我对Mocha、Chai和单元测试有点陌生。我正在尝试编写一个基本的测试来检查通过我的中间件发出的请求中是否存在授权头。我尝试了一些方法，从传递TypeError到throw()以及消息和Error，没有运气....任何帮助都将不胜感激。

我的中间件

exports.verify = async (req, res, next) => {
      try {
        const headers = req.get('Authorization');
        let decodedToken;
    
        if (!headers) {
          const error = new Error('Not Authenticated');
          error.statusCode = 401;
          throw error;
        }
        const token = headers.split(' ')[1];
    
        try {
          decodedToken = jwt.verify(token, SECRET);
        } catch (err) {
          err.statusCode = 500;
          throw err;
        }
    
        if (!decodedToken) {
          const error = new Error('Not Authenticated');
          error.statusCode = 401;
          throw error;
        }
    
        req.userUid = decodedToken.userUid;
    
        const queryRef = await users.where('uid', '==', req.userUid).get();
    
        if (queryRef.empty) {
          const error = new Error('Not Authenticated');
          error.statusCode = 401;
          throw error;
        } 
        next();
      } catch (err) {
        log.error(err);
        next(err);
      }
    };

我的测试

it('Should throw an error if no auth header provided.', function () {
  const req = {
    get: function () {
      return null;
    },
  };

  expect(function () {
    verify(req, {}, () => {});
  }).to.throw();
});

• 以防万一 * -在app.ts处处理错误

app.use((err, req, res, next) => {
  const status = err.statusCode || 500;
  const message = err.message;
  const data = err.data || [];
  const userUid = req.userUid;
  const stack = err.stack;
  log.error(`STATUS: ${status} - MESSAGE: ${message} - STACK: ${stack}`);
  res.status(status).json(message);
});
