Am I doing this right? The

download

function seems to return, but before, it should return progress through the

SendChannel

(coroutines) passed to it... will that code do this?

I had a problem with mockk on gradle 5.0 . it is about ByteBuddyAgent dependency scope I think. Is it a known problem or should I create an issue for this?

How do I mock a public field in a Java class with a package local constructor, I need to pass it to another class's constructor...?

@oleksiyp, I may have missed this in the documentation, but are there any rules or best practices around when to use

over

returns

?

Anyone here used mockK to test their common code in #multiplatform project? I’m having an

Unresolved reference: mockK

error when I execute the test

Is it possible to verify code within a lambda is ran? With the following code:

fun getAllActiveWidgetsByPrice(db: DatabaseConnection): List<Widgets> = db.query {
    Widgets.select {
        Widgets.active eq true
    }.orderBy(Widget.price).map { toWidget(it) }
}

Could we verify that

Widgets.select

is called? Could we verify that we pass a lambda with

Widgets.active eq true

to

Widgets.select

? I feel like there is a way to do this, but I have not been able to get it to work.

@oleksiyp I want to contribute to the library but I don't know where to start. if you can give me some pointers I can try to help.

Hi folks, thanks for the awesome library 💪 I have a question, is it possible to mock a constructor invocation and thus return a mock? Something similar to powermock’s

PowerMockito.whenNew(RandomClass.class).withAnyArguments().thenReturn(myMock)

I am getting

io.mockk.MockKException: Missing calls inside every { ... } block.

while trying to mock staticString. is it a known problem?

This message was deleted.

Here is the test template, that I try to run.

Can you please report same to GH issue

Hey, @oleksiyp. I see that

ExpectSpec

is being used here. Please let us know if you believe that this is #kotlintest's fault 🙂

Is it possible to mock a Java static function, there doesn't seem to be any mention of this in the docs?

Does one you already succeed to mock Build.VERSION.SDK_INT ?

Hi guys. I trying to mock a method that returns coroutine

Job

But I get this runtime exception

java.lang.IllegalArgumentException: proxied interface methods have incompatible >return types:

public abstract boolean kotlinx.coroutines.Job.cancel()

public abstract void kotlinx.coroutines.Job.cancel()

at java.lang.reflect.Proxy.validateReturnTypes(Proxy.java:328)

Does confirmVerified works with Static mock ? I get “io.mockk.MockKException: can’t find stub class” exception when using it

hey so, I started using mockk and I got some really strange behaviour that simply comes from mockito-like stack-index-checking. Can I ask you guys why you went with mockito style DSL when kotlin has such nice method references? Using kotlin method references, you can ditch all of the scary not-thread-safe parameter/argument capturing in mockito and provide a pretty slick DSL:

fun usage(){
    val result2 = buildMock<java.lang.ProcessBuilder>{
        ProcessBuilder::inheritIO {
            TODO()
        }

        //one problem with method refs is that they are ambiguous when the method is overloaded
        // but inference takes care of that reasonably elegently
        oneArg(ProcessBuilder::directory).invokes {
            TODO()
        }
    }

I also think that using kotlin property references could make mocking of properties much nicer

Hi all, quick question: With MockK, how do I verify that a specific function of a mock was never called?

verify {
  mock.myFunction(any()) wasNot called
}

Doesn't seem to be correct as this is always true, regardless of whether the function was called or not.

I have another question 😉 Why is that

coEvery { view.showDeleteSectionDialog() } returns true

produces

Bad recording sequence. State: AnsweringState

but

with(view) {
    coEvery { showDeleteSectionDialog() } returns true
}

does not?

Is it possible to mock a suspend inline extension function? If so, how?

How can i reset the verify count?

verify(exactly = 1) { mView.showLocations(any()) }

// Reset verify

locationListPresenter.onFilterTextChanged(text)
verify(exactly = 1) { mView.showLocations(any()) }

i am with this isolationMode

IsolationMode.InstancePerLeaf

How to properly

mockk / verify

a lambda? Looks like

val observer = mockk<(Int) -> Unit>() 
observer( 1) 
verify { observer( 1 ) }

Is not working. Tbh I didn't test exactly that code, I was trying within an Android LiveData, but replacing the mockk with a real lambda i can see right output printed in the console. Same with

spy

hello guys, I try to mock/verify String.format(....)

the

GlobalScope.async { "testCarId" }

part seems weird to me I tried

returns  "testCarId"

but I'm getting an incompatible type error

it looks like it doesnt matter what I use as my tests passed on either of them. But I would like to know if I'm verifying the coroutine properly

Hi all! Could somebody please explain what this error means?

io.mockk.MockKException: Failed matching mocking signature for\n\nleft matchers: [any(), any(), any()]

Version 1.8.9 Code:

every { clientFactory.invoke(any(), any(), any()) } returns client

clientFactory

is factory function which returns the object of client.

I need some advice, I have lot of tests that uses

any()

as argument in the

every

part of my tests and then in the

verify

part I checked the exactly value of the argument like this

every { car.drive(any()) } returns Outcome.OK

verify(exactly = 1) {
    car.drive(Direction.SOUTH)
}

. I did this because it saves me a lot of typing (and maybe it makes the code more readable as it's shorter) when the argument I'm passing is too long for example: https://gist.github.com/rinnegan/bd8928a750fab4eaebf89652972c7647#file-using-any-L16. So it is okay to write my tests like this? Or do I need to avoid using

any()

and be very explicit and specify the exact argument?
