我有一個使用 JMockit 進行單元測試的簡單實現。實現如下Team班級public class Team {    private TeamLeader teamLeader;    public Team(TeamLeader teamleader) {        this.teamLeader = teamleader;    }    public boolean hasDiscussion() {        System.out.println("Discussion is hold by " + teamLeader.getName());        Discussion discussion = new Discussion();        return discussion.start();    }}TeamLeader班級public class TeamLeader {    private String name;    public TeamLeader(String name) {        this.name = name;    }    public String getName() {        return name;    }}Discussion班級public class Discussion {    public boolean start() {        return false;    }}然后，我有一個單元測試來測試功能hasDiscussion如下@RunWith(JMockit.class)public class TeamTest {    private Team team;    @Test    public void hasDiscussion(@Mocked TeamLeader teamLeader, @Mocked Discussion discussion) {        new Expectations() {{            teamLeader.getName(); result = "teamleader";            discussion.start(); result = true;        }};        team = new Team(teamLeader);        boolean actualResult = team.hasDiscussion();        new Verifications() {{            assertThat(actualResult, is(true));        }};    }}執行測試時，出現以下錯誤Unexpected invocation of:entity.Discussion#Discussion()   on instance: entity.Discussion@7b70deb2when was expecting an invocation of:entity.Discussion#start()   on mock instance: [email protected]: Unexpected invocation of:entity.Discussion#Discussion()   on instance: entity.Discussion@7b70deb2when was expecting an invocation of:對這類問題有什么想法嗎？
