NX工作区和打字稿中的cucumber-js，找不到模块（共享库）

问题描述 投票：0回答：1

我有一个 NX 工作区，其中包含 Angular 和 NestJS。我还有一些共享库。我想测试一个 NestJS API 项目，该项目使用使用

生成的共享库之一 
nx g @nrwl/nest:lib shared/backend

我只是在我的 NestJS 项目中使用它，就像通过 NX 分配的名称进行正常导入一样。当我在开发模式下运行项目本身时效果很好，但是当我使用 @nestjs/testing 模块运行应用程序时，它会失败。

Error: Cannot find module '@proj/shared/backend'

当从我的 API 代码中删除库引用时，我的测试运行良好，因此它实际上只在黄瓜测试中。这是我创建测试模块的方法：

const moduleFixture: TestingModule = await Test.createTestingModule({
  imports: [AppModule],
}).compile();
this.context.app = moduleFixture
  .createNestApplication()
  .useGlobalPipes(new ValidationPipe());
await this.context.app.init();

要启动 e2e 测试，我调用以下命令：

cucumber-js -p proj-api

我的 tsconfig.json 看起来像这样：

{
    "compileOnSave": false,
    "compilerOptions": {
        "rootDir": ".",
        "sourceMap": true,
        "declaration": false,
        "moduleResolution": "node",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "importHelpers": true,
        "target": "es2015",
        "module": "esnext",
        "lib": ["es2017", "dom"],
        "skipLibCheck": true,
        "skipDefaultLibCheck": true,
        "baseUrl": ".",
        "paths": {
            "@proj/shared/backend": [
                "libs/shared/backend/src/index.ts"
            ],
            "@proj/shared/client": [
                "libs/shared/client/src/index.ts"
            ],
            "@proj/shared/common": [
                "libs/shared/common/src/index.ts"
            ],
            "@proj/shared/eds": [
                "libs/shared/eds/src/index.ts"
            ],
            "@proj/shared/feature": [
                "libs/shared/feature/src/index.ts"
            ]
        }
    },
    "exclude": ["node_modules", "tmp"]
}

我的 cucumber.js 在 root 中

module.exports = {
  'proj-api': [
    'apps/proj-api-e2e/features/**/*.feature', // Specify our feature files
    '--require-module ts-node/register', // Load TypeScript module
    '--require apps/proj-api-e2e/step-definitions/**/*.ts', // Load step definitions
    '--format progress-bar', // Load custom formatter
    '--publish-quiet',
    '--parallel 0',
    '--exit',
  ].join(' '),
};

这是我在 package.json 中的依赖项

看起来 cucumber-js 没有使用定义库的 tsconfig，因为当我正常运行代码时它可以工作，当我删除 lib 导入时我的测试也可以工作。

有人有什么想法吗？

typescript nestjs cucumberjs nx-workspace

安装 tsconfig-paths

npm install --save-dev tsconfig-paths

在cucumber.js（root）中注册模块

./node_modules/.bin/cucumber-js ... \
   --require-module ts-node/register \
   --require-module tsconfig-paths/register \
   ...

享受编码的乐趣！
