Has anyone tried writing tests for incremental scenarios? I don’t think it’s currently possible with

kotlin-compile-testing

(e.g. it fully wipes output directories on each KSP run, and a bunch of the KSP incremental behaviour is implemented by the Gradle plugin rather than the compiler plugin). Is my best bet more of an integration test, maybe using Gradle TestKit?

we have some integration tests for incremental scenario in KSP code, we use gradle runner to simulate incremental scenarios, hope this can help.

Ah yeah that’s helpful, thanks! I need to figure out how to inject my real symbol processor into the test rather than one from a module in the test project, but that seems doable, probably with an included build.
