Branches coverage in Mockk Kotlin

Issue

I am using mockk library in Kotlin. I am covering branch coverage. I am new to testing. Can someone tell me how to cover all branches? In the given below example, it has two objects one is id as string and the name which is hidden is list. Thanks

Can someone explain what are the 12 branches are for this?

Solution

I can only count 9, but I might be missing something:

!id.isNullOrEmpty()	Reason	!xxx.isNullOrEmpty()	Reason
TRUE	id is not null and not empty	TRUE	xxx is not null and not empty
TRUE	id is not null and not empty	FALSE	xxx is empty
TRUE	id is not null and not empty	FALSE	xxx is null
FALSE	id is null	TRUE	xxx is not null and not empty
FALSE	id is empty	TRUE	xxx is not null and not empty
FALSE	id is null	FALSE	xxx is null
FALSE	id is null	FALSE	xxx is empty
FALSE	id is empty	FALSE	xxx is null
FALSE	id is empty	FALSE	xxx is empty
