将TestNG DataProvider parallel = true的参数从@Test传递到侦听器

如何解决将TestNG DataProvider parallel = true的参数从@Test传递到侦听器

我让DataProvider生成一些数据并将其提供给我的@Test

@DataProvider(name = "dp",parallel = true)
public Object[][] getbrowser(Method m) {

  Iterator < String > iterator = Constants.browsers.iterator();
  String browser = null;
  Object[][] data = new Object[2][1];

  for (int i = 0; i < 2; i++) {
    if (iterator.hasNext()) {
      browser = iterator.next();
      data[i][0] = browser;
    }
  }

  return data;

}

Constants.browsers看起来像这样

public static final List<String> browsers = new ArrayList<>(
        Arrays.asList("Chrome","Edge"));

基本上只生成2个数据“ Chrome”和“ Edge”，然后将其提供给我的@Test，就像这样

@Test(dataProviderClass = TestUtilities.class,dataProvider = "dp")
public void testing(String browser,ITestContext context) throws InterruptedException {

  ITestResult result = Reporter.getCurrentTestResult();
  result.getmethod().setDescription(browser);

  context.setAttribute("browser",browser);

  initiate(browser,Constants.baseURL); //Instantiate Chrome or Edge WebDriver and go to the URL

  //  Do the testing

  closebrowser();
}

我已经设置了TestNG监听器

public class myListeners extends TestBase implements ITestListener,ISuiteListener {

  @Override
  public void onTestSuccess(ITestResult result) {

    String methodName = result.getmethod().getmethodName();

    String browser = result.getmethod().getDescription();
    log.debug("ITestResult --> broWSER is " + browser);

  }



  @Override
  public void onFinish(ITestContext context) {

    String usedbrowser = null;
    usedbrowser = (String) context.getAttribute("browser");
    log.debug("ITestContext --> Used browser  : " + usedbrowser);

  }
}

自@DataProvider(name = "dp",parallel = true)起，将同时有2个线程在运行。 Chrome浏览器和Edge浏览器。我可以看到它们同时开始并进行了一些测试。测试完成后，两个浏览器都将退出（）。

我从如下所示的testng.xml运行它

?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYstem "https://testng.org/testng-1.0.dtd" >

<suite name="My Test Suite" parallel="tests">

  <listeners>
    <listener class-name="myListeners.myListeners"></listener>
  </listeners>

  <test name="myTest" preserve-order="true">
    <classes>
      <class name="testCases.testing" />
    </classes>
  </test>
</suite>

我的问题是，侦听器仅打印线程之一。 有时会打印

18:38:02.110 DEBUG TestBase -ITestResult --> broWSER is Chrome

18:38:04.190 DEBUG TestBase -ITestContext --> Used browser : Chrome

有时会打印

18:38:02.110 DEBUG TestBase -ITestResult --> broWSER is Edge

18:38:04.190 DEBUG TestBase -ITestContext --> Used browser : Edge

我期望两个参数都可以像这样打印（记录）（不必担心时间戳）

18:38:02.110 DEBUG TestBase -ITestResult --> broWSER is Chrome

18:38:02.110 DEBUG TestBase -ITestResult --> broWSER is Edge

18:38:04.190 DEBUG TestBase -ITestContext --> Used browser : Chrome

18:38:04.190 DEBUG TestBase -ITestContext --> Used browser : Edge

我该怎么做？谢谢。

解决方法

按照在ITestContext中为ITestResult设置的方式设置属性

@Test(dataProviderClass = TestUtilities.class,dataProvider = "dp")
public void testing(String browser,ITestContext context) throws InterruptedException {

  ITestResult result = Reporter.getCurrentTestResult();
  // Changes here 
  result.setAttribute("browser",browser);

  context.setAttribute("browser",browser);

  initiate(browser,Constants.baseURL); //Instantiate Chrome or Edge WebDriver and go to the URL

  //  Do the testing

  closeBrowser();
}

---

@Override
  public void onTestSuccess(ITestResult result) {

    String methodName = result.getMethod().getMethodName();

    //String browser = result.getMethod().getDescription();
  // changes here
    log.debug("ITestResult --> BROWSER is " + (String) result.getAttribute("browser"));

  }

下面的方法将只执行一次

  /**
   * Invoked after all the test methods belonging to the classes inside the <test> 
   tag have run
   * and all their Configuration methods have been called.
   *
   * @param context The test context
   */

    @Override
      public void onFinish(ITestContext context) {
    
        String usedBrowser = null;
        usedBrowser = (String) context.getAttribute("browser");
        log.debug("ITestContext --> Used Browser  : " + usedBrowser);
    
      }

您将获得输出-类似于

DEBUG TestBase -ITestResult --> BROWSER is Chrome

DEBUG TestBase -ITestResult --> BROWSER is Edge

DEBUG TestBase -ITestContext --> Used Browser  : Edge --- Note this--

完成时仅执行一次
