如何使用 TestNG & Java 在方法执行期间设置调用计数

Question

我有一个测试方法，我手动执行了200次。

@Test(priority=2, invocationCount = 200)
public void inviteTalents() throws InterruptedException
{
  logger.log(Status.INFO, "Count " + logins[count]);
}

如何设置调用计数变量？我试过这样的东西，但没有用。有帮助吗？

  @BeforeMethod
  public void setUp(Method method, ITestContext context) {

    if(method.getName().equals("test3"))
    {
        ITestNGMethod currentTestNGMethod = null;
        for (ITestNGMethod testNGMethod : context.getAllTestMethods())
        {
          if (testNGMethod.getInstance() == this)
          {
            currentTestNGMethod = testNGMethod;
            break;
          }
        }
        currentTestNGMethod.setInvocationCount(count);  
    }
  }

您可以使用 IAnnotationTransformer 实现来完成此操作。

下面的示例展示了如何通过 JVM 参数传入方法名称和调用计数，以及注释转换器实现如何在运行时更改调用计数。

package com.rationaleemotions.Whosebug.qn51160440;

import org.testng.ITestResult;
import org.testng.Reporter;
import org.testng.annotations.Test;

public class TestClassSample {
  @Test
  public void fooTest() {
    ITestResult r = Reporter.getCurrentTestResult();
    String methodname = r.getMethod().getMethodName();
    System.err.println(
        "Running " + methodname + "() on Thread [" + Thread.currentThread().getId() + "]");
  }
}

这是注释转换器的样子

package com.rationaleemotions.Whosebug.qn51160440;

import java.lang.reflect.Constructor;
import java.lang.reflect.Method;
import org.testng.IAnnotationTransformer;
import org.testng.annotations.ITestAnnotation;

public class AnnotationTransformerImpl implements IAnnotationTransformer {

  @Override
  public void transform(
      ITestAnnotation annotation, Class testClass, Constructor testConstructor, Method testMethod) {
    //Pass the value via JVM argument -Dkvp=someMethod=400
    //Here "someMethod" is the name of the method and 400 is the invocation count value
    String kvp = System.getProperty("kvp", "fooTest=200");
    String keyValue[] = kvp.split("=");
    if (keyValue.length != 2) {
      return;
    }
    if (!testMethod.getName().equalsIgnoreCase(keyValue[0])) {
      return;
    }
    annotation.setInvocationCount(Integer.parseInt(keyValue[1]));
    annotation.setThreadPoolSize(25);
  }
}

套件文件如下所示

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="45160355_Suite" parallel="methods" verbose="2" >

        <listener
          class-name="com.rationaleemotions.Whosebug.qn51160440.AnnotationTransformerImpl"/>
    </listeners>
    <test name="45160355_test" verbose="2">
        <classes>
            <class name="com.rationaleemotions.Whosebug.qn51160440.TestClassSample"/>
