    @Test
    fun `should respond test`() {
        every { secondService.greet() } returns "test"
        assertThat(firstService.greet()).isEqualTo("test")
    }

    @Test
    fun `should respond second`() {
        every { secondService.greet() } returns "second"
        assertThat(firstService.greet()).isEqualTo("second")
        verify { secondService.greet() }
    }
