我正在尝试使用TestNG中的ExtentReports准备测试执行报告。以下是我的代码 -
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
import com.relevantcodes.extentreports.ExtentReports;
import com.relevantcodes.extentreports.LogStatus;
public class TestNGExample {
WebDriver driver;
WebElement wb;
ExtentReports report = ExtentReports.get(TestNGExample.class);
@BeforeTest
public void open(){
driver = new FirefoxDriver();
driver.get("https://www.google.co.in/?gws_rd=ssl");
driver.manage().window().maximize();
report.init("E:\\Report\\report.html", true);
report.log(LogStatus.INFO, "Browser is up and running");
}//open
@AfterClass
public void tearDown(){
report.log(LogStatus.INFO, "Test Completed");
driver.close();
driver.quit();
}//tearDown
@Test
public void First(){
report.log(LogStatus.INFO, "Starting the test process");
String s = driver.findElement(By.xpath(".//*[@id='hplogo']")).getAttribute("Title");
Assert.assertEquals("Google", s);
report.log(LogStatus.PASS, "Checking for the result");
report.attachScreenshot("E:\\Report.png");
report.endTest();
}//first
}//TestNGExample
运行此代码后，我将从ExtentReports生成NullPointerException。 下面我将提出完整的例外情况 -

答案 0 :(得分：3)
通过设置文件路径初始化报告。
report.init("E:\\Report\\report.html", true);
您必须在向其添加日志之前开始测试
report.startTest("TestName");
bcoz在test下添加了所有日志事件。由于测试本身尚未启动，因此抛出空指针异常
<强>码：
@BeforeTest
public void open(){
driver = new FirefoxDriver();
driver.get("https://www.google.co.in/?gws_rd=ssl");
driver.manage().window().maximize();
report.init("E:\\Report\\report.html", true);
report.startTest("TestName");//start the test before adding logs to it
report.log(LogStatus.INFO, "Browser is up and running");
}//open
我已经测试了上面的代码，它运行正常。
