【问题描述】：
我正在使用 Selenium 进行自动化 - 页面对象模型 & TestNG & Java。我在 2 个类文件中有 2 个测试用例，我想并行运行我的所有测试 我将驱动程序和测试对象传递给我的所有页面。 当我的 testng.xml 使用 parallel="classes" 打开两个浏览器窗口并且仅在一个窗口中运行时，测试正在运行。另一个窗口关闭。 Eclipse 向我展示了空指针异常。 回答： 后来我明白这是关于在 ExtentReport 初始化中使用静态的。我在记者课上更正了我的代码。
测试类 1：
public class CreateXCase extends SeleniumBase
{
@BeforeTest(alwaysRun=true )
public void setTestDetails()
{
author = System.getProperty("user.name");
testcaseName="Verify that X case is successfully created";
testcaseDec = "Create X Case";
category="Regression";
}
@Test(priority=2,groups = {"Regression"})
public void createCaseWithNewParticipants() throws Exception
{
new LoginPage(driver, test).login().quickNavigation_CASE()
.navigateToCreateCase().enterApplicantInformation()
.navigateToCaseSection().createCase();
}
}
测试类 2：
public class CreateYcase extends SeleniumBase
{
@BeforeTest(alwaysRun=true )
public void setTestDetails()
{
author = System.getProperty("user.name");
testcaseName="Verify that Y case is successfully created";
testcaseDec = "Create Y Case";
category="Regression";
}
@Test(priority=1,groups = {"Regression"})
public void createCaseWithNewParticipants() throws Exception
{
new LoginPage(driver,test).login().quickNavigation_CASE()
.navigateToCreateCase().enterApplicantInformation()
.navigateToCaseSection().createCase();
}
SeleniumBase.java:
public class SeleniumBase extends Reporter implements Browser, Element
{
public static WebDriverWait wait;
@BeforeMethod(alwaysRun=true )
public void configureAndLaunch() throws IOException
{
driver = startApp(ReadPropertyFile.get("Browser"), ReadPropertyFile.get("URL"));
}
@Override
@AfterMethod (alwaysRun=true )
public void closeBrowser()
{
driver.quit();
}
@Override
public RemoteWebDriver startApp(String browser, String url)
{
try
{
if (browser.equalsIgnoreCase("chrome"))
{
System.setProperty("webdriver.chrome.driver", "./drivers/chromedriver.exe");
driver = new ChromeDriver();
}
else if (browser.equalsIgnoreCase("firefox"))
{
System.setProperty("webdriver.gecko.driver", "./drivers/geckodriver.exe");
driver = new FirefoxDriver();
}
else if (browser.equalsIgnoreCase("ie"))
{
System.setProperty("webdriver.ie.driver", "./drivers/IEDriverServer.exe");
driver = new InternetExplorerDriver();
}
driver.get(url);
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
driver.manage().window().maximize();
return driver;
}
catch (Exception e)
{
int a = e.toString().indexOf("Exception:");
String str = e.toString().substring(0, a + 30);
System.out.println(str + "Exception captured");
System.err.println("The Browser Could not be Launched. Hence Failed");
}
finally
{
takeSnap();
}
return null;
}

【问题讨论】：
-
您已经尝试过哪些更改？
-
@LeyonGudinho 如果我们设为静态，它将不会并行运行。为了能够并行运行，我们必须保持它不是静态的。
-
@Arun 这与您的 ExtentReport 变量有关，而不是 webdriver，因此您可以尝试将 ExtentReports 范围设为静态。我明天会对此进行调查，但同时尝试将报告设为静态。
-
将 ExtentReports 设为静态应该可以解决您的问题
-
如果您仍然遇到问题，请使用常用的东西。使用当前本地线程和 ExtentReportsManager 进行范围测试 - github.com/swtestacademy/ExtentReportsExample 或 github.com/vikas-thange/ExtentReports-TestNg-Integration 或 github.com/djangofan/extent-reporting-example
