How mock a static method on a class

MockStatic.kt

@Test
fun `test fetchData with a different behaviour of UUID generation`() {
    val uuid = "my-fake-uuid"
    mockkObject(MyUselessUtils)
    every { MyUselessUtils.generateUUID() } returns uuid
    every { dataRepository.fetchData() } returns listOf(DataModel(1, "Value"))
    mainPresenter.fetchData()

    val captureData = slot<List<UiDataModel>>()

    verify(exactly = 1) { view.onResult(capture(captureData)) }
    captureData.captured.let { res ->
        assert(res.isNotEmpty())
        assertEquals(uuid, res.first().uuid)
    }
    unmockkObject(MyUselessUtils)
}
