Controller Test 시 @WebMvcTest 사용 관련 질문입니다.

미해결

호돌맨의 요절복통 개발쇼 (SpringBoot, Vue.JS, AWS)

안녕하세요 호돌맨님 :) 좋은 강의 늘 감사드립니다. Controller Test 할 때 질문이 있습니다. 강의에서 호돌맨님께서는 @SpringBootTest 사용하셨는데 저는 한 번 @WebMvcTest를 사용해보고 있습니다. 그러다보니 문제가 하나 발생을 하더라구요. 우선 PostController 쪽 코드를 보여드리겠습니다. @GetMapping("/posts") public ApiResponse<List<PostResponse>> getAll(@ModelAttribute PostSearch postSearch) { List<PostResponse> posts = postService.getAllPost(postSearch); return ApiResponse.ok(posts); } 보시면 게시글을 전체 조회하는 이 메서드의 경우에는 인증이 따로 필요없이 바로 조회가 되게 했는데요. Insomnia 라는 프로그램을 통해서 테스트했을 때 따로 인증하지 않아도 전체 조회 요청이 성공하는 것을 확인했습니다. 그런데 테스트코드를 작성할 때 인증 처리를 해주지 않으면 계속해서 401 에러가 발생을 하더라구요. @DisplayName("게시글을 전체 조회한다.") @CustomMockUser //todo 실제로는 인증이 필요없는데도 테스트 통과를 위해서 인증 처리를 해줘야 하는 것인가? @Test void getAllPosts() throws Exception { // given List<Post> posts = IntStream .range(1, 5) .mapToObj(i -> Post.of(FREE, i + "번 제목입니다.", i + "번 내용입니다.")) .toList(); List<PostResponse> response = changePostListToPostResponseList(posts); // when when(postService.getAllPost(any())).thenReturn(response); //then mockMvc.perform( MockMvcRequestBuilders.get("/api/posts") ) .andDo(MockMvcResultHandlers.print()) .andExpect(MockMvcResultMatchers.jsonPath("$.code").value(200)) .andExpect(MockMvcResultMatchers.jsonPath("$.message").value("OK")) .andExpect(MockMvcResultMatchers.jsonPath("$.status").value("OK")) .andExpect(MockMvcResultMatchers.jsonPath("$.data").isArray()) .andExpect(MockMvcResultMatchers.status().isOk()); } @CustomMockUser 어노테이션을 붙여줘야 테스트 통과가 되는 상황입니다. 실제 원하는 기능은 인증없이 전체 조회 되게 하는 것이 목표인데 테스트 통과를 위해서 @CustomMockUser 어노테이션을 붙여주는 것이 올바른 테스트인지 궁금합니다! 혹시 이게 @WebMvcTest와 관련없는 다른 문제라면 알려주시면 한 번 제가 더 찾아보겠습니다..!

함수의 공변성과 반공변성에 대한 이유 설명

미해결

[리뉴얼] 타입스크립트 올인원 : Part1. 기본 문법편

질문은 아니지만 다른 분들도 쉽게 보시고 이해하실 수 있도록 해당 수업의 질문으로 남기도록 하겠습니다. 설명에 앞서 그냥 강사님께서 하신 말씀처럼 외우는게 제일 나을수도 있습니다. 그냥 저처럼 이해하지 못하면 못 넘어가는 사람들을 위해 남깁니다. 공변성과 반공변성에 대하여 매개변수와 리턴타입의 대입가능성에 대해 설명하고자 합니다. 강의에서 사용된 예제를 사용하겠습니다. function a(x: string | number): number{ return 0; } type B = (x: string) => number | string; let b: B = a; b("asdf") // B타입에 맞음 정상 b(123) //B타입에 맞지 않는 매개변수 이므로 //typescript가 오류를 잡아줄 수 있음 먼저 매개변수에 대한 이야기입니다. 변수 b의 B 타입으로 정의되었습니다. 즉, 매개변수로는 x: string만 오도록 강제할 것입니다. 이는 b("asdf") 로 사용했을 때 a("asdf") 를 사용한 것과 같은 상황이니 문제가 없습니다 . 하지만 반대면 어떨까요? function a(x: string): number{ return 0; } type B = (x: string | number) => number | string; let b: B = a; b("asdf") // 타입 B에 대해서도 정상 //a함수가 실행될때도 정상 b(123); // B타입상으로만 보면 정상임 //그러나 실제로 a함수가 실행될 때 오류 //따라서 이런 상황이 발생하지 않도록 //타입스크립트는 타입B에 함수 a를 할당할 수 없도록 함 만약 이 상황이라면 변수 b는 B타입이기 때문에 매개변수로 number도 사용하능 합니다. 즉 타입상으로는 b(123) 이 가능하다는 것이죠, 하지만 이 경우 a(123) 이 실행되는 것과 같은데 a의 매개변수로는 string만 가능하기 때문에 문제가 발생합니다. 정리하자면 실제로 대입된 함수의 매개변수가 허용하지 않는 타입을 넣으면 안 되기 때문에, (대입되는 함수의 매개변수)는 (타입의 매개변수)와 같거나 더 넓어야합니다. 리턴값도 비슷한 원리입니다. function a(x: string | number): number{ return 0; } type B = (x: string) => number | string; let b: B = a; let result = b("asdf"); //result의 타입은 B타입에 의해 number|string 으로 추론됨 //실행결과 실제 타입은 number로 추론과 일치 타입스크립트 입장에서 b("asdf") 의 예상 결과는 number | string 이겠죠. b는 타입 B 니까요. 그리고 실제로 b("asdf") 는 실제로 a("asdf") 를 실행하는 것과 같으니 실제로는 number 가 리턴됩니다. 타입스크립트는 number | string 를 예상하고 있고, 거기에 number 가 온 것이니 문제가 없습니다. 반대 상황을 봅시다. function a(x: string | number): number | string { return 0; } type B = (x: string) => number; let b: B = a; let result = b("asdf"); //타입 B만 보고 추론하면 result는 number임 //근데 실제 실행결과로 result는 string이 될 수도 있음 타입스크립트는 b("asdf") 의 결과로 number 만을 기대할 것입니다. 근데 실제로 a("asdf") 는 number | string 이에요. 그러면 원래는 b의 실행결과로는 number 만 예상하고 있었는데 실제 결과로 number | string 이면 문제가 있겠죠? 정리하자면 실제로 대입된 함수가 리턴한 값이 타입의 리턴값에 포함되지 않으면 안 되기 때문에, (대입되는 함수의 리턴값)는 (타입의 리턴값)와 같거나 더 좁아야합니다. 위 모든 원칙은, 타입스크립트가 실제로 대입된 함수의 타입은 신경쓰지 않고, 현재 정의된 타입이 뭔지만 신경쓰기 위해서 존재한다고 생각하시면 이해가 편하실수도 있을 것 같네요... 타입스크립트의 타입검사기 입장에서 let b: B = a; 이후에 b를 쓸 때, a에 대해서 신경1도 안쓰고 B에 대해서만 타입 검사를 해주려고 처음 대입할때 매개변수의 범위와 리턴값의 범위를 저렇게 제한했다고 보시면 된다는 뜻입니다.

1강-문자(배)열 상수는 어디에 저장되는가? 관련 질문

해결됨

독하게 되새기는 C 프로그래밍

5번째 줄에 있는 문자열과, 7번째 줄에 있는 문자열은, 같은 문자열입니다.(당연히 같은 메모리 공간에 존재) 이 부분에서 궁금한 점이 생겨 질문을 하게 되었습니다. 다른 문자열로 일일이 메모리에 저장하지 않고, 굳이 같은 문자열로 저장하는 이유가 있을까요?(제 추측으로는 속도 향상을 위해서 같습니다. 하지만 개발자가 같은 메모리에 위치한다는 사실을 잘 인지하지 못한다면 오류도 빈번히 발생할 것 같은데 이유가 궁금합니다.) 같은 문자열이 아닌 다른 문자열로, 즉 다른 메모리 공간에 각각 존재시키고 싶다면, 어떻게 해야할까요? 1번에서 '개발자가 같은 메모리에 위치한다는 사실을 잘 인지하지 못한다면 오류도 빈번히 발생할 것 같은데' 라고 제가 추측했었습니다. 실제로 이러한 예시가 있는지 궁금합니다.

PCA 및 SVD 범주형 변수

미해결

PCA나 SVD를 통해서 차원축소를 할때, 이 두 방법은 모두 수치형변수를 기본으로 하여 차원축소하는 법이라고 알고있습니다. 혹시 데이터에 범주형변수가 있을때, 이는 어떻게 처리하는 것이 좋을까요? 원핫인코딩 혹은 레이블 인코딩 범주형 컬럼 제외하기 등 의 방법이 있을 것이라고 예상되는데, 1번으로 했더니 explained variance ratios가 현저하게 낮아져서 2번방법이 그나마 나을 것이라고 생각되는데, 범주형변수가 있는 경우에 pca나 svd를 보통 어떻게 적용하나요?

(ㅠㅠ) 저는 Ubuntu-22.04.2 버전을 사용했을 때 안됐고, 20.04.6 버전 사용했더니 이제야 설치가 잘 됐네요. 영상에서는 22.04.5 도 잘 설치가 된다고 하셨는데, 뭐가 문제인지는 잘 모르겠습니다. 설치가 돼서 너무 기쁘네요!!! 드디어 강의 들으러 갑니다 ㅎㅎ

안녕하세요. 플래그에 대해서 궁금해져서 질문드립니다.

해결됨

개발자를 위한 컴퓨터공학 1: 혼자 공부하는 컴퓨터구조 + 운영체제

제가 깊게 몰라서 이런 질문 드리는 것일지 모르겠지만 CPU 자체에 음수와 양수를 구분하기 위한 플래그가 있다면 굳이 2의 보수법으로 음수를 표현하기 보다는 그냥 그 수 자체에 음수라는 플래그를 달아서 단순히 표현하는 것이 더 낫지 않나요? 예를 들어서 0101(2) 가 플래그를 음수로 달고있으면 -5라고 바로 인식할 수 있는 것인데 괜히 복잡하게 2의 보수법을 사용해서 0101(2)가 플래그를 음수로 달고 0101(2)라는 것을 또 1011(2)의 음수로 인식을 해서 CPU가 일을 두 번 하게 만드는 것이 아닌가 해서 여쭤봅니다.

1. One of the easiest things to check is growth, both because it's easy to measure and because most companies (Yammer included) track this closely already. In this case, you have to make it yourself, though. You'll notice that nothing has really changed about the growth rate—it continues to be high during the week, low on weekends: View Mode Analysis 이 부분에서 쿼리를 SELECT DATE(created_at) AS day, COUNT(*) AS all_users, SUM(CASE WHEN activated_at IS NOT NULL THEN 1 ELSE 0 END) AS activated_users FROM tutorial.yammer_users WHERE created_at >= '2014-06-01' AND created_at < '2014-09-01' GROUP BY DATE(created_at) ORDER BY DATE(created_at); 이런 식으로 작성했던데, 당일 활동 유무가 위의 growth에 어떤 점을 알려 줄 수 있는건가요? 가입자의 패턴와 가입한 날의 활동 유무의 패턴이 비슷하다는 걸 알려주는건가요? 근데 당일 가입자의 당일 활동 유무가 어떤 의미있는 패턴을 알려줄 수 있는 걸까요?

게임 프로그래머 취업 전략 가이드

지난주부터 언리얼5로 VR 퍼즐게임 포트폴리오를 만드는 중입니다. 발사한 레이저를 거울 배치를 통해 특정지점으로 유도하기 전선 이어서 문 스위치 켜기 망치로 플레이트를 뒤집어서 특정 모양 만들기 등의 기믹을 만들려고 하고 있습니다. 그런데 한국 게임회사서는 VR게임을 시도를 거의 하지 않고 있고 신규 프로젝트 계획도 적은 걸로 아는데 취업을 위해 이렇게 만들어도 될지 의문이 듭니다. 저도 MMO, FPS를 좋아하고 오래 했기 때문에 이러한 팀에 들어가고 싶긴 합니다. 이런 팀에 지원하는데 VR게임 포트폴리오를 내미는 건 리스크가 있는 선택일까요? 아니면 인터렉션 구현을 잘했다면 좋은 평가를 받을 수 있을까요? 블루프린트 에셋을 C++로 옮겨서 만들어 쓴 부분도 좋은 평가를 받을 수 있는 부분일까요? 지금이라도 PC FPS나 TPS를 만들어야 하나 고민입니다.
