Unit Testing on Strapi 4

Questions and Answers

I’m trying to run this test on sqlite, but seems like I’m unable to persist data after using the entityService:

import request from 'supertest'
import {
  setPublicPermissions,
  updatePluginStore,
  setupStrapi,
  stopStrapi,
  sleep
} from './../helpers/strapi'

import { describe, beforeAll, afterAll, it, expect, test } from '@jest/globals'

/** this code is called once before any test is called */
beforeAll(async () => {
  await setupStrapi()
})

/** this code is called once before all the tested are finished */
afterAll(async () => {
  await stopStrapi()
})

describe("Library's tests", () => {
  beforeAll(async () => {
    await setPublicPermissions({
      library: ['find', 'findOne']
    })
  })

  it('should return an empty list of libraries', async () => {
    await request(strapi.server.httpServer)
      .get('/api/libraries')
      .expect(200)
      .then(res => {
        expect(res.body.data).toStrictEqual([])
      })
  })

  it('should return a list of libraries', async () => {
    const createdLibrary = await strapi.entityService.create(
      'api::library.library',
      {
        data: {
          title: 'My first library',
          copies: 1
        }
      }
    )
    console.log(createdLibrary)

    expect(createdLibrary.title).toBe('My first library')

    await request(strapi.server.httpServer)
      .get('/api/libraries')
      .expect(200)
      .then(res => {
        expect(res.body).toBeDefined()
        expect(res.body.data.length).toBe(1)
        expect(res.body.data).toStrictEqual([])
      })
  })
})
