A modern programming language that makes developers happier.

kotlinlang

i am writing unit tests for my repository that uses sqldelight for it’s data. I was hoping to mock out the generated queries class with my own in memory version. I cannot extend the queries class since it is not `open`. is there any suggested alternative to achieve this?

If it's sqlite use an in-memory database. If it's mysql or postgres then I would suggest a testcontainers rule.

You can look at our own tests which do this

interesting that you suggest in memory database with sqlite but not postgres (im intrigued because im an android dev so 99% sqlite, but dipping my toes into ktor server with postgres!)

Testcontainers is effectively in memory postgres

Alternatively, you can mock your repository, if you use a repository architecture.
