Unable to mock Map[String, String]

[diegoboston]

I'm using IdiomaticMockito in my test.

val mocked = mock[Map[String, String]]
mocked.apply(*) shouldReturn "123"
mocked("key") should equal("123")
mocked.apply(*) wasCalled once

This fails at run-time as shown below. A workaround is:

    abstract class TestMap extends Map[String, String]
    val mocked = mock[TestMap]

Note that the first example works fine with regular Mockito.

The failure:

                There was 1 failure:
                 1) initializationError(<MYTESTPATH>)
                 java.lang.StackOverflowError
                 	at ru.vyarus.java.generics.resolver.util.GenericsResolutionUtils.resolveGenerics(GenericsResolutionUtils.java:92)
                 	at ru.vyarus.java.generics.resolver.util.walk.TypesWalker.visitGenerics(TypesWalker.java:120)
                   ....

Interesting, the stack points to the lib I use to get more info about the generics, I’ll take a look over the weekend! That said, I’m not sure mocking a Map is something I’d recommend, it’s the kind of thing that would be better to just use a regular instance, what would it be the use case here?

Thanks. About my use case, I need a mock that returns "123" for every key.

In that case you can do something like val x = Map[String, String]().withDefault(“123”) Don’t have access to my computer right now, but that should do the trick

Yes, thanks so much, that would also work. Still, I'm curious to see if you can find the underlying bug. Mockito (Java) seems to be fine with this case.

Oh yes, I’ll definitely hunt that down

Wow, thanks for the quick fix!

[diegoboston]

Confirmed that the bug is fixed for me with version 1.14.1. Thanks so much.

No problem! Enjoy!
