java TestNG跨浏览器测试在启动第一个浏览器后失败
我试图在不同的浏览器上运行一些基本测试，但在启动第一个浏览器（在本例中为Firefox）后，测试失败一次，并且无法执行Chrome和IE浏览器
使用TestNG注释的Java代码-
package com.Selenium_Practice;
import java.util.concurrent.TimeUnit;
import junit.framework.Assert;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.openqa.selenium.opera.OperaDriver;
import org.openqa.selenium.safari.SafariDriver;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
import com.relevantcodes.extentreports.ExtentReports;
import com.relevantcodes.extentreports.LogStatus;
public class CrossBrowserTestingUsingTestNG {
WebDriver driver;
ExtentReports report = ExtentReports.get(CrossBrowserTestingUsingTestNG.class);
@SuppressWarnings("deprecation")
@Test
@Parameters("browser")
public void CrossBrowserCodeBrowser(String browserName){
report.init("E:\\Report\\CrossBrowserTestingUsingTestNG.html", true);
report.startTest("Starting the test for CrossBrowserTestingUsingTestNG class");
if(browserName.equalsIgnoreCase("firefox")){
driver = new FirefoxDriver();
report.log(LogStatus.INFO, "Firefox browser is up and running");
}//if
else if(browserName.equalsIgnoreCase("chrome")){
System.setProperty("webDriver.chrome.driver", "E:\\Driver\\chromedriver.exe");
driver = new ChromeDriver();
report.log(LogStatus.INFO, "Chrome browser is up and runnning");
}//else if
else if(browserName.equalsIgnoreCase("ie")){
System.setProperty("webDriver.chrome.driver", "E:\\Driver\\IEDriverServer.exe");
driver = new InternetExplorerDriver();
report.log(LogStatus.INFO, "IE is up and running");
}//else if
driver.manage().window().maximize();
driver.get("http://stackoverflow.com/questions/31747315/getting-nullpointerexception-when-trying-to-generate-test-reports-using-extentre/31752389#31752389");
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.findElement(By.xpath(".//*[@id='question-header']/h1/a")).getAttribute("href");
driver.findElement(By.xpath(".//*[@id='question-header']/h1/a")).getTagName();
System.out.println("Link : "+driver.findElement(By.xpath(".//*[@id='question-header']/h1/a")).getAttribute("href"));
System.out.println("Question : "+driver.findElement(By.xpath(".//*[@id='question-header']/h1/a")).getTagName());
Assert.assertEquals("a", driver.findElement(By.xpath(".//*[@id='question-header']/h1/a")).getTagName());
report.log(LogStatus.PASS, "Both are equal");
report.endTest();
driver.quit();
}//CrossBrowserCodeBrowser
}//CrossBrowserTestingUsingTestNG
试衣-

使用TestNG运行XML文件后，我得到以下结果-

更新的XML文件- 在下面的XML文件中，我将参数放在类之外
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="CrossBrowserTesting" parallel="none">

输出- 运行更改后的XM文件后，我得到了相同的结果

参数标记应该在类之外
