java - 并行执行在 Selenium 页面对象模型中不起作用

Question

我正在使用 Selenium - 页面对象模型、TestNG 和 Java 进行自动化。我在 2 个类文件中有 2 个测试用例，我想并行运行所有测试 我将驱动程序和测试对象传递到我的所有页面。 当使用并行=“类”运行我的 testng.xml 时，打开了两个浏览器窗口，并且仅在一个窗口中运行测试。另一个窗口是关闭的。 Eclipse 向我展示了空指针异常。 回答: 后来我明白这是关于 ExtentReport 初始化中静态的使用。我在记者课上更正了我的代码。

测试 1 类:

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 2 类:

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
     {

Answer 1

将 ExtentReport 变量“extent”设为静态解决了我的问题。 例如:public static ExtentReports 范围； 我也修改了问题中的代码。

由于我在一个类中只有一个@Test，所以parallel="methods"在我的情况下没有用。
