I have all my tests in

commonTest

. Is it possible to choose just one target to run the tests?

You could mark the test tasks you don't want to run as enabled = false

Ah, true.

No prob!

You can also do something like

@OptionalExpectation expect annotation class SinglePlatformTest

and then for the platform you’re interested do

actual annotation class SinglePlatformTest = kotlin.Test

. Then annotate tests with

@SinglePlatformTest

if you want them to only run on that platform. This pattern can give you pretty fine-grained control over which tests run on which platforms.
