测试期望异常，抛出异常（在输出中显示），但是测试仍然失败

在您的方法中，您正在捕获异常并记录消息（这是一种不好的做法，应记录堆栈跟踪），并且在测试中您声明测试的执行 必须
抛出a，

be.vdab.util.mens.MensException

只是重新抛出它，或者根本不将其捕获在要测试的方法/构造函数中。

选项1：

public Voertuig() {    this.nummerplaat = div.getNummerplaat();    this.Zitplaatsen = Zitplaatsen;    try {        //...        //pre in the try...        //...    } catch (MensException e) {        //System.out.println(e.getMessage());        //use a logger, not System.out        //in case you still want to use System.out        //then at least use the pre shown below        //e.printStackTrace(System.out);        //line above commented since there's no need to log        //and rethrow the exception        //the exception will be handled by the highest level execution        //and there it should be logged or use another strategy        throw e;    } }

选项2：

public Voertuig() {    this.nummerplaat = div.getNummerplaat();    this.Zitplaatsen = Zitplaatsen;//remove the try//    try {    //...    //pre in the try...    //...//remove the catch//    } catch (MensException e) {//        System.out.println(e.getMessage());//    } }

IMO我将使用选项2而不是选项1。
