In the last couple of months, I have been working extensively with TypeORM and built many projects using this ORM. Setting up a test database for my unit tests was quite challenging. To overcome this, I mocked TypeORM methods to avoid interacting with a real database. However, I found myself copying the same mock code into every new project repeatedly. To streamline this process and help others facing the same issue, I decided to create a package. Initially, I mocked all the TypeORM code using Vitest, but that only worked in the Vitest environment. Since many developers use different testing frameworks such as Jest, Mocha, etc., I needed a more versatile solution. Hence, I used Sinon for mocking TypeORM, which is compatible with various testing frameworks.
