Minimal reproducible code (the gist of this issue)
class MockCls {
fun add(a: Int, b: Int) = a + b
companion object {
const val VALUE = 5
}
}
@Test
fun testMockkConstructor() {
mockkConstructor(MockCls::class)
every { anyConstructed<MockCls>().add(1, 2) } returns 4
assertEquals(4, MockCls().add(1, 2))
}
