Applitools Execution Cloud
The first self-healing test infrastructure
for open-source test frameworks
May 2023

2
Introducing Applitools Execution Cloud
• Execute your existing open-source based tests at scale
• Lightning fast
• Affordable
• Execute all your tests
• Test public as well as local apps
• Single platform for authoring and executing tests
• Self-healing for open-source test frameworks

3
Agenda
• Why cloud infrastructure?
• Functional testing at scale
• Cross device and browser testing
• Self healing
• Q&A

4
Why do we need to execute tests faster?
BEST IN CLASS
• Speed: 5-15 minutes per build
• Frequency: test every PR, multiple updates a day
• Coverage: Interaction logic, Business Logic, Cross Device &
Browser
LEADS TO
• Faster feedback to developers
• More features delivered to customers

5
Why test on cloud infrastructure?
• Modern apps require hundreds of tests to cover properly
• Fast execution requires reliable and scalable infrastructure
• Difficult build and maintain
• Scale
• Hosting
• OS, device & browser upgrades
• High availability
• Debugging
• Reporting & dashboarding
• Premium features: self healing, etc.
• Costs more than paying a lab provider

6
Fast functional testing
• Make sure interaction logic works
• Verify business logic by validating application output
• Best is class: a single browser is sufficient
• Keep the number of test runs to a minimum (speed, concurrency, and cost)
• Avoid every bug failing tests on multiple devices and browsers
• Negligible loss of coverage
• It is extremely unlikely that
• Clicking a button will work on one browser but not on another
• The application output will be computed correctly on one browser but not on another
• Unless the UI is distorted on that specific device or browser
• That’s a different use case. We’ll cover it later.

8
Testing local apps behind the firewall
• Set the following environment variable
APPLITOOLS_TUNNEL = true
• Or using the browser capabilities
set ‘applitools:tunnel’ to true

9
Fast cross device and browser testing
• Verify that the UI renders application output correctly
• Across different devices, browsers and window sizes
• Different browsers are based on different layout engines
• Developers develop the app on a single dev machine
• Responsive design rules are prone to error
• Can only be effectively validated visually
• Hundreds of UI elements per page, dozens of properties per element
• Different property values per browser, device and screen size

Visual assertions advantages
• Enhances existing tests and
reduces the amount of test code by
up to 80%
• A single visual checkpoint for
complete visual and functional
coverage
• Catches unexpected defects
• Does not break when the UI
changes
• No coding skills required to
maintain validation logic

Universal framework support

SCM integrations (Github and others)

21
Self-healing locators
• Element locators often break when the UI changes
• driver.findElement(By.css('#navigation-right > a’));
• This is the primary cause for delaying test feedback and for
high test maintenance overhead
• Self healing finds an element even if its locator breaks
• The test can continue running
• The broken locator can be fixed later (or never)

22
How does self-healing work?
• Every time we find an element
• Capture hundreds of data points about the element
• All attributes, location in hierarchy, details of ancestor and neighbor elements
• Store data in a DB using the locator as key
• When we can’t locate an element using a given locator
• Retrieve information from the DB using the failed locator
• Use proprietary algorithms to find the element based on that information
• If successful, update the DB and suggest a new locator in our dashboard
• Return the found element

23
What can we heal?
• We can find an element even if simultaneously
• Element properties change (e.g., ID, class, tag name, custom, etc)
• Text changes (clickable text, input value, label, placeholder)
• DOM position changes (hierarchy, position in list)
• Size and location changes
• Adaptive
• Implicitly wait for elements

24
When is self healing useful?
• Avoid test failures and test maintenance following UI changes
• UI pages that frequently change
• Poor locator authoring skills
• Apps with weak locators
• Apps with dynamically generated UI (dynamic ids)

25
Self-healing for open-source frameworks
• Self-heal your existing tests without changing a line of test code
• Use your preferred test framework
• No vendor lock-in
