/serverpod:test — 백엔드 자동 검사지 만들기#

Serverpod 백엔드(서버 쪽 코드)가 제대로 작동하는지 확인하는 "자동 검사지(테스트 코드)"를 대신 작성해 주는 도우미입니다.

한마디로#

새로 만든 서버 기능이 의도대로 동작하는지 매번 손으로 확인하지 않아도 되게, 자동으로 돌려보는 검사지(테스트 코드) 를 만들어 줍니다. 새 제품을 출고하기 전에 품질 검사 체크리스트를 자동으로 작성해 주는 것과 같아요.

누가·언제 쓰나요#

서버에 새 기능(엔드포인트)을 만든 뒤, 그게 잘 돌아가는지 검증하는 테스트가 필요할 때
/feature:create(전체 기능 만들기) 과정 3단계에서 자동으로 호출됩니다
로그인이 필요한 기능, 관리자만 쓸 수 있는 기능이 제대로 막혀 있는지 확인하고 싶을 때

무엇을 해주나요#

테스트 코드 파일을 자동으로 만들어 줍니다. 실제로 생기는 파일은:

backend/kobic_server/test/integration/{기능이름}_endpoint_test.dart — 통합 테스트 (실제 서버를 띄워 전체 흐름 확인)
backend/kobic_server/test/unit/{기능이름}/{기능이름}_service_test.dart — 단위 테스트 (개별 로직 확인)

검사지에는 보통 이런 항목이 담깁니다: 로그인 없이 호출하면 막히는지, 권한 없는 사용자는 거부되는지, 만들기·읽기·수정·삭제(CRUD)가 정상 동작하는지, 잘못된 값을 넣으면 오류가 나는지 등.

어떻게 쓰나요#

# 기본 (통합 테스트 생성)
/serverpod:test

# 같은 기능을 하는 다른 호출 이름(별칭)
/backend:test
/api:test

테스트 종류는 integration(통합), unit(단위), both(둘 다) 중에서 고를 수 있고, 별도로 지정하지 않으면 통합 테스트가 만들어집니다.

만들어진 테스트를 실제로 돌려볼 때는:

# 통합 테스트만 실행
cd backend/kobic_server
dart test test/integration/

# 전체 테스트 실행
dart test

안에서 무슨 일이 벌어지나요#

새로 만든 서버 기능(엔드포인트) 코드를 살펴보고, 어떤 항목을 검사해야 할지 정리합니다.
로그인이 필요한 기능이면 "로그인 안 하면 막히는지" 검사를 추가합니다.
관리자 권한이 필요한 기능이면 "일반 사용자는 거부되는지" 검사를 추가합니다.
만들기·읽기·수정·삭제(CRUD)가 제대로 되는지, 잘못된 입력에 오류가 나는지 검사를 더합니다.
이 모든 항목을 하나의 테스트 파일로 만들어 줍니다.

Import Order (Required)#

// 1. Test framework
import 'package:test/test.dart';

// 2. Generated protocol (models) - if needed
import 'package:kobic_server/src/generated/protocol.dart';

// 3. Test tools (auto-generated)
import 'test_tools/serverpod_test_tools.dart';

Core Patterns#

1. Integration Test Basic Structure#

import 'package:test/test.dart';
import 'package:kobic_server/src/generated/protocol.dart';
import 'test_tools/serverpod_test_tools.dart';

void main() {
  withServerpod('Given {Feature} endpoint', (sessionBuilder, endpoints) {
    // Test groups...
  });
}

2. Unauthenticated Call Test#

group('Authentication required tests', () {
  test('Throws ServerpodUnauthenticatedException when called without auth', () {
    expect(
      () => endpoints.{feature}.{method}(sessionBuilder),
      throwsA(isA<ServerpodUnauthenticatedException>()),
    );
  });
});

3. Authenticated User Test#

group('Authenticated user tests', () {
  late TestSessionBuilder authenticatedBuilder;

  setUp(() {
    authenticatedBuilder = sessionBuilder.copyWith(
      authentication: AuthenticationOverride.authenticationInfo(
        '1', // userId
        {}, // scopes (empty Set: regular user)
      ),
    );
  });

  test('{Entity} creation succeeds', () async {
    // Arrange
    final request = Create{Entity}Request(
      title: 'Test Title',
      description: 'Test Description',
    );

    // Act
    final result = await endpoints.{feature}.create{Entity}(
      authenticatedBuilder,
      request,
    );

    // Assert
    expect(result.id, isNotNull);
    expect(result.title, equals('Test Title'));
  });
});

4. Admin Permission Test (Console Endpoint)#

group('Admin permission tests', () {
  late TestSessionBuilder adminBuilder;

  setUp(() {
    adminBuilder = sessionBuilder.copyWith(
      authentication: AuthenticationOverride.authenticationInfo(
        '1', // userId
        {Scope.admin}, // Admin scope
      ),
    );
  });

  test('List {Entity}s as admin succeeds', () async {
    // Arrange
    const limit = 10;
    const offset = 0;

    // Act
    final result = await endpoints.{feature}Console.get{Entities}(
      adminBuilder,
      limit: limit,
      offset: offset,
    );

    // Assert
    expect(result, isA<List<{Entity}>>());
  });

  test('Regular user calling admin API throws permission error', () {
    final userBuilder = sessionBuilder.copyWith(
      authentication: AuthenticationOverride.authenticationInfo('1', {}),
    );

    expect(
      () => endpoints.{feature}Console.get{Entities}(
        userBuilder,
        limit: 10,
        offset: 0,
      ),
      throwsA(isA<ServerpodInsufficientAccessException>()),
    );
  });
});

5. Error Case Tests#

group('Error cases', () {
  late TestSessionBuilder authenticatedBuilder;

  setUp(() {
    authenticatedBuilder = sessionBuilder.copyWith(
      authentication: AuthenticationOverride.authenticationInfo('1', {}),
    );
  });

  test('Throws NotFoundException when querying non-existent ID', () {
    expect(
      () => endpoints.{feature}.get{Entity}(
        authenticatedBuilder,
        99999, // Non-existent ID
      ),
      throwsA(isA<{Feature}NotFoundException>()),
    );
  });

  test('Throws ValidationException with invalid parameters', () {
    expect(
      () => endpoints.{feature}.get{Entities}(
        authenticatedBuilder,
        limit: -1, // Invalid value
        offset: 0,
      ),
      throwsA(isA<Invalid{Feature}ParameterException>()),
    );
  });
});

6. Full CRUD Test (Create → Read → Update → Delete)#

group('Full CRUD flow', () {
  late TestSessionBuilder adminBuilder;

  setUp(() {
    adminBuilder = sessionBuilder.copyWith(
      authentication: AuthenticationOverride.authenticationInfo('1', {
        Scope.admin,
      }),
    );
  });

  test('Create → Read → Update → Delete full flow', () async {
    // 1. Create
    final created = await endpoints.{feature}Console.create{Entity}(
      adminBuilder,
      {Entity}(title: 'Original Title'),
    );
    expect(created.id, isNotNull);

    // 2. Read
    final fetched = await endpoints.{feature}.get{Entity}(
      adminBuilder,
      created.id!,
    );
    expect(fetched.title, equals('Original Title'));

    // 3. Update
    final updated = await endpoints.{feature}Console.update{Entity}(
      adminBuilder,
      created.id!,
      {Entity}UpdateRequest(title: 'Updated Title'),
    );
    expect(updated.title, equals('Updated Title'));

    // 4. Delete
    final deleted = await endpoints.{feature}Console.delete{Entity}(
      adminBuilder,
      created.id!,
    );
    expect(deleted, isTrue);

    // 5. Verify deletion
    expect(
      () => endpoints.{feature}.get{Entity}(adminBuilder, created.id!),
      throwsA(isA<{Feature}NotFoundException>()),
    );
  });
});

Unit Test Pattern#

Service Logic Test#

import 'package:test/test.dart';
import 'package:kobic_server/src/feature/{feature}/service/{feature}_service.dart';
import '../integration/test_tools/serverpod_test_tools.dart';

void main() {
  withServerpod('Given {Feature}Service', (sessionBuilder, _) {
    test('Business logic validation', () async {
      // Arrange
      final session = await sessionBuilder.build();

      // Act
      final result = await {Feature}Service.someBusinessLogic(
        session,
        param1: 'value1',
      );

      // Assert
      expect(result, isNotNull);
    });
  });
}

Test Execution Commands#

Serverpod 4 local full-stack note: With Serverpod 4 (tech preview), the bundled embedded Postgres lets integration tests run fully locally without Docker. Run serverpod start (which boots the backend server + embedded Postgres + Flutter app with sub-second hot reload), then run dart test test/integration/ (or dart test -t integration) directly. No docker compose up -d needed. See serverpod-local-fullstack. The docker compose up -d path below is preserved as the v3 / legacy flow (kobic production is on 3.x).

# (3.x / legacy) Start Docker (PostgreSQL, Redis required)
docker compose up -d

# Run integration tests only
cd backend/kobic_server
dart test test/integration/

# Run specific file
dart test test/integration/{feature}_endpoint_test.dart

# Run all tests
dart test

# Test coverage
dart test --coverage=coverage
