It's based off of the guides but i used Javascript instead of Typescript.

That's actually pretty cool thanks man I hope this gets into the documentation soon

I'll add a similar example to the Prisma Example repository so it can be easy for our users to find.

Pardon but it should work with es6 right? Or does it need more configuration?

OsamuOP•3mo ago

I'm trying to use es6

RaphaelEtim•3mo ago

You need to configure Jest to support ES6 module. You could check resources online on how to do that

Thank you

RaphaelEtim•3mo ago

You're welcome

Testing with ES6 requires to install jest-mock-extended and to create a file, the name can be anything:

import { mockDeep, mockReset } from "jest-mock-extended";

import { prisma }  from './utils/prisma'

jest.mock('./utils/prisma', () => ({
  prisma: mockDeep(),
// The line to activate es6, without it you'll get an error
  __es6: true
}))

beforeEach(() => {
  mockReset(prismaMock)
})

const prismaMock = prisma

export default prismaMock

import { mockDeep, mockReset } from "jest-mock-extended";

import { prisma }  from './utils/prisma'

jest.mock('./utils/prisma', () => ({
  prisma: mockDeep(),
// The line to activate es6, without it you'll get an error
  __es6: true
}))

beforeEach(() => {
  mockReset(prismaMock)
})

const prismaMock = prisma

export default prismaMock

Then, you can mock the api as you like
