Hello everyone,
What do I return when I don't care about the return value?
I can't return unit since the return type is SomeClass . Do I have to return SomeClass() or is there something else available like return any or return whatever?

off the top of my head i’d say you can use a relaxed mock.
Can you please provide a full example of your problem though?

[Michael Vandendriessche]

I'm testing a function with this line

batteryImage.setImageDrawable(context.getResources().getDrawable(R.drawable.battery_100));

I'm mocking getDrawable, I don't care what it returns I just want to verify it was called with R.drawable.battery_100. And I do not want to execute the getresources and getdrawable.
I know it's not ideal code to unit test but it's what I have right now. Fixing these thingsi s on the planning for later.
Thanks for your reply!

you can either use justRun or use a relaxed mock.

[Michael Vandendriessche]

@christophsturm ah yes instead of every? Sorry I forgot about that one, I was trying just Runs as return value. Thanks!

[christophsturm]

I think just run as return value should also work

[Michael Vandendriessche]

just only works on Unit

[Mattia Tommasone]

yep that’s right just runs can only be used on methods returning Unit.
i’d say your best option is to use a relaxed mock

[Michael Vandendriessche]

I'm happy with the justRun, I will consider relaxed mock when I have more cases like this. Thanks!
