I would like to test my mapper class at 100%.
For that, I wrote a test that takes all possible values.
With the reports made by Kover, we can see that everything is green (except the first line).
I'm use kover_version = '0.6.1' with minimal settings
Here is the class to test :
object WeatherIconMapper {
fun mapCodeToWeatherIcon(code: String?): Int = when (code) {
"p1j", "p1bisj" -> R.drawable.ic_wicon_p1j_p1bisj
"p1n", "p1bisn" -> R.drawable.ic_wicon_p1n_p1bisn

}
And the associate test :

@Test
fun `test getWeatherIcon mapper`() {

Kover coverage report :
...
Why the conditions coverage is not 100 % ?
Edit:
I just noticed that before switching to Kover, the code was 100% tested with Jacoco :
