How to verify a method gets called with an object whose some fields may be anyObject() while others have a...
I'm using Mockito with ScalaTest. Consider this simplified example.
Model case class:
case class Batch(batchId: Long,
timestamp: Option[LocalDateTime] = Some(LocalDateTime.now),
invoicesReceived: Option[Int])
In my test I'm mocking a class called BatchRepository which has a method with this signature:
def create(conn: Connection, batch: Batch): Long
Relevant bit of test code:
verify(batchRepository, times(1)).create(anyObject(),
Batch(anyLong(), anyObject(), Matchers.eq(Some(1))))
)
The beef is: I'd like to verify that the code under test calls the mocked repository method with whatever Connection and a Batch instance with whatever id and timestamp, but invoicesReceived being exactly Some(1).
Using Mockito, is this possible at all, and if so, how?
The production code creates a new Batch which sets the timestamp to current moment, so I think it's pretty much impossible to create a real Batch object in the test for the verify() call with the exact same timestamp. So at least for the timestamp I'd need anyObject().
I tried many variations, like wrapping the whole Batch in Matchers.eq(), but I haven't found anything that works:
Invalid use of argument matchers! 2 matchers expected, 4 recorded [...]
I'd be happy to hear I'm using matchers all wrong if there turns out to be some alternative way to use Mockito to test what I want. 🙂
(I was having hard time writing a good name for this question; please edit or leave a comment if you understand what I'm asking and can express it more succinctly.)

The problem is you are trying to verify two calls at once - create and Batch.apply. Can't do that.
One way to do what you want is ArgumentCaptor:
val captor = ArgumentCaptor.forClass(classOf[Batch])
verify(batchRepository).create(any(), captor.capture)
captor.getValue should matchPattern {
case Batch(_, _, Some(1)) =>
}
// or just `captor.getValue.infoReceived shouldBe Some(1)`

Awesome, thanks! I was usingFunSuitesoshould matchPatterndoesn't seem to be available butcaptor.getValue matchand thencase _ => failseems clean enough.

Why do you keep reverting the answer toanywhich does not compile in my case? Wouldn't it be more useful to have a version that will actually work as-is for me and future readers? (anyproduces "polymorphic expression cannot be instantiated to expected type";any()works.)

Just mix inMatchersto get thematchPatternto work. As foranywithout parens, I guess, you are right ... Turns out I just have a workaround in my codebase:def any[T] = Matchers.any()for so long, that I forgot about it :) I was reverting it because I don't appreciate people editing my stuff without asking first.

verify(batchRepository, times(1)).create(any, argMatching({case Batch(_, _, Some(1)) => }))
Or even better if you use the idiomatic syntax
batchRepository.create(*, argMatching({case Batch(_, _, Some(1)) => })) was called

Have you tried mockito-scala? it supports partial functions as matchers so you could just write
verify(batchRepository, times(1)).create(any, argMatching({case Batch(_, _, Some(1)) => }))
Or even better if you use the idiomatic syntax
batchRepository.create(*, argMatching({case Batch(_, _, Some(1)) => })) was called
