从@Test向Listeners传递TestNG DataProvider parallel=true的参数

Question

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;
}

常量。浏览器看起来像这个

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

基本上只生成2个数据"；铬"；以及"；边缘"；然后把它输入到我的@Test，它看起来像这个

@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侦听器

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);
}
}

由于@DataProvider(name = "dp", parallel = true)，将有2个线程同时运行。Chrome浏览器和Edge浏览器。我可以看到他们两个同时开始，并做一些测试。一旦测试完成，两个浏览器都会退出((。

我从testng.xml中运行它，它看起来像这个

?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>

我的问题是听众只打印一个线程。有时它会打印

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

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

有时它会打印

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

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

我的期望是这两个参数都可以打印(记录(，就像这样(不要担心时间戳(

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

Answer 1

在ITestResult 的ITestContext中设置属性

@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"));
}

以下方法将只执行一次

/**
* 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);

}

你会得到输出-类似于这个

DEBUG TestBase -ITestResult --> BROWSER is Chrome
DEBUG TestBase -ITestResult --> BROWSER is Edge
DEBUG TestBase -ITestContext --> Used Browser  : Edge --- Note this--

完成时只执行一次
