我正在使用 Restify，我正在尝试学习如何编写测试我的 CRUD 方法。当我连接到 DynamoDB 时，我可以在 Postman 上毫无问题地测试它们。对于测试，我将连接到在 localhost:8000 上运行的本地 DynamoDB。

上server.listen，我有这个：

dynamoose.AWS.config.update({
  accessKeyId: config.db.aws_access_key_id,
  secretAccessKey: config.db.aws_secret_access_key,
  region: config.db.aws_region
});

if (config.env == "test") {
  dynamoose.local();
}

（我也尝试调用dynamoose.local()上述更新）

当我使用mocha --timeout 10000命令运行测试时，出现以下错误：

1) Uncaught error outside test suite:

现在我知道这是一个问题，因为 dynamoose 无法配置区域。但是当我在开发中运行它时，它可以在同一段代码中正常工作。在我的配置文件中，我也有相同的数据库配置。我通过console.log(config.db)在 if中添加来验证这一点(config.env == "test")。所以我认为它应该配置。

如果需要，这是我的测试：

describe('ModelName', () => {
  beforeEach((done) => {
    ModelName.delete({}, (err) => {
      done();
    });
  });

  describe('/GET modelName', () => {
    it('it should GET all the model-name instances', (done) => {
      chai.request(server)
        .get('/model-name')
        .end((err, res) => {
            res.should.have.status(200);
            res.body.should.be.a('array');
            res.body.length.should.be.eql(0);
          done();
        });
    });
  });
});

任何想法可能是什么问题？

当您在本地运行时，您的区域将从位于的文件中获取

%UserProfile%\.aws\config

看起来像这样

[default]
region=us-west-2
output=json

我的猜测是，当您在服务器上运行时，块

dynamoose.AWS.config.update({
  accessKeyId: config.db.aws_access_key_id,
  secretAccessKey: config.db.aws_secret_access_key,
  region: config.db.aws_region
});

没有按照您的预期进行，但是当您在本地运行时，由于配置文件在您的配置文件中被拾取，问题就被隐藏了。

尝试将配置设置为文字region: 'us-west-2'，或者您可以设置凭据和配置是服务器上的环境变量（它们将被自动选择）。
