Mockk: Using @JvmStatic annotation makes Mockk to throw an exception

[VictorAlbertos]

First I want to thank you for this amazing library, as far as I know it's the only mock framework made purely with Kotlin.

Now the bad news :D

If an Object has one of its methods annotated with @JvmStatic, when trying to mock that method, an exception is thrown.

Code to reproduce the bug

object ObjectAnnotated {
    @JvmStatic fun foo() = "foo"
}

class ObjectAnnotatedTest {
    @Test
    fun verifyFoo() {
        objectMockk(ObjectAnnotated).mock()
        every { ObjectAnnotated.foo() } returns "bar"
        assert(ObjectAnnotated.foo() == "bar")
    }
}

Stacktrace

io.mockk.MockKException: Missing calls inside every { ... } block.

I'm using latest version -> 1.8

Please let me know if you need further support.

Just try static mock on that object class

[VictorAlbertos]

I don't know what you mean by static mock. Can you share the implementation based on my previous example?

[oleksiyp]

Can't check right now this code(hope it works):

class ObjectAnnotatedTest {
    @Test
    fun verifyFoo() {
        staticMockk<ObjectAnnotated>().use {
            every { ObjectAnnotated.foo() } returns "bar"
            assert(ObjectAnnotated.foo() == "bar")
       }
    }
}

It works, thanks @oleksiyp for the support 👍
