NestJS

Question

我已经用 NestJS + Apollo / Express 在我的 GraphQL 应用程序上解决 E2E 测试问题 3 天了。

当我运行我的应用程序使用 无服务器离线 或直接使用我的 主文件 时，它运行完美。我有我的图表和我需要的所有东西:)

但是，当我运行使用 Jest 进行 E2E 测试时，我从 beforeEach 中的 await app.init() 收到错误。

使用 package.json 和依赖项后，抛出的错误是 TypeError: (0 , schema_1.makeExecutableSchema) is not a function。

有人知道吗？我完全被封锁了......:(

经过数小时的紧张编程... 终于找到问题了

如果您对导入使用某些“别名”，请小心，因为它可能会覆盖某些已使用的包。

在这里，我使用了 @graphql 别名，它破坏了我所有的测试。当我删除它时，问题就消失了。

  moduleNameMapper: {
    '^@features/(.*)': '<rootDir>/src/features/',
    '^@tests/(.*)': '<rootDir>/__tests/',
    '^@utils': '<rootDir>/src/utils',
    '^@config': '<rootDir>/src/config',
    '^@types': '<rootDir>/src/@types',
    '^@graphql': '<rootDir>/src/@graphql/generated', // to remove
  },

至

  moduleNameMapper: {
    '^@features/(.*)': '<rootDir>/src/features/',
    '^@tests/(.*)': '<rootDir>/__tests/',
    '^@utils': '<rootDir>/src/utils',
    '^@config': '<rootDir>/src/config',
    '^@types': '<rootDir>/src/@types',
  },
