Extra branches in the when statement (coverage)

Android

Trying to get code coverage with a “when” expression using Kover or Intellij Coverage Plugin. There are always extra branches that prevent you from achieving 100% coverage.

For example, the Intellij Coverage plugin and Kover show 9 branches:

private fun replaceGuid(guid: String): String {
        return when (guid) {
            "11" -> "11"
            "22" -> "22"
            "33" -> "33"
            else -> guid
        }
    }

If you rewrite the condition using “if”, there will be 4 branches.

Is there any way to fix this without changing the code of the class being tested or modifying the bytecode?
