How to set another database for test on knexfile? - node.js

Question

I have 2 databases; the first for the developement and production and the second for the test.
knexfile.js:
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 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', () => {
test('should return provider', () => {
provider
.query()
.then((providers) => {
expect(providers).toBe('array');
});
});
});
I got this error:
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>)

A worker process has quit unexpectedly! Most likely this is an initialization error.
I want to connect to sqlite database for the test but I can't do that to pass tests.How can I fix that?

Your config seems to be fine, since following test works.
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');
Looks like you are mixing DBB and TDD syntax and have some error of not waiting async results before returning from test.
Try first this:
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');
});
});
});
If that works then try to do the query with your own providers class that you hadn't included in question
