Prerequisites:
	28	+ * - The Cangjie extension installed for the current user
	29	+ * (~/.vscode/extensions/ide-innovation-lab.cangjie-*), or point
	30	+ * CANGJIE_VSCODE_EXTENSION_DIR at an unpacked extension directory.
	31	+ * - CJMP_SDK_HOME pointing at a CJMP SDK (the cangjie toolchain is resolved
	32	+ * as $CJMP_SDK_HOME/cjmp-tools/third_party/cangjie-android), or
	33	+ * CANGJIE_LSP_HOME pointing directly at the toolchain root.
	34	+ *
	35	+ * Known finding the suite is designed to surface (not hide):
	36	+ * With cangjie extension 1.1.0 + CJMP SDK 0.6.2 on macOS the server-backed
	37	+ * features (go-to-definition, hover, semantic tokens, document symbols,
	38	+ * completion) fail because the extension (1) spawns LSPServer without
	39	+ * passing CANGJIE_HOME, so the server cannot locate the standard library,
	40	+ * and (2) always sends an invalid stdLibPathOption pointing at a lib/src
	41	+ * that this SDK does not ship. Only the TextMate-grammar checks pass.
	42	+ * These are real extension/SDK defects; the protocol suite in
	43	+ * test/lsp-protocol confirms the raw server itself is healthy (it passes
	44	+ * when given a correct CANGJIE_HOME and no stdLibPathOption).
	45	+ *
	46	+ * Other knobs:
	47	+ * CANGJIE_E2E_VSCODE_VERSION — VS Code version for the test host
	48	+ * (default 1.130.0, verified working with @vscode/test-electron 3.1.0).
	49	+ * CANGJIE_E2E_TEST_GLOB — override the compiled test glob (debugging).

	20	+
	21	+\| # \| 用例 \| 测试内容 \| 关键实际返回 \| 结论 \|
	22	+\|---\|---\|---\|---\|---\|
	23	+\| 1 \| initialize server info \| 入口验证：握手确认对端为 Cangjie server \| `{"name":"Cangjie language server","version":"1.0"}` \| ✔ \|
	24	+\| 2 \| capabilities \| initialize 声明受验能力（definition/hover/highlight/semanticTokens/symbol/completion） \| 全部声明 \| ✔ \|
	25	+\| 3 \| 空诊断（有效代码） \| 诊断正确性基线：合法代码不误报 \| `[]` \| ✔ \|
	26	+\| 4 \| definition \| 跳转到定义（对应 VS Code F12） \| range 精准指向声明 line 0 char 5..10 \| ✔ \|
	27	+\| 5 \| hover \| 悬停显示函数签名 \| `internal func greet(name: String): String` \| ✔ \|
	28	+\| 6 \| documentHighlight \| 高亮同名出现处 \| 声明 line 0 + 调用 line 5 两处 \| ✔ \|
	29	+\| 7 \| semanticTokens \| 语义着色，仅验证非空+格式（不验证类型） \| data 45 项（9 token），长度为 5 的倍数 \| ✔ \|
	30	+\| 8 \| documentSymbol \| 文档大纲（Outline） \| `greet(String): String`、`main(): Int64` \| ✔ \|
	31	+\| 9 \| completion \| 补全须含上下文符号（msg/greet），防 length>0 假性通过 \| 44 项全为标准库全局符号，不含 greet/msg \| ✘ 暴露服务端不做作用域补全 \|
	32	+\| 10 \| references \| 查找所有引用 \| `null` \| ⊘ skip（known limitation） \|
	33	+\| 11 \| 错误诊断 \| 诊断敏感性基线：错误代码必报 \| 非空，含 message \| ✔ \|
	34	+
	35	+结论：服务端跳转/悬停/高亮/语义token/符号/诊断能力本身正常；补全不做上下文过滤是服务端真实短板。
	36	+
	37	+## 2. e2e direct 套件（9 项）：实测 4 通过 + 5 失败
	38	+
	39	+> 前提：插件 1.1.0 在 macOS 下 spawn LSPServer 时不传 `CANGJIE_HOME`、且总发无效 `stdLibPathOption`（SDK 0.6.2 无 `lib/src`），服务端无法定位标准库，语义结果全 null。

	41	+\| # \| 用例 \| 测试内容 \| 关键实际返回 \| 结论 \|
	42	+\|---\|---\|---\|---\|---\|
	43	+\| 1 \| 插件激活+TextMate 文法 \| e2e 入口，不依赖服务端 \| 激活、文法存在、语言注册 \| ✔ \|
	44	+\| 2 \| .cj 语言关联 \| languageId 为 Cangjie \| `Cangjie` \| ✔ \|
	45	+\| 3 \| 转到定义 \| executeDefinitionProvider \| `Timed out; last result: []` \| ✘ 如实暴露不可用 \|

	47	+\| 5 \| 高亮同名处 \| executeDocumentHighlights \| 断言被满足 \| ✔ 但系 VS Code word-based 兜底，假性通过 \|
	48	+\| 6 \| 语义 token \| provideDocumentSemanticTokens \| `Timed out; last result: undefined` \| ✘ 无兜底，如实暴露 \|
	49	+\| 7 \| 文档符号 \| executeDocumentSymbolProvider \| 空，greet 不在 \| ✘ \|
	50	+\| 8 \| 补全 smoke check \| executeCompletionItemProvider \| 非空 \| ✔ 但系 VS Code 兜底；服务端补全质量由 protocol 第 9 项验证 \|
	51	+\| 9 \| 有效代码无诊断 \| 前置先确认服务端已分析（防"未工作→无诊断"假阳性） \| 前置失败：Server did not analyze \| ✘ 如实暴露服务端未工作 \|
	52	+
	53	+结论：真实 VS Code 环境下跳转/悬停/语义高亮/符号/诊断 5 项能力全部失效（插件两缺陷所致）；文法高亮正常；补全/高亮的"通过"是 VS Code 兜底假性。
	54	+
	55	+## 3. 补充对照：completion 在不同位置的实际返回（探针）
	56	+
	57	+\| 触发位置 \| 实际返回 \| 含 greet/msg \|
	58	+\|---\|---\|---\|
	59	+\| `println(msg)` 内（标识符内） \| 44 项标准库全局符号 \| 否 \|
	60	+\| `let x = ` 后（典型表达式起始） \| 0 项 \| 否 \|
	61	+
	62	+两种位置均不返回上下文符号，证实服务端补全不具备作用域分析能力。
	63	+
	64	+## 4. 汇总与问题清单
	65	+
	66	+\| 套件 \| 通过 \| 失败 \| 跳过 \|
	67	+\|---\|---\|---\|---\|
	68	+\| protocol（直接服务端） \| 9 \| 1（补全短板） \| 1（references） \|
	69	+\| e2e direct（VS Code 集成） \| 4（含 2 项 VS Code 兜底假性） \| 5（服务端语义层失效） \| 0 \|
	70	+
	71	+\| 级别 \| 问题 \| 证据 \|
	72	+\|---\|---\|---\|
	73	+\| 🔴 插件缺陷 \| 启动 LSPServer 不传 `CANGJIE_HOME`，服务端找不到标准库 \| e2e 5 项失败；protocol 对照（正确传参则 9/10 通过） \|
	74	+\| 🔴 插件缺陷 \| 总发无效 `stdLibPathOption`（SDK 无 `lib/src`，getStdLibPath 回退路径亦非标准库） \| 同上；bundle 实现反混淆 + SDK 目录实测 \|
	75	+\| 🔴 服务端短板 \| 补全不做作用域过滤 \| protocol 第 9 项失败 + 探针对照 \|
	76	+\| 🟡 e2e 层局限 \| VS Code word-based 兜底掩盖补全/高亮失效 \| e2e 第 5/8 项假性通过 \|
	77	+\| 🟡 测试盲区 \| references 声明 provider 但返回 null \| protocol 第 10 项 skip \|
	78	+
	79	+下一步：向 Cangjie 插件方反馈两处缺陷（修复后 e2e direct 预期转绿）；服务端补全与 references 短板需服务端侧评估。
