Java driver.getScreenshotAs（OutputType.FILE）无法将所有屏幕截图保存到目标中

java selenium

Java driver.getScreenshotAs（OutputType.FILE）无法将所有屏幕截图保存到目标中,java,selenium,screenshot,extentreports,Java,Selenium,Screenshot,Extentreports,我使用以下方法在我的项目中截图：- public String getScreenShot(String imageName) { String snapShot = null; try { if (imageName.equals("")) { imageName = "blank"; } Calendar cal = Calendar.getInstance(); Date currentTimeStamp = cal.getTime();

我使用以下方法在我的项目中截图：-

public String getScreenShot(String imageName) {
String snapShot = null;
try {
    if (imageName.equals("")) {
        imageName = "blank";
    }
    Calendar cal = Calendar.getInstance();
    Date currentTimeStamp = cal.getTime();
    String timeInFormat = formater.format(currentTimeStamp);
    File src = driv.getScreenshotAs(OutputType.FILE);
    String screenShotLocation = System.getProperty("user.dir") + "/screenPrints/";
    File des = new File(screenShotLocation + imageName + "_" + timeInFormat + ".png");
    FileUtils.copyFile(src, des);
    snapShot = des.toString();
    i++;        //i counts the no of times control coming into getScreenShot method 
    System.out.println(i);


} catch (Exception e) {
    System.out.println("The ScreenShot could not be taken\n" + e);
        e.printStackTrace();
    }
    return snapShot;
}
我使用下面的代码行调用上述方法：-

screen = getScreenShot("");
它在getScreenShot（）方法中运行了158次，并在控制台中将i值显示为158。但它能够将134张屏幕打印保存在目标文件夹中。如果我们在调用此方法之前包含1秒的间隔，则可以保存确切的no 目标文件夹中的屏幕截图

Thread.sleep(1000);
screen = getScreenShot("");
看起来执行速度如此之快，以至于跳过了目标文件夹中的保存部分。Thread.sleep（）大大降低了性能。有人能提出更好的解决方案吗。提前感谢。

可能有几个文件同名。我认为，您的
timeInFormat
格式最多为秒&您在一秒内拍摄了多个屏幕截图。要解决此问题，您可以将
timeInFormat
的格式设置为毫秒或微秒。不过，还有其他黑客。换线就行了

String timeInFormat = formater.format(currentTimeStamp);
到

我希望有帮助。

有两件事你需要考虑如下：

screen = getScreenShot();

TakesScreenshot ts = (TakesScreenshot) driv;
File src = ts.getScreenshotAs(OutputType.FILE);

public int getScreenShot() {

    String snapShot = null; //possibly not needed, we are returning int i
    int i = 0;
    String imageName = "blank";
    try {
        Calendar cal = Calendar.getInstance();
        Date currentTimeStamp = cal.getTime();
        String timeInFormat = formater.format(currentTimeStamp);
        TakesScreenshot ts = (TakesScreenshot) driv;
        File src = ts.getScreenshotAs(OutputType.FILE);
        String screenShotLocation = System.getProperty("user.dir") + "/screenPrints/";
        File des = new File(screenShotLocation + imageName + "_" + timeInFormat + ".png");
        FileUtils.copyFile(src, des);
        snapShot = des.toString(); //not needed as we are not using, returning int i
        i++; //i counts the no of times control coming into getScreenShot method 
        System.out.println(i);
    } catch (Exception e) {
        System.out.println("The ScreenShot could not be taken\n" + e);
        e.printStackTrace();
    }
    return i;
}

int screen = getScreenShot();
  • 如果使用包含文本blank的名称保存屏幕截图，可以将方法的签名更改为：

    public String getScreenShot() //removing String imageName
    您可以从
    main（）
    /
    @Test
    调用此方法，如下所示：

    screen = getScreenShot();

    TakesScreenshot ts = (TakesScreenshot) driv;
File src = ts.getScreenshotAs(OutputType.FILE);

    public int getScreenShot() {

    String snapShot = null; //possibly not needed, we are returning int i
    int i = 0;
    String imageName = "blank";
    try {
        Calendar cal = Calendar.getInstance();
        Date currentTimeStamp = cal.getTime();
        String timeInFormat = formater.format(currentTimeStamp);
        TakesScreenshot ts = (TakesScreenshot) driv;
        File src = ts.getScreenshotAs(OutputType.FILE);
        String screenShotLocation = System.getProperty("user.dir") + "/screenPrints/";
        File des = new File(screenShotLocation + imageName + "_" + timeInFormat + ".png");
        FileUtils.copyFile(src, des);
        snapShot = des.toString(); //not needed as we are not using, returning int i
        i++; //i counts the no of times control coming into getScreenShot method 
        System.out.println(i);
    } catch (Exception e) {
        System.out.println("The ScreenShot could not be taken\n" + e);
        e.printStackTrace();
    }
    return i;
}

    int screen = getScreenShot();
  • 调用的
    getScreenshotAs（）
    时，必须按如下方式强制转换WebDriver实例driv：

    screen = getScreenShot();

    TakesScreenshot ts = (TakesScreenshot) driv;
File src = ts.getScreenshotAs(OutputType.FILE);

    public int getScreenShot() {

    String snapShot = null; //possibly not needed, we are returning int i
    int i = 0;
    String imageName = "blank";
    try {
        Calendar cal = Calendar.getInstance();
        Date currentTimeStamp = cal.getTime();
        String timeInFormat = formater.format(currentTimeStamp);
        TakesScreenshot ts = (TakesScreenshot) driv;
        File src = ts.getScreenshotAs(OutputType.FILE);
        String screenShotLocation = System.getProperty("user.dir") + "/screenPrints/";
        File des = new File(screenShotLocation + imageName + "_" + timeInFormat + ".png");
        FileUtils.copyFile(src, des);
        snapShot = des.toString(); //not needed as we are not using, returning int i
        i++; //i counts the no of times control coming into getScreenShot method 
        System.out.println(i);
    } catch (Exception e) {
        System.out.println("The ScreenShot could not be taken\n" + e);
        e.printStackTrace();
    }
    return i;
}

    int screen = getScreenShot();
  • 您需要决定要将
    字符串
    作为des.toString（）返回什么或
    int
    asi

  • 带有小tweek的
    getScreenShot（）
    方法的代码块如下所示：

    screen = getScreenShot();

    TakesScreenshot ts = (TakesScreenshot) driv;
File src = ts.getScreenshotAs(OutputType.FILE);

    public int getScreenShot() {

    String snapShot = null; //possibly not needed, we are returning int i
    int i = 0;
    String imageName = "blank";
    try {
        Calendar cal = Calendar.getInstance();
        Date currentTimeStamp = cal.getTime();
        String timeInFormat = formater.format(currentTimeStamp);
        TakesScreenshot ts = (TakesScreenshot) driv;
        File src = ts.getScreenshotAs(OutputType.FILE);
        String screenShotLocation = System.getProperty("user.dir") + "/screenPrints/";
        File des = new File(screenShotLocation + imageName + "_" + timeInFormat + ".png");
        FileUtils.copyFile(src, des);
        snapShot = des.toString(); //not needed as we are not using, returning int i
        i++; //i counts the no of times control coming into getScreenShot method 
        System.out.println(i);
    } catch (Exception e) {
        System.out.println("The ScreenShot could not be taken\n" + e);
        e.printStackTrace();
    }
    return i;
}

    int screen = getScreenShot();
  • 现在，您可以从
    main（）
    /
    @Test
    调用
    getScreenShot（）
    ，如下所示：

    screen = getScreenShot();

    TakesScreenshot ts = (TakesScreenshot) driv;
File src = ts.getScreenshotAs(OutputType.FILE);

    public int getScreenShot() {

    String snapShot = null; //possibly not needed, we are returning int i
    int i = 0;
    String imageName = "blank";
    try {
        Calendar cal = Calendar.getInstance();
        Date currentTimeStamp = cal.getTime();
        String timeInFormat = formater.format(currentTimeStamp);
        TakesScreenshot ts = (TakesScreenshot) driv;
        File src = ts.getScreenshotAs(OutputType.FILE);
        String screenShotLocation = System.getProperty("user.dir") + "/screenPrints/";
        File des = new File(screenShotLocation + imageName + "_" + timeInFormat + ".png");
        FileUtils.copyFile(src, des);
        snapShot = des.toString(); //not needed as we are not using, returning int i
        i++; //i counts the no of times control coming into getScreenShot method 
        System.out.println(i);
    } catch (Exception e) {
        System.out.println("The ScreenShot could not be taken\n" + e);
        e.printStackTrace();
    }
    return i;
}

    int screen = getScreenShot();

您可以在

中找到详细的讨论，请尝试此代码我希望您能解决此问题

public String captureScreen(String fileName) {
if(fileName =="") {
    fileName="Screenshot";  }

File destFile=null;
Calendar calendar =Calendar.getInstance() ;
SimpleDateFormat formater= new SimpleDateFormat("dd_MM_yyy_hh_mm_ss");
File srcFile=((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);

try {

     String reportDirectory= new File(System.getProperty("user.dir")).getAbsolutePath()+"./src/main/java/com/test/automation/Demo/screenshot/";
     destFile= new File((String)reportDirectory + fileName +"-" + formater.format(calendar.getTime())+ ".png");
     FileUtils.copyFile(srcFile,destFile );

    }
catch(IOException e) 
  {
    e.printStackTrace();
  }
   return destFile.toString();
}

是的，我使用了SimpleDateFormat Format=new SimpleDateFormat（“dd_-MM\u-yyy\u-hh\u-MM\u-ss”），它不能在同一秒内拍摄多个屏幕打印。现在我也在使用毫秒，即SimpleDateFormat Formatter=new SimpleDateFormat（“dd_-MM_-yyy_-hh_-MM_-ss.SSS”），它正在获取所有屏幕打印。非常感谢：）非常感谢你的努力和时间。。但现在我的函数正在工作，因为我还包括了毫秒SimpleDateFormat Format=new SimpleDateFormat（“dd_-MM_-yyy_-hh_-MM_-ss.SSS”），正如您所建议的，我删除了参数，并将图像名称改为“image_20_-04_-2018_-02_-27_-36.523.png”谢谢：）@RachitJain好消息！！！如果我的答案符合您的问题，请单击我的答案旁边的空心复选标记（位于VoteDown箭头下方）来输入答案，使复选标记变为绿色。
