未捕获的TypeError：this.buf.latin1Write不是函数

Question

运行测试文件时，我的测试通过了，但是beforeEach挂钩失败，并显示消息Uncaught TypeError: this.buf.latin1Write is not a function

我添加了testdouble，并将replace和require移到了before钩子内。

const td = require('testdouble');

suite('test', function() {

  // This is what fails
  setup(function() {
    sentry = td.replace('../../../lib/sentry');
    errors = require('../../../lib/errors');
  });

  suite('another test', function() {
    test('', function() {
      // some assertions here
    })
  });
});
