I was trying to deploy on MavenCentral the artifacts generated with a script similar to yours exposed in this repository, but I've encountered an error
due to "wrong repository name". I have no idea what it is and where to set it in my build script. Furthermore on Maven Central Gradle guide there is no reference at all about this "repository name".

For reference the build script is this one.

Common Tests don't actually run for JS modules. I noticed it locally, and then I was able to confirm the same result on the lib-with-tests module example provided in this repo. If I add a failing test to a common module, and then run the jsTest command, the tests won't actually be run, and the build will pass.

The subject says it all. Please provide an example of configuring and running tests for iOS frameworks with the kotlin multiplatform plugin.

It is possible to publish a common only library with expect statements without any targets or actuals?

Then client projects can depend on this library and implement the actuals.

If its possible could you add an example?

I did attempt this and a project without any targets compiles without error but depending on that library gives:
