I need to write test for LineMarkerProvider implementation, I found one example - org.jetbrains.plugins.groovy.lang.GroovyLineMarkerTest,
but it tests only markers that collected only by LineMarkerProvider#getLineMarkerInfo method.
I tried to find some example or flag in the com.intellij.codeInsight.daemon.impl.DaemonCodeAnalyzerImpl to enable collecting markers with collectSlowLineMarkers but didn't found yet.
Maybe someone know what should I do, or some example.
Thanks in advance!
