Jest timeout testing Koa route - automated-tests

Question

I am starting with Jest for testing our API. However, the moment I add my second test, everything falls apart with a timeout exception.
Here's my code:
const server = require('../server')
const request = require('supertest')
const path = require("path")
const fs = require("fs")
const config = require('../knexfile.js')
const knex = require('knex')(config.development)
beforeAll(async () => {
let file = fs.readFileSync(path.join(__dirname, '..', 'galaxycard.sql'), 'utf8')
await knex.raw(file)
await knex.migrate.latest()
})
afterAll(async () => {
await knex.raw(`
DROP SCHEMA public CASCADE;
CREATE SCHEMA public;
GRANT ALL ON SCHEMA public TO public;
`)
server.close()
})
describe("test 1", () => {
it("should not be able to add a payment for user without credit", async () => {
let response = await request(server)
.post('/v1/hampers')
.set('Content-Type', 'application/json')
.send({
entity_type: 'utility',
latitude: 1,
longitude: 1,
comment: null,
user_id: new Date().getTime(),
amount: -200,
entity_id: 1,
processed: false
})
expect(response.status).toEqual(402)
})
})
describe("test 2", () => {
let userId
beforeEach(async () => {
userId = new Date().getTime()
let response = await request(server)
.post('/v1/hampers')
.set('Content-Type', 'application/json')
.send({
entity_type: 'credit',
latitude: 0,
longitude: 0,
user_id: userId,
amount: 5000,
entity_id: 1,
processed: true
})
expect(response.status).toEqual(200)
expect(JSON.parse(response.text)).toHaveProperty('uuid')
})
it("have hampers", async () => {
let response = await request(server)
.post('/v1/hampers')
.set('Content-Type', 'application/json')
.send({
entity_type: 'utility',
latitude: 1,
longitude: 1,
comment: null,
user_id: userId,
amount: -200,
entity_id: 1,
processed: false
})
expect(response.status).toEqual(200)
expect(JSON.parse(response.text)).toHaveProperty('uuid')
})
})
Jest keeps dying with:
Timeout - Async callback was not invoked within the 5000ms timeout
specified by jest.setTimeout.
Another weird issue is that Jest doesn't exit after the tests have run, even though I use server.close.

Answer 1

The second issue (seeming to hang after the test run) is probably caused by the lack of knex.destroy() in your afterAll. I can speak to the first problem after seeing your route definition.
