无法在Selenium中截屏

我正在尝试捕获每个故障发生的屏幕截图并编写下面的代码,但这不起作用。

public class TestFile {

    WebDriver driver = new FirefoxDriver();

    @Test   
    public void Testone(){
        driver.get("http://www.google.com/");           
    }

    @AfterMethod(alwaysRun=true)
    public void catchExceptions(ITestResult result){
        System.out.println("result"+result);
        String methodName = result.getName();
        System.out.println(methodName);

        if(!result.isSuccess()){         
            try { 
                File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
                FileUtils.copyFile(scrFile,new File("C:screenshot2.png" ));
            } catch (IOException e1) {
                e1.printStackTrace();
            }       
        }
    }
}

这是失败的

文件scrFile =((TakesScreenshot)驱动程序).getScreenshotAs(OutputType.FILE);


堆栈跟踪:

进口清单:

package com.example.tests;
import org.testng.annotations.Test;
import java.io.File;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import org.apache.commons.io.FileUtils;
import org.junit.Before;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.Augmenter;

import org.testng.ITestResult;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;  

您共享的堆栈跟踪不是堆栈跟踪,但我认为是testng日志。
你提供的例子实际上是有效的。 我只是让测试失败,因为在@AfterMethod中,只有当测试失败时才会执行截图:if(!result.isSuccess())
然后当我再次运行这个例子时,我得到了:
java.io.FileNotFoundException:C: screenshot2.png(访问被拒绝)
然后我改变了图片的位置在D上:权限是正确的,它的工作是端到端的,我可以看到截图。

干杯

        assert false;

    }

    @AfterMethod(alwaysRun = true)
    public void catchExceptions(ITestResult result) {
        System.out.println("result" + result);
        String methodName = result.getName();
        System.out.println(methodName);

        if (!result.isSuccess()) {

            try {

                File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
                FileUtils.copyFile(scrFile, new File("C:screenshot2.png"));
            } catch (IOException e1) {
                e1.printStackTrace();
            }

        }
    }
}

嗨sinisa229 mihajlovski,

你的脚本工作正常。 但脚本中有轻微的变化。 如果我不会评论该行“assert false”,它会给出错误。


尝试这个 :

 WebDriver augmentedDriver = new Augmenter().augment(driver);
    File screenshot = ((TakesScreenshot)augmentedDriver).
                        getScreenshotAs(OutputType.FILE);

代替

File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
