tests/.../prisma/helpers/singleton.ts Copy code
import { PrismaClient } from '@prisma/client';
import { mockDeep, mockReset, DeepMockProxy } from 'jest-mock-extended';
import prisma from '@infra/data/postgres/prisma/helpers/prismaClient';
jest.mock('@infra/data/postgres/prisma/helpers/prismaClient', () => ({
__esModule: true,
default: mockDeep<PrismaClient>(),
}));
beforeEach(() => {
mockReset(prismaMock);
});
export const prismaMock = prisma as unknown as DeepMockProxy<PrismaClient>;Mateus Silva

beforeAll(() => {
email = '<mailto:valid@mail.com|valid@mail.com>';
prismaMock.account.findUnique.mockResolvedValue({
id: 'validId',
email: '<mailto:valid@mail.com|valid@mail.com>',
password: 'validPassword',
active: true,
role: 'STUDENT',
createdAt: new Date(),
updatedAt: new Date(),
});
});
it('should return an account if email exists', async () => {
const account = await sut.findByEmail({ email });
expect(account).toBeTruthy();
});Mateus Silva

Copy code
prismaClient.account.findUnique = jest.fn().mockResolvedValue({
id: 'validId',
email: '<mailto:valid@mail.com|valid@mail.com>',
password: 'validPassword',
active: true,
role: 'STUDENT',
createdAt: new Date(),
updatedAt: new Date(),
});Mateus Silva
