elvis operator to provide a default:
If I have reasonable tests around code that does something like:
val x = nullableObject?.method() ?: default
JaCoCo tells me I have one of 4 branches uncovered.
If I change that to:
val nullableX = nullableObject?.method()
val x = nullableX ?: default
JaCoCo tells me all branches are covered (2 branches per line).
I'm guessing the "uncovered" branch is when nullableObject
is non-null, but method()
returns null -- is there a way to get JaCoCo to realize that branch is not possible based on method()
not being nullable? Or is there a better practice here?elizarov
