我正在将我的 react 应用程序更新为react-16，但我的所有测试都停止了。我已经升级了enzyme, jest-enzyme, react-dom, 安装了enzyme-adapter, 创建了setupTest.ts酶文件, 更新了我的jestconfig.js文件但我仍然收到错误。如果有人知道可能出了什么问题。

做时没有依赖警告（与反应|测试有关）npm ls

这是我的jestconfig

{
  "moduleDirectories": [
    "node_modules",
    "src"
  ],
  "moduleFileExtensions": [
    "ts",
    "tsx",
    "js"
  ],
  "moduleNameMapper": {
    "\\.(css|scss)$": "identity-obj-proxy"
  },
  "transform": {
    ".(ts|tsx)": "<rootDir>/node_modules/ts-jest/preprocessor.js"
  },
  "testResultsProcessor": "<rootDir>/node_modules/ts-jest/coverageprocessor.js",
  "snapshotSerializers": [
    "enzyme-to-json"
  ],
  "setupTestFrameworkScriptFile":"<rootDir>/config/setupTests.ts",
  "coveragePathIgnorePatterns": ["node_modules", "__tests__"],
  "testRegex": "__tests__/.*\\.test\\.(ts|tsx|js)$",
  "collectCoverageFrom": ["src/**/*.{ts,tsx}"],

...rest of code

src/setupTests.ts

import 'raf/polyfill'; // <= this removes the requestAnimationFrame warning error
import * as Enzyme from 'enzyme';
import * as Adapter from 'enzyme-adapter-react-16';

Enzyme.configure({ adapter: new Adapter() });
