Unit testing

Use the no-op testing module so @Transactional() methods run without real transactions and @InjectPrismaClient() resolves a proxy over your mock client:

import { createNoOpPrismaTransactionalModule } from '@nestjs-transactions/prisma/testing';

const mockClient = { user: { create: jest.fn() } };
const moduleRef = await Test.createTestingModule({
  imports: [createNoOpPrismaTransactionalModule({ client: mockClient })],
  providers: [UserService],
}).compile();

Transaction hooks still fire. Pass connectionName to stand in for a named connection.
