I have a question if I have an attachView and detachView on my Presenter do I have to test these methods? Inside of the presenter I have the loadData and I have the unit tests for this loadData but then I have these methods and I don't know if I have to unit test those or not
And then I have a repository that does this

class CryptoListRepositoryImpl(var cryptoCurrencyService: CryptoCurrencyService) : CryptoListRepository {
    override fun getResultData(): Single<CryptoResponse> {
        return cryptoCurrencyService.getCryptoCurrency()
    }
}

do I have to unit test this getResultData() ? (edited)
And then an use case

class GetCryptoListUseCase @Inject constructor(var cryptoListRepository: CryptoListRepository) {
    fun execute(): Single<List<CryptoViewModel>> {
        return cryptoListRepository.getResultData().map {
            cryptoCurrencyMapper(
                it
            )
        }
    }
}

I have to Unit test the mapper and the use case execute()?

It’s definitely an opinion - but if it were me, as long as I had an acceptance test somewhere covering this flow, I definitely wouldn’t unit test the code you’ve presented

You didn’t show your cryptoCurrencyMapper so I can’t comment on that

[Joan Colmenero]

No because I know I have to, I mean I did a test for the mapper, but my real question is, do I have to test the view stuff? I mean showProgressBar, attachView, dettachView, etc..?
