Describe the problem（描述问题）

操作步骤

1. 下载最新包

npm init midway@latest -y

2. 选择 egg-v3
3. 进入项目并下载依赖
   cd midway-project cnpm install
4. package.json新增jest执行命令
   "nodetest": "jest",
5. 运行单测
   npm run nodetest
6. 抛出异常

  console.error
      TypeError: Cannot use 'in' operator to search for 'enable' in 105
          at EggAgentWorkerLoader.normalizePluginConfig (D:\eggtest\midway-project\node_modules\_egg-core@4.31.0@egg-core\lib\loader\mixin\plugin.js:219:20)
          at EggAgentWorkerLoader.readPluginConfigs (D:\eggtest\midway-project\node_modules\_egg-core@4.31.0@egg-core\lib\loader\mixin\plugin.js:194:14)

7. 删除对应文件
   src>config>plugin.ts
   8.再次执行单测
   9.运行正常
   ` PASS test/controller/api.test.ts
   PASS test/controller/home.test.ts
   A worker process has failed to exit gracefully and has been force exited. This is likely caused by tests leaking due to improper teardown. Try running with --detectOpenHandles to find leaks. Active timers can also cause this, ensure that .unref() was called on them.

这是 egg 的报错，你必须使用 ts-node 来执行。

"test": "cross-env NODE_ENV=unittest NODE_OPTIONS=--require=ts-node/register jest",
