自动化截图

Automation screenshot

我目前正在从事一个自动化项目,我创建了这个简单的程序来报告测试信息并截取屏幕截图。

package ReportTest;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.ITestResult;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.Test;
import com.relevantcodes.extentreports.ExtentReports;
import com.relevantcodes.extentreports.ExtentTest;
import com.relevantcodes.extentreports.LogStatus;

import ReportTest.Utitlity;
public class ReportTest {


ExtentReports report;
ExtentTest logger;
WebDriver driver;


@Test
public void verifyBlogTitle()
{

    report =new ExtentReports("C:\Users\reganc3\desktop\report\LearnAutomation.html");


    logger=report.startTest("VerifyBlogTitle");

    driver = new FirefoxDriver();

    driver.manage().window().maximize();

    logger.log(LogStatus.INFO, "Browser started");

    driver.get("http://www.learn-automation.com");

    logger.log(LogStatus.INFO, "Application is up and running");

    String title = driver.getTitle();

    Assert.assertTrue(title.contains("Selenium"));

    logger.log(LogStatus.PASS, "Title Verified");
}

@AfterMethod
public void tearDown(ITestResult result)
{
    if(result.getStatus()==ITestResult.FAILURE)
    {

    String screenshot_path = Utitlity.captureScreenshot(driver, result.getName());
    logger.log(LogStatus.FAIL, "TitleVerification", screenshot_path);

    }

    report.endTest(logger);
    report.flush();

    driver.get("C:\Users\reganc3\desktop\report\LearnAutomation.html");
}
}

这是我的实用程序 class,它被调用以截取屏幕截图

package ReportTest;



import java.io.File;

import org.apache.commons.io.FileUtils;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebDriverException;
import java.util.*;

public class Utitlity {



public static String captureScreenshot(WebDriver driver, String screenshotName)
{
    try
    {
        TakesScreenshot ts=(TakesScreenshot)driver;

        File source=ts.getScreenshotAs(OutputType.FILE);

        String dest = " C:\Users\reganc3\desktop\ " +screenshotName+ ".png";

        File destination=new File(dest);

        FileUtils.copyFile(source, destination);

        System.out.println("Screenshot taken");

        return dest;

    }
    catch (Exception e)
    {
        System.out.println("Exception while taking screenshot "+e.getMessage());
        return e.getMessage();
    }

}
 }

我收到以下错误

**截屏时出现异常 null

我对 Selenium 和 TestNG 很陌生,所以我基本上是在找人来阐明这一点,并给我一些正确方向的指导,并了解我的代码实际发生了什么错误。

提前致谢。

我目前正在使用这种方法在我的测试中截取屏幕截图:

import java.io.File;
import java.io.IOException;
import org.apache.commons.io.FileUtils;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;

 public void takeScreenShot(WebDriver driver, String methodName) {
        File screenshotFile=((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
            try {
                FileUtils.copyFile(screenshotFile,new
 File("Screenshots\"+methodName+" "+GetTimeStampValue()+".png"));
                } catch (IOException e) {
                    e.printStackTrace();
                }
        }

以及获取时间戳的方法:

import java.io.IOException;
import java.util.Calendar;
import java.util.Date;

public  String GetTimeStampValue()throws IOException{
    Calendar cal = Calendar.getInstance();       
    Date time=cal.getTime();
    String timestamp=time.toString();
    String systime=timestamp.replace(":", "-");
    return systime;
}

我为我的代码使用了错误版本的 ExtentReport。

我使用的代码是针对较新版本的 ExtentReport,而我拥有的 Maven 依赖项指向旧版本。当我将依赖项更新到最新版本时,代码本身运行良好。

Robot r=new Robot();
r.keyPress(KeyEvent.VK_PRINTSCREEN);
r.keyRelease(KeyEvent.VK_PRINTSCREEN);
