The main dependencies for our exercise will include TypeScript, NestJS, Jest as our unit and integration test-runner (included in Nest), PostgreSQL, MikroORM for use in our data persistence abstraction layer, and Docker Compose to help us run our integration tests. From here you should have a good foundation to build more tests. You can add the following class to your project: In the above example for beforeAll() there was a commented-out line app.useLogger(new TestLogger()). A progressive Node.js framework for building efficient and scalable server-side applications..
