是否有可能在测试类中的测试级套件级别创建一个超时，而不是单个方法

我正在研究我们在testng中遇到的问题。我想知道是否有一种方法可以在测试类级别上指定超时，而不是单个方法。我知道在套件XML级别上的"超时"，但这然后适用于每个测试类中的每种测试方法。

我真的可以指定适用于XML中每个类的超时，因此我们可以考虑改进这些类。

这是不支持的。但是Testng确实为您提供了使用功能，您应该能够在很少的努力中自行构建它。[我正在使用testng 7.0.0-beta7为此，这是发布此答案时最新发布的testng版本]

您首先需要创建一个自定义注释，该注释可用于在班级级别定义超时。
然后，您构建了org.testng.IAnnotationTransformer的实现，该实现可以从测试方法的声明类中读取此自定义注释的值，如果存在注释，则它将更改@Test注释的timeout属性。

这是一个完整的fled示例，显示了这一点。

自定义注释如下所示：

import static java.lang.annotation.ElementType.TYPE;
import java.lang.annotation.Retention;
import java.lang.annotation.Target;
@Retention(java.lang.annotation.RetentionPolicy.RUNTIME)
@Target({TYPE})
public @interface Timeout {
  long inMs() default 0;
}

消耗上述自定义注释的测试类看起来像

import java.util.concurrent.TimeUnit;
import org.testng.annotations.Test;
@Timeout(inMs = 15)
public class TestClass1 {
  @Test
  public void sleepFor10Ms() throws InterruptedException {
    TimeUnit.MILLISECONDS.sleep(10);
  }
  @Test
  public void sleepFor20Ms() throws InterruptedException {
    TimeUnit.MILLISECONDS.sleep(20);
  }
}

import java.util.concurrent.TimeUnit;
import org.testng.annotations.Test;
@Timeout(inMs = 5)
public class TestClass2 {
  @Test
  public void sleepFor10Ms() throws InterruptedException {
    TimeUnit.MILLISECONDS.sleep(10);
  }
  @Test
  public void sleepFor20Ms() throws InterruptedException {
    TimeUnit.MILLISECONDS.sleep(20);
  }
}

注释变压器看起来像

import java.lang.reflect.Constructor;
import java.lang.reflect.Method;
import org.testng.IAnnotationTransformer;
import org.testng.annotations.ITestAnnotation;
public class TimeoutSetter implements IAnnotationTransformer {
  @Override
  public void transform(
      ITestAnnotation annotation, Class testClass, Constructor testConstructor, Method testMethod) {
    if (testMethod == null) {
      return;
    }
    Timeout timeout = testMethod.getDeclaringClass().getAnnotation(Timeout.class);
    if (timeout == null) {
      return;
    }
    annotation.setTimeOut(timeout.inMs());
  }
}

这是套件文件的样子

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite" verbose="2">
  <listeners>
    <listener class-name="com.rationaleemotions.stackoverflow.qn57307245.TimeoutSetter"/>
  </listeners>
  <test name="Test">
    <classes>
      <class name="com.rationaleemotions.stackoverflow.qn57307245.TestClass1"/>
      <class name="com.rationaleemotions.stackoverflow.qn57307245.TestClass2"/>
    </classes>
  </test>
</suite>

超时只能以两种方式配置。

在套房级别。
在每种测试方法中。

基本上测试类中的测试类包含您的测试方法，这是您对测试条件的主张(在您的情况下，基于超时(，因此它们只是正常的Java类。

您可以尝试将单个测试方法保留为每个测试ng类，并将超时添加到该方法中，也可以创建一个外部方法，该方法将根据方法执行时间进行通过或失败决定。
