TestNG: All subsequent Test classes are skipped when @BeforeClass method fails?
提问by drkthng
My setup:
我的设置：
- A TestBase classcontaining a @BeforeClass method
- Several Test classesextending from TestBase class and also containing a @BeforeClass method
- testNG 6.8.8
- 甲TestBase类含有@BeforeClass方法
- 几个从 TestBase类扩展的Test 类，还包含一个 @BeforeClass 方法
- 测试NG 6.8.8
Why this setup?:
为什么这样设置？：
- I need the @BeforeClass in the TestBase class to provide setup that all testclasses will need and I don't want to repeat in every Test class. For example thread-id-dependent login credentials.
- TestBase class also instantiates the Selenium WebDriver
- I need the @BeforeClass in the Test classes to initialize everything that all @Test methods will need to use but that only needs to (or must) be built/invoked once for all tests. This includes calls to said WebDriver instance (that's why a "normal" constructor doesn't work here)
- 我需要 TestBase 类中的 @BeforeClass 来提供所有测试类都需要的设置，我不想在每个测试类中重复。例如，与线程 ID 相关的登录凭据。
- TestBase 类还实例化 Selenium WebDriver
- 我需要 Test 类中的 @BeforeClass 来初始化所有 @Test 方法将需要使用的所有内容，但只需要（或必须）为所有测试构建/调用一次。这包括对所述 WebDriver 实例的调用（这就是“普通”构造函数在这里不起作用的原因）
Here's what happens:
这是发生的事情：
When I run the tests via a testNG xml file and there is an exception within the @BeforeClassmethod of one of the Test classes, then all subsequent Test classes are skipped by TestNG.
当我通过 testNG xml 文件运行测试并且其中一个 Test 类的 @BeforeClass方法中存在异常时，TestNG 将跳过所有后续的 Test 类。
Why does this happen? How to prevent it?
为什么会发生这种情况？如何预防？
When I change the annotation in the TestBase class to @BeforeSuitefor example, then all tests are run, even if there is an exception in on of the @BeforeClass methods.
例如，当我将 TestBase 类中的注释更改为@BeforeSuite 时，即使 @BeforeClass 方法中存在异常，也会运行所有测试。
Example:
例子：
When you run the xml file, complete RunAllTestClasses02 class is skipped.
运行 xml 文件时，将跳过完整的 RunAllTestClasses02 类。
testNG xml file:
testNG xml 文件：
<?xml version="1.0" encoding="UTF-8"?>
<suite name = "MiscSuite">
<test name = "MiscTest">
<classes >
<class name="drkthng.misc.RunAllTestClasses01" />
<class name="drkthng.misc.RunAllTestClasses02" />
</classes>
</test>
</suite>
TestBase class with a @BeforeClass method:
带有 @BeforeClass 方法的 TestBase 类：
public abstract class RunAllTestClassesBase {
@BeforeClass
public void beforeClass() {
// do something that all Test classes will need
}
}
Test class that throws Exception within @BeforeClass method:
在@BeforeClass 方法中抛出异常的测试类：
public class RunAllTestClasses01 extends RunAllTestClassesBase {
@BeforeClass
public void beforeClass() {
Assert.assertTrue(false);
}
@Test
public void Test01() {
Assert.assertTrue(true);
}
}

This was a bug in Testng. solved in 6.9.5. Please upgrade.
这是Testng中的一个错误。在 6.9.5 中解决。请升级。

Try to add @AfterClass(alwaysrun = true)or/and @AfterMethod(alwaysrun=true)as by default they are skipped if either BeforeClass or BeforeMethod are not completed.
尝试添加@AfterClass(alwaysrun = true)或/和@AfterMethod(alwaysrun=true)默认情况下，如果 BeforeClass 或 BeforeMethod 未完成，它们将被跳过。
The documentation on testNG Configuration Failures, Policy, and alwaysRun explains whether/when configuration failures cause listener methods (alwaysRunand other listeners) to be skipped, failure policies and best practices.
testNG Configuration Failures、Policy 和 alwaysRun 文档解释了配置失败是否/何时导致侦听器方法（alwaysRun和其他侦听器）被跳过、失败策略和最佳实践。
