Review on Mockito by Tim Ram

It's easy to use, it has great documentation (even though sometimes can be outdated), I've never had any problems using this library when developing my android applications with Kotlin! The only thing is that if you are newbie like me or don't have enough experience working/developing java code then maybe some features might look strange at first but after reading its docs everything will become clear :) Great toolkit which helps us write better test cases before writing our actual application logic without worrying about whether we won’t break anything while doing so because of null pointer exceptions etc..
