我总共有3个测试用例，2个测试用例在父类中，1个在子类中，当我运行第一个类的脚本测试用例时，运行两次

Question

我有一个包两个类和总共3个测试用例两个测试用例在父类中，一个在子类中，但当我运行第一个类的脚本测试用例时，会运行两次。在开始时，以及在从第二类运行测试之后再次。我正在启动仅在父类中的应用程序

Answer 1

根据JAVA继承的概念，如果我们将任何类扩展到它的子类，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(。在您的案例中，通过扩展AdminLogin类，您已经将"AdminLogin"写成父类，将"EditMenuItem"写成子类。因此，每当您尝试执行子类(EditMenuItem(时，首先执行父类(AdminLogin(，然后执行子类。

接下来是pom.xml，首先调用父类，然后调用子类。按照给定的顺序，父类将首先执行，然后执行子类。当selenium试图执行child时，它也应该执行parent(根据继承概念(。这就是父类在您的情况下运行两次的原因。

要解决此问题，请不要将AdminLogin类扩展到您的子类，并保持pom.xml的原样。这样，将执行First 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。

Answer 2

老实说，我没有深入研究您的测试，也看不出您需要继承的真正原因。但是您可以尝试将父类标记为"摘要"。这样，测试将只在子类中执行。

我在c#和Nunit中使用过这种技术，但我想它在Java中的工作方式类似。
