      精准测试在评估需求的测试范围时，需要评估一下代码的影响范围，这个范围有两部分：一是需求直接修改的代码；二是修改代码影响到的功能模块。代码影响到的功能一般是通过调用链路分析来实现的，java和kotlin代码可以由java-callgrap来分析出来调用链路，iOS 的OC和Swift可以使用clang来编译生成，前端貌似没有直接可用的工具。

一，技术调研

通过在网上进行不断的搜索和尝试，最终找到如下两个工具：

1，开源工具：dependency-cruiser

1.1 项目地址：GitHub - sverweij/dependency-cruiser: Validate and visualize dependencies. Your rules. JavaScript, TypeScript, CoffeeScript. ES6, CommonJS, AMD.

1.2 使用方法

（1）安装与初始化

在要生成调用关系的项目中，安装dependency-cruiser：

npm install --save-dev dependency-cruiser # or yarn add -D dependency-cruiser pnpm add -D dependency-cruiser

再初始化一下项目目录：

npx depcruise --init

（2）生成调用关系数据

• 生成全项目文件间的调用关系图

src/API/api.ts → src/API/controller/commonCntroller/commonController.ts src/API/api.ts → src/API/controller/configurationController/Configuration.ts src/API/api.ts → src/API/controller/covController/covController.ts src/API/api.ts → src/API/controller/recommendController/recommendController.ts src/API/api.ts → src/API/controller/report/report.ts src/router/routes/caseRecommend.ts → 
src/views/CaseRecommend/CaseRecommend.vue 
src/router/routes/caseRecommend.ts → src/views/CaseRecommend/CaseRecommendList/CaseRecommendList.vue src/router/routes/caseRecommend.ts → src/views/CaseRecommend/mobileCaseRecommend/mobileCaseRecommend.vue src/router/routes/caseRecommend.ts → src/views/Layout/Layout.vue src/views/CaseRecommend/CaseRecommend.vue → src/views/CaseRecommend/CaseRecommendRecord/CaseRecommendRecord.vue src/views/CaseRecommend/CaseRecommend.vue → src/views/CaseRecommend/SelectSearchModel/SelectSearchModel.vue src/views/CaseRecommend/CaseRecommend.vue → node_modules/vue-property-decorator/lib/vue-property-decorator.umd.js src/views/CaseRecommend/CaseRecommendRecord/CaseRecommendRecord.vue → src/API/api.ts ......

• 生成全项目页面间的调用关系文本文件

npx depcruise src --focus "^src" --output-type text >all_pageanlys.text

生成的内容为项目中各个文件间的调用关系，如下所示：

src/API/api.ts → src/API/controller/commonCntroller/commonController.ts src/API/api.ts → src/API/controller/configurationController/Configuration.ts src/API/api.ts → src/API/controller/covController/covController.ts src/API/api.ts → src/API/controller/recommendController/recommendController.ts src/API/api.ts → src/API/controller/report/report.ts src/router/routes/caseRecommend.ts → src/views/CaseRecommend/CaseRecommend.vue src/router/routes/caseRecommend.ts → src/views/CaseRecommend/CaseRecommendList/CaseRecommendList.vue src/router/routes/caseRecommend.ts → src/views/CaseRecommend/mobileCaseRecommend/mobileCaseRecommend.vue src/router/routes/caseRecommend.ts → src/views/Layout/Layout.vue src/views/CaseRecommend/CaseRecommend.vue → src/views/CaseRecommend/CaseRecommendRecord/CaseRecommendRecord.vue src/views/CaseRecommend/CaseRecommend.vue → src/views/CaseRecommend/SelectSearchModel/SelectSearchModel.vue src/views/CaseRecommend/CaseRecommend.vue → node_modules/vue-property-decorator/lib/vue-property-decorator.umd.js src/views/CaseRecommend/CaseRecommendRecord/CaseRecommendRecord.vue → src/API/api.ts ......

• 生成指定目录的调用关系

npx depcruise src --focus "^src/views" --output-type text >all_pageanlys.text

2，开源项目：ts-dependency-graph

2.1 开源地址

 URL:GitHub - PSeitz/ts-dependency-graph: prints a dependency graph in dot format for your typescript/react project

安装工具：

npm i ts_dependency_graph -g

2.2 生成调用关系数据

ts_dependency_graph --start apps > all_pagetanlys.txt

生成的数据如下所示：

在文件中有调用关系信息：

apps/quick-process-plus-e2e/src/e2e/app.cy.ts" -> "apps/quick-process-plus-e2e/src/support/app.po.ts" [color = "#F74B5F"] 
"apps/quick-process-plus-e2e/src/support/e2e.ts" -> "apps/quick-process-plus-e2e/src/support/commands.ts" [color = "#8D9B0D"] 
"apps/quick-process-plus/src/components/pc/select/index.ts" -> "apps/quick-process-plus/src/components/pc/select/common-select.tsx" [color = "#8B13D9"] "apps/quick-process-plus/src/components/pc/select/index.ts" -> "apps/quick-process-plus/src/components/pc/select/people-select.tsx" [color = "#8B13D9"] "apps/quick-process-plus/src/components/pc/select/index.ts" -> "apps/quick-process-plus/src/components/pc/select/dept-select.tsx" [color = "#8B13D9"] "apps/quick-process-plus/src/components/pc/select/people-select.tsx" -> "apps/quick-process-plus/src/components/pc/select/common-select.tsx" [color = "#A5F9DE"] "apps/quick-process-plus/src/components/pc/select/dept-select.tsx" -> "apps/quick-process-plus/src/components/pc/select/common-select.tsx" [color = "#44A823"] "apps/quick-process-plus/src/models/apiManage.ts" -> "apps/quick-process-plus/src/types/apiManage.ts" [color = "#6305F5"] "apps/quick-process-plus/src/models/app.ts" -> "apps/quick-process-plus/src/models/index.ts" [color = "#42F55F"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/user.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/tenant.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/auth.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/metadata.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/app.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/form.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/view.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/flow.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/corporation.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/page.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/formRender.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/formDesign.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/formComponent.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/process.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/target.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/global.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/formula.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/apiManage.ts" [color = "#D4502A"] "apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/processManagement.ts" [color = "#D4502A"]

需要使用python文件进行过滤，去掉后面的color信息，最终得到：

"apps/quick-process-plus/src/models/app.ts" -> "apps/quick-process-plus/src/models/index.ts" 
"apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/user.ts" 
"apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/tenant.ts""apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/auth.ts" 
"apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/metadata.ts" 
"apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/app.ts""apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/form.ts" 
"apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/view.ts" 
"apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/flow.ts" 
"apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/corporation.ts""apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/page.ts" 
"apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/formRender.ts" 
"apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/formDesign.ts" 
"apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/formComponent.ts" 
"apps/quick-process-plus/src/models/index.ts" -> "apps/quick-process-plus/src/models/process.ts"

再利用ccg生成调用关系数据。

二，调用关系技术方案

通过上面的两个基础工具，我们可以生成Vue和React项目文件间的调用关系，这个文件是脚本文件和页面问题，没有样式文件，在这些数据基础上，再对文件进行过滤和整理，就能生成符合要求的调用关系数据。

1，调用链路生成方案

整体方案如下：

• 通过工具生成调用关系数据，过滤相应的文件，如果是页面文件间的调用关系，说明是组件和页面的关系，直接存储；
• 如果是脚本文件，可以分析脚本文件被调用的页面文件，找出其调用的脚本文件中的函数以及调用行号，生成：脚本文件：函数-->页面文件：[开始行号，结束行号]的调用关系；
• 如果是样式文件，分析样式文件的被调用页面文件，分析页面文件调用样式文件中的样式函数的行号，生成：样式文件：函数-->页面文件：[开始行号，结束行号]的调用关系；
• 将上面三种调用关系数据入到CCG中生成调用关系数，并存储到文件中以便后续查询；
• 根据diff文件，改动的行号等信息，查询CCG文件，生成调用关系数据，存储到数据表中。

主要功能实现介绍：

• 生成调用关系数据在FEAgent上，下载相应的项目代码，安装工具生成调用关系数据；
• CCG通过调用FEAgent上的接口，下载调用关系数据，解压数据并生成树型调用关系，保存到pickle文件中；
• CCG提借查询调用关系的接口，供精准测试平台调用生成调用链路。

2，现存的问题

由于时间原因，上面的调用关系方案，只很简单地实现了文件间的调用关系，存储页面文件间的调用关系，脚本文件与页同文件间的调用关系，而且没有细化到函数级别；主要原因在于：

• 没有细化脚本文件到页面文件间的，函数与行号的对应关系，这个没有工具直接实现，需要编码进行过滤；
• 没有生成样式文件到页面文件间的调用关系，因为同级目录下的调用关系可以生成，跨目录的同名文件无法扫描出调用关系；
• 没有过滤样式文件到页面文件间的函数调用与行号间的关系，功能暂时没有开发。
• 过滤过细的调用关系，可以在后续推荐中做的更加精细，但也存在着文件过多的时候，性能较慢的问题。
• 后面看领导的重视程度，再安排细化工作。
