I am working on creating unit tests for my iOS portions of my shared library but I am running into issues copying resource files from my project onto devices and simulators for the test. Does anyone know of a way I can do this?

[Jan Holešovský]

Can you be more specific? What exactly do you do to copy the stuff (build.gradle.kts snippet eg.?), and what exact error message are you getting?

[hansenji]

I have a data file that I use for testing. On JVM unit tests I can access right from the resources folder but on iOS it isn't accessible from the simulator.

[hansenji]

If there is some way in code to include the resources directory in tests on the iOS device/simulator that would be amazing and simplify my unit tests so much.

[hansenji]

My current thoughts would be to Base64 the file and put that directly into my code and write it out at the beginning of the test, which makes maintenance a nightmare.

What works for me is that I have a folder with the files I need in the Resources of my iosApp, and I've added the folder via right-click on it, selected Add files to "iosApp", selected the folder (not the files!), and unchecked "Copy items if needed" and checked "Create folder references". That way, I can freely copy files into this folder, and they appear in the bundle. Then I can read them via Bundle.main.path(forResource: "name", ofType: "ext") (Swift) or NSBundle.Companion.mainBundle.pathForResource("name", "ext") (Kotlin). Is that what you are looking for?

[And just keep the folder empty for the release builds.]

Does this only work in xcode, or can I use that in Studio, and my build server?

[Jan Holešovský]

You have to do the initial set up in xcode, but then it is just a matter of doing the build.gradle.kts right, so I'd say you can do from Studio and build server too.
