QUESTION
I am trying to get the second last value in each row of a data frame, meaning the first job a person has had. (Job1_latest is the most recent job and people had a different number of jobs in the past and I want to get the first one). I managed to get the last value per row with the code below:
first_job <- function(x) tail(x[!is.na(x)], 1)

QUESTION
I am running into this issue in a somewhat larger context, but when condensed to the bare minimum, the question that remains is why does Moq not return the type specified in the interface for mocked methods? IEnumerable and List come back as empty arrays, When I specifically call Setup with a return value, it changes, at least in the example below.

QUESTION
Im trying to verify whether my code is printing in Kotlin or logging out the right Log in Android. With other function it is ok for me but for these kind of function can anyone show me how to do it.
...ANSWER
Answered 2021-Feb-04 at 08:22You can try something like mockkStatic(Class.forName("kotlin.io.ConsoleKt")::class)
, but it's impossible
Even the print function used inside the mockk becomes a mockk, causing StackOverflow.

QUESTION
From this Difference between @Mock and @InjectMocks I understand that @InjectMocks is used as an annotation for create an instance and inject the mocks that are created with @Mock into it. I don't think I understand how it works.
I have an example code on which I would like to ask you 2 questions in order to go straight to the points that are not clear to me. The questions are at the end.
I have an interface:
...ANSWER
Answered 2021-Jan-07 at 20:42- Qn why mockedAppointments.keySet() doesn't throw a nullPointerException (mockedAppointments is only declared)? maybe because it's a mock? And if the reason is this, why doesn't a mock throw "nullPointerException"?
Answer is : BecausemockedAppointments.keySet().size
is 0 andmockedAppointments.keySet()
is empty, it is the behavior of the mock - 2.0 Qn System.out.println(this.appointments == null); line prints "false" is i keep the @InjectMocks annotation, "true" otherwise, but why?
Answer is : In junit or mockito System.out.println won't works, rather use logger.
2.1 Qn In the first case (@InjectMocks is kept) where is the "appointments" attribute of "agenda" initialized?
Answer is : it is mocking the class and eg for list it initialize as 0 and keep value as empty, Inaddition to that

QUESTION
I have been looking for ways to exclude an individual test from @BeforeEach. It was suggested to me in my previous question to use TestInfo Interface: Can I exclude an individual test from @BeforeEach in JUnit5?
I am very interested in this kind of solution. However I tried that and it did not work for me. Is it possible to do it that way? Am I doing anything wrong in my code?
...ANSWER
Answered 2019-Nov-11 at 09:57Seems like a hack-approach to attempt individual exclusion. Why not use @Nested?
