egg 单元测试failing状态进程报错

Question

config.unittest.js代码如下

module.exports = appInfo => {
  /**
   * built-in config
   * @type {Egg.EggAppConfig}
   **/
  const config = {};

  // use for cookie sign key, should change to your own and keep security
  config.keys = appInfo.name + 'xxx';

  // config for error
  config.onerror = {
    json(err, ctx) {
      // json hander
      ctx.body = { message: err };
      ctx.status = 500;
    },
  };

  config.logger = {
    outputJSON: true,
    dir: path.join(appInfo.baseDir, 'logs'),
  };
  // add your user config here
  const userConfig = {};

  return {
    ...config,
    ...userConfig,
  };
};
