Hi all
I am working on REST API written in express where business logic is written in raw SQL queries.
I want to follow TDD for future development.But I am not able to find any resource to guide me on how to begin.
Could anyone please lead me in the right direction on how to write test ?

You have a couple of options:
There's not much to say about the first option. For the second, think of an API endpoint that creates a reservation for a hotel room. Your tests should initialize the database with one or more
users
and one or morerooms
(shameless plug: I wrote a thing that makes that a lot more manageable).Your basic test: given I already have
users
androoms
, I should be able to pass a request body with a user id, room id, and check in/out dates to my endpoint. After a successful request, I can retrieve a record fromreservations
matching my parameters. Access the database directly for setup and verification, but otherwise treat it as a "black box" and make sure you think through the different paths your logic takes based on the inputs you pass it.Hi Dian
Thank you for your reply.
I was not aware about the concept of fixtures.I will surely look into it.
