Hey guys, I am getting weird issue when running on my unit test. I have this function

internal fun getPendingStatusAction(
status: XYZ
): (() -> Unit)? {
    var action: (() -> Unit)? = null
    this.yo = yo
    if (isAwaitingIdVerification(status)) {
        action = {
            <http://router.xyz|router.xyz>()
        }
    } else if (status == XYZ.PURCHASE) {
        action = {
            <http://router.xyz|router.xyz>()
        }
    }
    return action
}

When I run single unit test it complete fine, but when I run whole file unit test it failed.

We are at a disadvantage to help you diagnose a problem with the whole file, unless you share the whole file (as a text snippet, please). Usually in such scenarios there has been some stateful interaction between two or more tests. Unit Tests should always be as independent as possible.

The error message you get says "call 1 of 2" but you have only 1 call in your

verify

block. So you are probably looking at the wrong part of your code. Check the stack trace.

@darkmoon_uk I added my code when I run both code my first unit test fail and if run single then it pass the test case.

The failed test is called

com.abc.app.PlanHelperTest.getPendingStatusAction - WHEN is awaiting id verification, THEN returns action accordingly

. This is not one of the tests you've showed us.

Oh sorry I fixed the my unit test case description. It's same, I just added the description. Sorry about that.

This could be something related to Koin (perhaps the

router

used by

subject

is not the

mockRouter

) but as I don't know Koin, I can't help any further. Sorry about that.

Sure no problem @Klitos Kyriacou ✌️. thanks a million
