参数化测试因 mvn 测试而失败

Parameterized tests fail with mvn test

我在一个简单的参数化 java 测试中苦苦挣扎,找不到合适的解决方案:-S

也许你可以给我一个提示,我错过了什么。

以下场景我一直在测试 运行

当我在 class RoundDefinition 中复制完全生成的 hashCode 方法时,它工作得很好。但是我不想用生成的方法明确地覆盖 hashCode 方法...(这显然不是解决方案)

型号

@Entity
@Data
@Table( name = "tbl_rounddefinition" )
@JsonIgnoreProperties( value = { "hibernateLazyInitializer", "handler", }, ignoreUnknown = true )
@ToString( exclude = { "tournament" } )
@EqualsAndHashCode( exclude = { "tournament" } )
public class RoundDefinition implements Serializable {

    @Id
    @GeneratedValue( strategy = IDENTITY )
    @Column( name = "rounddefinition_id" )
    private Long id;

    @ManyToOne( fetch = FetchType.LAZY )
    @JoinColumn( name = "rounddefinition_linktournamentid" )
    @JsonIdentityInfo( generator = ObjectIdGenerators.PropertyGenerator.class, property = "id" )
    @JsonIdentityReference( alwaysAsId = true )
    private Tournament tournament;

    @Column( name = "rounddefinition_round" )
    private Integer round;

    @Column( name = "rounddefinition_numberOfRoundresults" )
    private Integer numberOfRoundresults;
}
@Data
@ToString( exclude = { [...] } )
@EqualsAndHashCode( exclude = { [...], "roundDefinitions" } )
@Entity
@Table( name = "tbl_tournament" )
@JsonIgnoreProperties( value = { "hibernateLazyInitializer", "handler" }, ignoreUnknown = true )
public class Tournament implements Serializable {

[...]

    @OneToMany( fetch = FetchType.LAZY, mappedBy = "tournament", cascade = CascadeType.ALL, orphanRemoval = true )
    @JsonSerialize( using = CollectionSerializer.class )
    @JsonDeserialize( using = CollectionDeserializer.class )
    @OrderBy( " round ASC " )
    private Set<RoundDefinition> roundDefinitions = new HashSet<>();

[...]

}

lombok 生成的代码

public int hashCode() {
        int PRIME = true;
        int result = 1;
        Object $id = this.getId();
        int result = result * 59 + ($id == null ? 43 : $id.hashCode());
        Object $round = this.getRound();
        result = result * 59 + ($round == null ? 43 : $round.hashCode());
        Object $numberOfRoundresults = this.getNumberOfRoundresults();
        result = result * 59 + ($numberOfRoundresults == null ? 43 : $numberOfRoundresults.hashCode());
        return result;
    }

切换到显式生成

Set<RoundDefinition> definitions = new HashSet<>(  );
        for (RoundDefinition rd : roundDefinitions) {
            RoundDefinition asd = new RoundDefinition();
            asd.setRound( rd.getRound() );
            asd.setNumberOfRoundresults( rd.getNumberOfRoundresults() );
            definitions.add(asd); // <-- ArrayIndexOutOfBoundsException
        }

#3 编辑:

出于好奇,我尝试将一个元素添加到另一组 class

Set<Tournament> tournamentSet = new HashSet<>();
tournamentSet.add(new Tournament()); <-- ArrayIndexOutOfBoundsException

还将这样的初始化添加到其他测试中...相同的行为o.O 但是我可以将字符串添加到 HashSet<String>... 这到底是怎么回事 :-D

#4 编辑:

已检查更改的依赖项,但它们似乎与源代码分支相同。也可在源代码分支中重现...

#5 编辑:

从我的模型 "RoundDefinition" 中删除了 lombok 注释“@Data”,我自己写了 getter 和 setter 并且测试再次正常工作...... 使用龙目岛 v1.18.8

那么为什么lombok生成hashCode和equals函数时会失败....

太棒了,我终于到了可以继续的地步了...

当我测试了几次尝试时,我注意到我的测试以某种方式再次起作用。

当我 运行 带有配置文件的测试失败时,当 运行 没有配置文件时它们工作。 经过一些挖掘和重构后,我得到了项目的 pom 文件...

插件"maven-sufefire-plugin"被添加了2次这样

<project>
<profiles>
[...]
<profile>
 <id>unit-test</id>
  <plugins>
   [...]
   <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
     <argLine>
      ${argLine} -Dfile.encodeing=utf-8 -Duser.timezone=UTC
     </argLine>
    </configuration>
   </plugin>
[...]
<project>
 <build>

     <argLine>
      -Dfile.encodeing=utf-8 -Duser.timezone=UTC
     </argLine>
    </configuration>
   </plugin>
[...]

但是 属性 ${argLine} 根本没有在 pom 文件中设置。 所以我引入了一个新的 属性 <argLine> 并将这些参数放在那里……瞧,它起作用了…… 不知道为什么 hashcode 方法会抛出异常,但也许这对其他人也有帮助:-)
