I have a
data class A(){
fun c(){}
} .
I need to create a fake implementation of it for testing, but it says that class must be open. open modifier is incompatible with data class. Any ways to do it?

2Why must you use a fake? What is the real one doing that you want changed in your tests?Michael– Michael2019-08-21 18:03:48 +00:00Commented Aug 21, 2019 at 18:03

In need of multiple versions of the same class? You are supposed to use an interface then. Mocking becomes easy when you write proper OOP code.Mike Doe– Mike Doe2019-08-21 18:04:27 +00:00Commented Aug 21, 2019 at 18:04

To mock final classes update mockito
testCompile 'org.mockito:mockito-core:2.8.9'
and then add a folder in your resources folder called mockito-extensions that includes a text file called org.mockito.plugins.MockMaker. Inside there just add
mock-maker-inline
That should solve your problem
