Reducing screenshot taking time on selenium

Crop the screenshot

One way of getting smaller sized screenshots (other than using various file formats) is changing the size of the screenshot: you can take a screenshot of a web element (or a region of a page) that is of special interest to you.

Try the following (you will need to use the BufferedImage class):

@Testpublic void test() throws InterruptedException, IOException {    driver.get("https://google.com");    driver.findElement(By.name("q")).sendKeys("automation test");        long before = System.currentTimeMillis();    File srcFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);    Point p = element.getLocation();    int width = element.getSize().getWidth();      int height = element.getSize().getHeight();    BufferedImage img = ImageIO.read(scrFile);    BufferedImage elementScreenshot = img.getSubimage(p.getX(), p.getY(), width, height);    //NOTE: the line above will crop the full page screenshot to element dimensions, change width and height if you wish to crop to region    Image.write(elementScreenshot, "png", scrFile);    FileUtils.copyFile(srcFile, new File("/Users/name/localpath/test.png"));    long after = System.currentTimeMillis();    System.out.println(after-before);}

The problem is transferring the file over the wire most likely. IT might also be in the creation of the file.

I would suggest trying with the Base64 output to see if that reduces the transfer time:

String screenshotAsBase64String = ((TakesScreenshot)driver).getScreenshotAs(OutputType.BASE64);
