안녕하세요 강사님

Question

테스트 관련 강의를 보다가

OutputCapture를 테스트 해보려고헀는데 하기와 같은 에러가 발생해서 질문드리고싶습니다..

    }

    //@Test
    public void Test3() throws Exception{
        when(sampleService.getName()).thenReturn("heesuk");

        String result = testRestTemplate.getForObject("/hello",String.class);
        assertThat(result).isEqualTo("hello heesuk");
    }

    @Test
    public void Test4() throws Exception{
        when(sampleService.getName()).thenReturn("heesuk");

        webTestClient.get().uri("/hello").exchange()
                .expectStatus().isOk()
                .expectBody(String.class).isEqualTo("hello heesuk");

        assertThat(outputCapture.toString())
                .contains("holoman")
                .contains("skip");
    }
}

OutputCapture가 - 표시가 되어있어서 OutputCaptureRule을 사용헀더니 하기와 같은 에러가 나옵니다.
