Question

我有两个班级baseClass和TesCaseLoginPage。当我在尝试在没有任何Report / Logger的情况下执行TesCaseLoginPage类（ExtentReport），测试用例正在通过。但是，当我得到延伸报告在我的代码中，我得到NullPointerException。请你帮助我

我在第51行写了report.endTest(logger);。试图发表评论这一行然后执行。这次我在第50行中得到了相同的错误，即

logger.log(LogStatus.INFO,"Browser Closed");。所以每次我评论错误行时，只在新的日志相关行中获得相同的错误。

错误日志如下：

以下是代码：

baseClass.java

public class baseClass

    public void setUP()
    {
        driver=BrowserFactory.getBrowser("chrome");
        driver.get(DataproviderFactory.getConfig().getApplicationurl());
    }

    public void loginIntoApplication()
    {       
        LoginPage login=PageFactory.initElements(driver, LoginPage.class);
        login.Login(DataproviderFactory.getExcel().getData(0, 0, 0), 
        DataproviderFactory.getExcel().getData(0, 0, 1));
    }

    public String LoginVerification()
    {
        try {
            Thread.sleep(5000);
        } catch (Exception e) {
        System.out.println(e.getMessage());
        }
        //WebDriverWait wait=new WebDriverWait(driver, 20);
        //wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//li[@id='wp-admin-bar-my-account']/a")));

        loginText=driver.findElement(By.xpath("//li[@id='wp-admin-bar-my-account']/a")).getText();
        logger.log(LogStatus.INFO, "Logiin account text has been captured successfully");
        return loginText;
    }

    public void TearDown()
    {
        driver.quit();
    }
}

testCaseLoginPage.java

    //baseClass base=PageFactory.initElements(driver, baseClass.class);

    @BeforeTest
    public void initial()
    {
        base.setUP();
    }

    @Test(priority=1)
    public void login()
    {

        base.loginIntoApplication();
        try {
            Thread.sleep(5000);

            System.out.println(e.getMessage());
        }
        //WebDriverWait wait=new WebDriverWait(driver, 20);
        //wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//a[contains(.,'Howdy')]")));
        logger.log(LogStatus.INFO, "Logiin into applicaion successfully");
        //LoginPage login=PageFactory.initElements(driver, LoginPage.class);

        LoginPage login=new LoginPage(driver);
        base.LoginVerification();
        System.out.println("Login Text : "+base.loginText);

        Assert.assertEquals(base.loginText, login.Exp,"Unable to verify login verification");   
        logger.log(LogStatus.PASS, "Verified login account with expected user successfully");

    }

    @AfterTest
    public void close()
    {
        base.TearDown();
        logger.log(LogStatus.INFO, "Browser Closed");
        report.endTest(logger);
        report.flush();
    }
}
