ISSUE-2: KotlinNullPointerException during replay of a recorded test case #2

Closed mmilella94 closed 3 years ago

mmilella94 commented 5 years ago

I am using DM2 to perform capture and replay of automatically generated test cases. For certain applications, when replaying the recorded test cases, DM2 crashes with “kotlin.KotlinNullPointerException”

This happens for Version: 1.10 ( com.lubosmikusiak.articuli.derdiedas, downloaded from https://www.apkmonk.com/app/com.lubosmikusiak.articuli.derdiedas/ ).

This is the stack trace
