在使用 TestNG 失败的测试用例的情况下重新运行整个班级

Question

我有一个使用 Appium 和 TestNG 开发的脚本设置。TestNG xml 包含多个类的执行，每个类都有多个测试用例。

例子：

Class1:

-Class1_Test1

-Class1_Test2

-Class1_Test3

Class2:

-Class2_Test1

-Class2_Test2

-Class2_Test3

我尝试集成 IRetryAnalyzer 但这只是调用失败的测试用例。要求是执行完整的 Class1，以防 Class1_Test2 在 Class1 失败之前立即失败，然后再进入 Class2？

询问的原因是应用程序是媒体播放器，如果由于网络/服务器问题导致媒体播放失败，则不需要执行下一个前进和后退测试用例，需要重新启动应用程序并重试进行进一步测试之前的所有步骤。

根据TestNg文档没有办法实现这一点，可能下面的答案可以帮助你

我正在使用小组测试。即使课堂上的某些测试失败，它也会继续测试。在您的类文件中，您可以定义如下组。public class myClass(){&nbsp; &nbsp; @Test(groups = {"abc"}, priority = 1)&nbsp; &nbsp; public void test1(){&nbsp; &nbsp; }&nbsp; &nbsp; @Test(groups = {"abc"}, priority = 2)&nbsp; &nbsp; public void test2(){&nbsp; &nbsp; }&nbsp; &nbsp; @Test(groups = {"abc"}, priority = 3)&nbsp; &nbsp; public void test3(){&nbsp; &nbsp; }}同样，您可以定义具有相同组名或不同组名的第二类。优先级决定了测试用例运行的顺序。您的 Testng.xml 文件将如下所示：<test name="any name">&nbsp; <groups>&nbsp; &nbsp; <run>&nbsp; &nbsp; &nbsp; <include name="abc"&nbsp; />&nbsp; &nbsp; &nbsp; <include name="any other group name"&nbsp; />&nbsp; &nbsp; </run>&nbsp; </groups>&nbsp; <classes>&nbsp; &nbsp; <class name="packageName.myClass"/>&nbsp; &nbsp; <class name="your_packageName.class2"/>&nbsp; </classes></test>packageName 是您的测试类所在的路径。如果您的测试类和 testng.xml 文件在同一个包中，则不需要 packageName。有关 Testng 中的测试方法的更多信息，请参阅此链接。

终于找到了重新运行整个班级的解决方法。我将其称为一种解决方法，因为从技术上讲，TestNG 不提供在任何时间点发生故障时重新执行 @BeforeTest 的方法。我发现最好的方法是没有@BeforeTest 部分，只有一个@Test 部分，并将所有测试用例作为函数，在定义的单个@Test 中调用。因此，如果在任何时间点发生故障，将调用@Test，其中包含按所需顺序包含的所有功能，包括设置功能。一旦观察到失败，重试逻辑就会重新运行整个 @Test 部分。示例：改动前：package <yourpackagename>;<import required packages>public class Home {&nbsp; &nbsp; private AppiumDriver<?> driver;&nbsp; &nbsp; private static final String url = "http://0.0.0.0:4723/wd/hub";&nbsp; &nbsp; <define your variables>&nbsp; &nbsp; @Parameters({"deviceOS", "DSN"})&nbsp;
