Branches coverage in Mockk Kotlin

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

enter image description here

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
