The mock object records what happens, in the
verify we capture some parameters and inspect them in more detail.The confusing part is that this test captures callback functions, so they can be called in the test. But this is not really elegant, I will rework the code.
verify { foo.bar(withArg { it is MyClass }) } seems to work. Is this the way to go?
friends, i have a webFlux coRouter endpoints which has a kotlin muLogging statement. i would like to coVerify logger.info is executed in my Mockk unit-test case. any help would be appreciated. `fun myRouter() = coRouter {
val logger = KotlinLogging.logger {}
"/events".nest {
POST { req ->
val event = req.awaitBody<Event>()
logger.info { event }
ok().bodyValueAndAwait("")
}
}}`
Hi All,
I wanna ask about mocking android ViewModel.
I have a view model which having a few live data on it…
I tried to mock it by
val vm = mockk<CalibrationViewModel>(relaxed = true)
every { vm.getCalibrationId() } returns "mocked”on these getCalibrationId()
fun getCalibrationId(): String? {
return _calibrationId.value // <— private live data object
}but then I get an error like this:
Caused by: java.lang.IllegalAccessError: tried to access class androidx.lifecycle.LiveData$ObserverWrapper from class androidx.lifecycle.LiveData$Subclass0I thought that mockk will completely stub all the methods and properties without actually calling the real things….
any suggestions on this?
thanks in advance.
Another questions,
it seems to be hard to mock the viewModel with the issues above, so instead of mocking it, I tried to use the real object from the ViewModel.
val mockCalibration = CalibrationCreated(….)
fragment.viewModel = CalibrationViewModel(appContext).apply {
setPitchAngle(22.3f)
setRollAngle(33.3f)
setExistingCalibration(mockCalibration)
}
println(fragment.viewModel.getRollAngle()) // 33.3f
println(fragment.viewModel.getPitchAngle()) // 22.3f
println(fragment.viewModel.getExistingCalibration()) // null, should be not nullbut whenever I get these calibration from live data that hold its value, it always null…
here is the code inside these ViewModel
class CalibrationViewModel(application: Application) : AndroidViewModel(application) {
…
private val _existingCalibration = MutableLiveData<CalibrationCreated>()
fun setExistingCalibration(value: CalibrationCreated) {
_existingCalibration.postValue(value)
}
fun getExistingCalibration(): CalibrationCreated? {
return _existingCalibration.value
}
…
}any suggestion really appreciated.
Thanks in advance...

mockk-common fixed it
doWork method and having it do nothing
doWork and run it manually as part of your test, then you can capture the lambda with a slot and then run it manually in your test
hello folks :wave:
given the function:
fun <T : Any> myFunction(foo: Foo, bar: Bar, response: KClass<T>): MyResponse<T> { do magic }how can it be mocked to control the returned object?
I tried something like:
every { mockedClass.myFunction(any(), any(), ofType(SomeType::class) } returns SomeType()but it didn't work... and using the type directly, myFunction(any(), any(), SomeType::class) is never matched.
hey all — what's the best way to see if a function is being called with the right shape string? I have a function getRandomIdAndRunMethod and I want to verify that I'm calling method with the right shape random id
example code:
getRandomId() {
do server side stuff and return the id that (depending on other service) will be of shape xxxx-xxxx
}
method(id) {
sends an email to someone based on id
}
getRandomIdAndRunMethod() {}I'm trying to run this in a verify block and getting the error: No other calls allowed in stdObjectAnswer than equals/hashCode/toString
Hey have a problem by using a foreach loop of an object which is extending a Map. I try to setup my mocking like this
val tableMock = mockk<MyTable>(relaxed = true, name = "My table Mock")
val tableEntryMock = mockk<MyEntry>(relaxed = true, name = "My entry Mock")
every { tableMock[any()] } returns tableEntryMockBut in my foreach, where I'm iteration over MyTable nothing happen because its size is 0, obviously. So I try:
val tableMock = mockk<MyTable>(relaxed = true, name = "My table Mock")
val tableEntryMock = mockk<MyEntry>(relaxed = true, name = "My entry Mock")
val expectedMap = mutableMapOf<Int, MyEntry>(1 to tableEntryMock)
every { tableMock.iterator() } answers expectedMap.iterator()But the precompiler has a problem with my 'answers' :None of the following functions can be called with the arguments supplied.
answers(Answer<MutableIterator<MutableMap.MutableEntry<Int, MyTable>>>) defined in io.mockk.MockKStubScope
answers(MockKAnswerScope<MutableIterator<MutableMap.MutableEntry<Int, MyTable>>, MutableIterator<MutableMap.MutableEntry<Int, MyTable>>>.(Call) → MutableIterator<MutableMap.MutableEntry<Int, MyTable>>) defined in io.mockk.MockKStubScope
answerstakes a block, not a value
you should be doingevery { tableMock.iterator() } returns expectedMap.iterator()or
every { tableMock.iterator() } answers { expectedMap.iterator() }
Thanks to @Raibaz this doesn't solves the problem fully, but brings me one step forward (was using 'answers' wrong). Problem is a different type of the Iterators.
I'm trying to verify that a call was made. I'm using
verify (exactly =1) and there's no problem when passing in a normal string as an argument, but it's saying was not called when I use a list of strings as an argument. I've tried every combination of eq and similar that I can think of, but it's still insisting that the function hasn't been called when it definitely has. I thought it could be a reference vs value thing, but the eq thing negates that as an option. Any ideas?
was not called.
