8.7. 時間割アプリケーションの実行

手順

1. 以下の内容を含む src/test/java/com/example/rest/TimeTableResourceTest.java クラスを作成します。

   package com.exmaple.optaplanner.rest;
   
   import java.time.DayOfWeek;
   import java.time.LocalTime;
   import java.util.ArrayList;
   import java.util.List;
   
   import javax.inject.Inject;
   
   import io.quarkus.test.junit.QuarkusTest;
   import com.exmaple.optaplanner.domain.Room;
   import com.exmaple.optaplanner.domain.Timeslot;
   import com.exmaple.optaplanner.domain.Lesson;
   import com.exmaple.optaplanner.domain.TimeTable;
   import com.exmaple.optaplanner.rest.TimeTableResource;
   import org.junit.jupiter.api.Test;
   import org.junit.jupiter.api.Timeout;
   
   import static org.junit.jupiter.api.Assertions.assertFalse;
   import static org.junit.jupiter.api.Assertions.assertNotNull;
   import static org.junit.jupiter.api.Assertions.assertTrue;
   
   @QuarkusTest
   public class TimeTableResourceTest {
   
       @Inject
       TimeTableResource timeTableResource;
   
       @Test
       @Timeout(600_000)
       public void solve() {
           TimeTable problem = generateProblem();
           TimeTable solution = timeTableResource.solve(problem);
           assertFalse(solution.getLessonList().isEmpty());
           for (Lesson lesson : solution.getLessonList()) {
               assertNotNull(lesson.getTimeslot());
               assertNotNull(lesson.getRoom());
           }
           assertTrue(solution.getScore().isFeasible());
       }
   
       private TimeTable generateProblem() {
           List<Timeslot> timeslotList = new ArrayList<>();
           timeslotList.add(new Timeslot(DayOfWeek.MONDAY, LocalTime.of(8, 30), LocalTime.of(9, 30)));
           timeslotList.add(new Timeslot(DayOfWeek.MONDAY, LocalTime.of(9, 30), LocalTime.of(10, 30)));
           timeslotList.add(new Timeslot(DayOfWeek.MONDAY, LocalTime.of(10, 30), LocalTime.of(11, 30)));
           timeslotList.add(new Timeslot(DayOfWeek.MONDAY, LocalTime.of(13, 30), LocalTime.of(14, 30)));
           timeslotList.add(new Timeslot(DayOfWeek.MONDAY, LocalTime.of(14, 30), LocalTime.of(15, 30)));
   
           List<Room> roomList = new ArrayList<>();
           roomList.add(new Room("Room A"));
           roomList.add(new Room("Room B"));
           roomList.add(new Room("Room C"));
   
           List<Lesson> lessonList = new ArrayList<>();
           lessonList.add(new Lesson(101L, "Math", "B. May", "9th grade"));
           lessonList.add(new Lesson(102L, "Physics", "M. Curie", "9th grade"));
           lessonList.add(new Lesson(103L, "Geography", "M. Polo", "9th grade"));
           lessonList.add(new Lesson(104L, "English", "I. Jones", "9th grade"));
           lessonList.add(new Lesson(105L, "Spanish", "P. Cruz", "9th grade"));
   
           lessonList.add(new Lesson(201L, "Math", "B. May", "10th grade"));
           lessonList.add(new Lesson(202L, "Chemistry", "M. Curie", "10th grade"));
           lessonList.add(new Lesson(203L, "History", "I. Jones", "10th grade"));
           lessonList.add(new Lesson(204L, "English", "P. Cruz", "10th grade"));
           lessonList.add(new Lesson(205L, "French", "M. Curie", "10th grade"));
           return new TimeTable(timeslotList, roomList, lessonList);
       }
   
   }

   このテストは、解決後にすべての授業がタイムスロットと部屋に割り当てられていることを確認します。また、実行可能解 (ハード制約の違反なし) も確認します。

2. テストプロパティーを src / main / resources /application.properties ファイルに追加します。

   # The solver runs only for 5 seconds to avoid a HTTP timeout in this simple implementation.
   # It's recommended to run for at least 5 minutes ("5m") otherwise.
   quarkus.optaplanner.solver.termination.spent-limit=5s
   
   # Effectively disable this termination in favor of the best-score-limit
   %test.quarkus.optaplanner.solver.termination.spent-limit=1h
   %test.quarkus.optaplanner.solver.termination.best-score-limit=0hard/*soft
