【问题描述】：
我目前正在 Heroku 上使用 Swagger 构建 API，我想尝试端点是否在 Postgre 数据库中创建正确的条目。但是，一旦我尝试在我的测试环境中连接到 Heroku 的 Postgre，连接就会被拒绝。我认为这是因为在持续集成环境中，heroku 创建了一个沙箱并且不接受与真实数据库的连接。
我尝试按照此处的建议创建备份数据库：https://devcenter.heroku.com/articles/heroku-postgres-backups 但我找不到要访问的信息！
感谢任何帮助！
谢谢。
这是我的代码测试：
'use strict';
var should = require('should');
var request = require('supertest');
var assert = require('assert');
var server = require('../../../app');
var pg = require('pg');
var knex = require('knex')({
client: 'postgresql',
connection: process.env.DATABASE_URL
});
describe('controllers', function () {
describe('testing cenas', function () {
it('test1', function (done) {
request(server)
.get('/hello')
.set('Accept', 'application/json')
.expect('Content-Type', /json/)
.expect(200)
.end(function (err, res) {
assert.equal(res.body, 'Hello,Hugo Pereira!');
done();
});
});
});
});
它给出了一个错误：

原来是我的错误，你需要在测试环境中定义你的 process.env.DATABASE_URL
