Screen Shot and Image comparison testing using selenium

Screen Shot and Image comparison testing using selenium.In this video we are discussion about snap shot or screen shot and image or logo comparison testing using Selenium and ashot. We can compare company logo or any element image also using ashot . we have used extend reports for comparing actual and expected screenshot and weblement image in the report.We have not used hard assertion because we want to complete execution even though the comparison.

Can we validate the only some particular area if thats not an element?

public boolean compareImage(String ExpectedImage) throws IOException {
Screenshot shot = new
File file = new File(screenShotPath + ExpectedImage + ".png");
// System.out.println(file);
// ImageIO.write(shot.getImage(), "PNG", file);
// Getting Expected Image
BufferedImage expectedImg = ImageIO.read(file);
// Getting Actual Image
BufferedImage actualImg = shot.getImage();
// Image Comparison
ImageDiffer imgDiff = new ImageDiffer();
ImageDiff dif = imgDiff.makeDiff(expectedImg, actualImg);
return dif.hasDiff();
}



code to take webelement image and comparision

Screenshot logoElementScreenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(1000)).takeScreenshot(SeleniumUtil.getDriver(), logoElemnent);

File file = new File(screenShotPath + ExpectedImage + ".png");

BufferedImage expectedImg = ImageIO.read(file);
// Getting Actual Image
BufferedImage actualImg =
// Image Comparison
ImageDiffer imgDiff = new ImageDiffer();
ImageDiff dif = imgDiff.makeDiff(expectedImg, actualImg);
return dif.hasDiff();
