ava 抛出 npm ERR！ sinon 存根引发新错误时测试失败

如何解决ava 抛出 npm ERR！ sinon 存根引发新错误时测试失败

我有以下测试到达端点。服务方法存根抛出错误。

应用程序中抛出的任何错误都由全局错误处理程序处理，处理程序返回状态为 500 的错误，例如：

{
  success: false,message: "Something went wrong!"
}

/* eslint-disable no-param-reassign */

const test = require('ava');
const sinon = require('sinon');
const request = require('supertest');

require('dotenv').config();

// dependency to be stubbed
const { CountryService } = require('../../src/components/country/country.component');

// stubs
const error = new Error('Some Error');
const doGetCountries = sinon.stub(CountryService,'doGetCountries').throws(error);
const app = require('../../src/app');

test.before(async (t) => {
  t.context.stubs = {
    doGetCountries,};
  t.context.apiUrl = '/api/v1/countries';
  t.context.server = request(app);
});

test.after.always((t) => {
  delete require.cache[require.resolve('../../src/app')]; // kills server
});

test('Throws Internal Server',async (t) => {
  const { server,apiUrl,stubs } = t.context;
  const res = await server
    .get(apiUrl)
    .set('accept','application/json');
  t.true(res.status === 500);
  t.true(stubs.doGetCountries.calledOnce);
});

当我运行测试时它失败了，但没有错误消息

npm ERR! Test Failed.  See above for more details.

如果执行 studb.resolve({}) 则测试通过。
