java - 当我从第一类运行脚本测试用例运行两次时，我总共有 3 个测试用例，其中 2 个测试用例在父类中，1 个在子类中

Question

我有一个包，两个类，总共 3 个测试用例，两个测试用例在父类中，一个在子类中，但是当我从第一个类运行脚本测试用例时，运行两次。在开始时以及在从二等舱进行测试时再次进行。我仅在父类中启动应用程序

Answer 1

根据 JAVA 继承概念，如果我们将任何类扩展到其子类，则首先执行父类，然后执行子类。仅仅因为这个概念，我们就能够在Java中实现方法重写(用子方法重写父方法)。对于您的案例，您通过扩展 AdminLogin 类将“AdminLogin”编写为父类，将“EditMenuItem”编写为子类。因此，每当您尝试执行子类(EditMenuItem)时，将首先执行父类(AdminLogin)，然后执行子类。

接下来是 pom.xml，您首先调用父类，然后调用子类。按照给定的顺序，先执行父类，然后执行子类。当 selenium 尝试执行子进程时，它也应该执行父进程(根据继承概念)。这就是您的情况下父类运行两次的原因。

要解决此问题，请不要将 AdminLogin 类扩展到您的子类并保持 pom.xml 不变。通过这种方式，将执行第一个 AdminLogin，然后执行您在 pom.xml 文件中作为层次结构中的第二个类提到的子类。
