测试通过了,但是并不是我想要的。
因为我在执行该测试时,还没有写修改附加参量的方法。本测试是期待不通过的。
分析具体内部怎么运行的不知道,但是应该是前面的引用修改状态,后面的就跟着变了。
之前为了少写几行代码,非强检器具、参量、附加参量这三个用的是同一个测量范围对象,不知道具体的执行过程,但是猜想应该是这东西的问题。
尝试写了一下克隆方法,每次都克隆一个新对象。
网上写的克隆方法,总觉得不好,最后还要强转。
在实体中写的克隆对象的方法,就是new一个然后返回去呗。
public AccuracyEmbeddable cloneAccuracyEmbeddable() { AccuracyEmbeddable accuracyEmbeddable = new AccuracyEmbeddable(); accuracyEmbeddable.setMinAccuracyValue(this.minAccuracyValue); accuracyEmbeddable.setMinAccuracyUnit(this.minAccuracyUnit); accuracyEmbeddable.setMaxAccuracyValue(this.maxAccuracyValue); accuracyEmbeddable.setMaxAccuracyUnit(this.maxAccuracyUnit); accuracyEmbeddable.prePersist(); return accuracyEmbeddable; } public MeasureScaleEmbeddable cloneMeasureScaleEmbeddable() { MeasureScaleEmbeddable measureScaleEmbeddable = new MeasureScaleEmbeddable(); measureScaleEmbeddable.setMinMeasureScaleValue(this.minMeasureScaleValue); measureScaleEmbeddable.setMinMeasureScaleUnit(this.minMeasureScaleUnit); measureScaleEmbeddable.setMaxMeasureScaleValue(this.maxMeasureScaleValue); measureScaleEmbeddable.setMaxMeasureScaleUnit(this.maxMeasureScaleUnit); measureScaleEmbeddable.prePersist(); return measureScaleEmbeddable; }
然后就用clone方法获取新对象并设置。
additionalParameter1.setMeasureScale(measureScaleEmbeddable1.cloneMeasureScaleEmbeddable()); additionalParameter2.setMeasureScale(measureScaleEmbeddable2.cloneMeasureScaleEmbeddable()); additionalParameter3.setMeasureScale(measureScaleEmbeddable3.cloneMeasureScaleEmbeddable());
再次执行测试,出现了预期中的错误,证明就是对象引用的问题。
总结测试驱动开发,如果我是写完方法再写测试,这应该是一个能通过却有问题的测试,而我却不知道。

摘要:判断参数是否为待判断的参数克隆一个对象要克隆的目标对象克隆节点,绑定事件的有问题,暂不处理克隆在当前作用域,在全局克隆其它对象,通过识别复制后的对象与原对象是否相同来决定传不传参数,像数组是不能传参数的使用防止对象重写了方法支持节点克隆 (function(){ var toString=Object.prototype.toString,gObj={},cloneHelper=f...
摘要:原始类型对象指的是字符串数值布尔值,引用类型对象指的是数组对象函数。既然对象分为这两类,他们的复制克隆也是有差别的。总结根据上面的情况,另外,克隆引用对象必须采用完整克隆深度克隆,包括对象的值也是一个对象也要进行完整克隆深度克隆。 前言 之前有人问我如何克隆一个JS对象,我当时没答上来;过后我查资料弄懂了这个问题,现在整理成文。 正文 JavaScript的一切实例都是对象,但他们也分...
摘要:在聊以下简称深度克隆之前,我们先来了解一下中对象的组成。克隆或者拷贝分为种浅度克隆深度克隆。浅度克隆基本类型为值传递,对象仍为引用传递。 该文转载自http://www.cnblogs.com/zichi/p/4568150.html,有部分修改。 在聊JavaScript(以下简称js)深度克隆之前,我们先来了解一下js中对象的组成。在 js 中一切实例皆是对象,具体分为 原始类型 ...
摘要:多个窗口意味着多个全局环境,不同的全局环境拥有不同的全局对象,从而拥有不同的内置类型构造函数。比如,表达式会返回,因为属性得到的仅仅是构造函数,而且是可以被手动更改的,只是返回的构造函数的名字,它并不返回类名。 原文:ES6时代,你真的会克隆对象吗(二) 上一篇,我们从Symbol和是否可枚举以及属性描述符的角度分析了ES6下怎么浅拷贝一个对象,发表在掘金和segmentfault上(...
