如何设置另一个数据库以测试knexfile？

我有2个数据库;第一个用于开发和生产，第二个用于测试。 knexfile.js：如何设置另一个数据库以测试knexfile？

const config = require('config'); 

const knexConfig = config.get('knexConfig'); 

module.exports = { 

    development: { 
    client: knexConfig.client, 
    connection: { 
     host: knexConfig.host, 
     database: knexConfig.database, 
     user: knexConfig.user, 
     password: knexConfig.password, 
    }, 
    pool: { 
     min: knexConfig.min, 
     max: knexConfig.max, 
    }, 
    }, 
    test: { 
    client: 'sqlite3', 
    connection: { 
     filename: './file.db', 
    }, 
    }, 
};

route.test.js：

const的模型=要求（ '异议'）模型;

const provider = require('../../../server/models/provider'); 
const Knex = require('knex'); 
const knexConfig = require('../../../knexfile'); 

const knex = Knex(knexConfig.test); 
Model.knex(knex); 


describe('Should test provider Model',() => { 
    test('should return provider',() => { 
    provider 
     .query() 
     .then((providers) => { 
     expect(providers).toBe('array'); 
     }); 
    }); 
});

我得到这个错误：

Test suite failed to run 

    ProcessTerminatedError: cancel after 2 retries! 

     at Farm.<anonymous> (node_modules/worker-farm/lib/farm.js:87:25) 
      at Array.forEach (<anonymous>) 
     at Farm.<anonymous> (node_modules/worker-farm/lib/farm.js:81:36) 
     at ontimeout (timers.js:469:11) 
     at tryOnTimeout (timers.js:304:5) 
     at Timer.listOnTimeout (timers.js:264:5) 

A worker process has quit unexpectedly! Most likely this is an initialization error.

我想连接到SQLite数据库的测试，但我不能这样做，通过我tests.How可以解决呢？

哪些测试运行，你使用不包含查询？看起来你并没有等待异步代码在测试用例退出之前终止。 –

你的配置似乎很好，因为下面的测试工作。

https://runkit.com/embed/3w0umojslatc

require('sqlite3'); 
var knex = require("knex")({ 
    client: 'sqlite3', 
    connection: { 
    filename: './db.db' 
    } 
}) 

const { Model } = require('objection'); 
Model.knex(knex); 

await Model.query().select('1');

看起来你混合DBB和TDD语法和测试返回之前有没有等待异步结果有一定误差。

先尝试这样的：

const Model = require('objection').Model; 
const provider = require('../../../server/models/provider'); 
const Knex = require('knex'); 
const knexConfig = require('../../../knexfile'); 

const knex = Knex(knexConfig.test); 
Model.knex(knex); 


describe('Should test provider Model',() => { 
    it('should return provider',() => { 
    return Model.query().from('providers') 
     .then((providers) => { 
     expect(providers).toBe('array'); 
     }); 
    }); 
});

如果这样的作品，然后尝试做自己providers类，您已经在问题
