Give some tries and adjust the maxDistanceAllowed to your needs. consistent and the method returns TRUEĭidn't test the C# code, but it should give you the idea. Visit before installing to help you decide the best version. I am am still figuring how to use image magick with this configuration. I have configured Selenium to run with junit core in eclipse. Basically I want to automate comparison of screenshots (new with old) of web applications. With Magick.NET you can use ImageMagick without having to install ImageMagick on your server or desktop. 1 Can somebody guide as to how can I use image magick or jmagick in designing automation visualization testing. If the actual distance is less than the max allowed, the pixel is ImageMagick is a powerful image manipulation library that supports over 100 major file formats (not including sub-formats). This does not mean you cannot use Selenium for your project rather, it means you will need to use Selenium to capture the images and something other than Selenium to compare the images. You will need some other mechanism to do that. 0:00 / 4:23 Visual Test Automation ImageMagick and Selenium SW Test Academy 130 subscribers 375 views 1 year ago Visual Test Automation ImageMagick and Selenium You can find all details on. Public bool isPixelConsistent(Color pixel1, Color pixel2)įloat distanceSquared = (pixel1.R - pixel2.R)*(pixel1.R - pixel2.R) + (pixel1.G - pixel2.G)*(pixel1.G - pixel2.G) + (pixel1.B - pixel2.B)*(pixel1.B - pixel2.B) 2 Answers Sorted by: 1 I have used for image compare. Selenium does not provide a way to compare images. Square of the distance, used in calculations.įloat maxD = maxDistanceAllowed * maxDistanceAllowed To improve performance a little, do not calculate the square root but check the squares of the distances // Maximum color distance allowed to define pixel consistency. However, if you don't have a proper development environment or if you're anxious to get started, download a ready-to-run Linux or Windows executable. I think you can check each pixel with a common Euclidean Distance. Download Linux Binary Release Mac OS X Binary Release iOS Binary Release Windows Binary Release You can install ImageMagick from source. Use an image format that does not create artifacts (like BMP or PNG) then you can do a per-pixel comparison.
