Applitools Eyes supports a wide variety of popular web, mobile and desktop test automation frameworks and we're constantly working on supporting additional ones. If your framework is not listed below, you can still visually validate your app by obtaining screenshots yourself and using one of the screenshot SDKs to validate them.
The Applitools Eyes Screenshot Ruby SDK allows you to easily add visual checkpoints to your Ruby images tests. It takes care of images given by the user, sending them to the Eyes server for validation and failing the test in case differences are found.
Applitools Eyes reports differences by comparing screenshots of your application with baseline images that define the expected appearance of the application at each step of the test. The user should specify the environment (OS and application under test), and the Eyes SDK will automatically set the viewport size based of the size of the image being tested. It will then compare the screenshots against baseline images that are specific to that environment. The first time you run a test in a given environment, its screenshots will be automatically saved as its baseline. Starting from the second run onward, you always have a baseline to compare against.
The test below is a simple Ruby program that visually validates an image from Applitools' homepage. It consists of a single visual checkpoint, The first time you run this test a new baseline will be created, and subsequent test runs will be compared to this baseline. If any screenshot mismatch its baseline image in a perceptible way, eyes.close will throw a DiffsFoundError which includes a URL that points to a detailed report where you can see the detected differences and take appropriate actions such as reporting bugs, updating the baseline and more.
Before running the test, make sure to set the API key that identifies your account in the environment variable APPLITOOLS_API_KEY or directly assign it to the eyes.api_key method. You can find your API key under the user menu located at the right hand side of the test manager toolbar. If you don't yet have an account create it now to obtain your key.
require 'eyes_images' require 'logger' require 'open-uri' require 'chunky_png' eyes = Applitools::Images::Eyes.new # Initialize the eyes SDK and set your private API key. eyes.api_key = 'YOUR_API_KEY' eyes.log_handler = Logger.new(STDOUT) image_url = 'https://applitools.com/images/tutorials/applitools_hero.png' image_file = open(image_url) image = ChunkyPNG::Image.from_file(image_file) eyes.test(app_name: 'Eyes Images SDK', test_name: 'Applitools Hero') do # Visual validation. eyes.check_image(image_bytes: image.to_blob, tag: "test") eyes.check_region( image_bytes: image.to_blob, region: Applitools::Region.new(75, 175, 465, 75), tag: 'Main Text' ) end
Congratulations! You've successfully run your first visual UI test with Applitools Eyes! A detailed
report is ready for your inspection at the
