If you’re a backend developer, you may be fazed by data-driven API development. In this article, you’ll learn about TypeORM, one of the most popular JavaScript object-relational mappers, by creating a Node.js application with TypeORM and TypeScript.TypeORM aims to optimize and simplify writing long and complex SQL queries, making the task less stressful. Unfortunately, while Jest exposes the JEST_WORKER_ID environment variable to distinguish between workers, it doesn't expose any simple way of hooking in per-worker setup and teardown methods.. This means that we can't dynamically spin up and tear down databases for each worker. We can, however, do the next best thing, using a static number of Jest workers. Database seeding can be done in different contexts, from inserting random batches so that we can test our application faster (which helps in our development experience), but we can also define an array of objects that can be data. admin accounts or simply data that needs to be used in the production environment.
I went with the in-memory database solution. This way I don't have to mock the complex queries of TypeORM. The unit tests run as fast without hitting the real database.
