Overview

Hello,
I have an issue when I try to stub a method with a callback.
When I execute the code bellow the callback data are not populated on my mockOnboardingRepository

Example

given(mockOnboardingRepository.getOnboardingData(any())).will { (callback: ([OnboardingModel]) -> Void) in callback([OnboardingModel.init(picture: R.image.onboarding1, title: "", subtitle: "", isLast: false)]) }

verify(mockOnboardingRepository.getOnboardingData(any())).wasCalled() --> OK

expectation.fulfill() XCTAssertEqual(sut.output.allData.value.count, 1) --> No Data on my result array

Expected Behavior

I want to have the data on my repository
