Question

所以给了我一些代码，我不得不为其编写方法，打印列表的大小，第一个元素和其他一些东西，我做了所有这些。虽然对于该项目的下一部分，我必须为其编写Junit测试，但是我只有getter，setter和tostring方法，所以我不知道我应该测试什么。我知道如何进行junit测试，我为此设置了一个类，但我只是不知道我应该测试什么。我只为具有实际计算方法的测试编写过代码，因此不确定是否应该为getter和setter编写junit测试。这是我的班级和我的主班。我真的不能向该类添加更多方法，因为我已经完成了我为程序规格所需做的所有事情。这是我的班级和我的主要班级。

public class FishData {
    private String species;  //species of fish
    private int minSize;  //min size allowed in inches
    private String season;  //fishing season
    private int limit;  //number
    private Boolean willEat;
    //constructor
    FishData(String s1, int m, String s2, int I, Boolean w){
        species = s1;
        minSize = m;
        season = s2;
        limit = I;
        willEat = w;
    }
    public String toString(){
        return species + "" + minSize + "" + season + "" + limit + "" + willEat;
    }
    public String getName(){
        return this.species;
    }
    public String getSpecies(){
        return this.species;
    }
    public String getSeason(){
        return this.season;
    }
    public Boolean getWillEat(){
        return this.willEat;
    }
    public void setSpecies(String species) {
        this.species = species;
    }
    public void setSeason(String season) {
        this.season = season;
    }
    public void setWillEat(Boolean willEat) {
        this.willEat = willEat;
    }
    public void setminSize(int minSize) {
        this.minSize = minSize;
    }
    public void setlimit(int limit) {
        this.limit = limit;
    }

}

测试getter设置器没有意义，但是有时，我们可能已经定制了getter和setter，在这种情况下，单元测试非常方便，可以避免错误。

我已使用OpenPojo测试我的Java DTO。

注意：您需要提供DTO软件包名称以及名称过滤器（可选）。我正在测试给定程序包下所有以Dto结尾的类。

final Validator validator = ValidatorBuilder.create()
                .with(new GetterMustExistRule())
                .with(new SetterMustExistRule())
                .with(new GetterTester())
                .with(new SetterTester())
                .with(new ReflectionToStringTester())
                .build()

final List<PojoClass> pojos = PojoClassFactory.getPojoClassesRecursively("com.myProject.component.model", new FilterClassName("\\w*Dto*\$"))
Assert.assertTrue(validator.validate(pojos));
