dataBinding { enabled = true } - I don't think this changes in Kotlin, so try it with a = in your build.gradle file. — yennsarah

@Amylinn I do confirm that data binding works when I run application in IDE. It fails only when I try to run test. I changed as you mentioned, it doesn't work either. — Trevor Wang

You need to add apply plugin: 'kotlin-kapt' to your application gradle file. Explanations in this article (New Experimental Annotation Processing) https://blog.jetbrains.com/kotlin/2016/09/kotlin-1-0-4-is-here/#sthash.y5NtHdYW.dpuf

Right but (I haven't dig to exact reason) you should explicitly specify this plugin in gradle. In my project it used to work before I had been updated to kotlin 1.1 @TrevorWang
