Self-Healing Automation with Healenium


Request for price


Length: 5 day (40 hours)

 

This course is an advanced specialization for automation engineers. It moves beyond standard scripting to teach you how to build resilient, maintenance-free test suites.

You will learn the internal mechanics of Healenium’s LCS (Longest Common Subsequence) algorithm, how to set up the Healenium Backend (Docker), and how to wrap standard WebDrivers into Self-Healing Drivers. The course also covers advanced reporting where the system shows you exactly what it "healed," its confidence score, and screenshots of the fix

Selenium Proficiency: You must be comfortable writing scripts in Java (or Python/C#) using Selenium WebDriver.

Core Java & Maven: Understanding of dependency management and basic Page Object Model (POM) design.

Docker Basics: Ability to run simple commands (like docker-compose up) as Healenium’s backend services are containerized.

Database Fundamentals: Basic knowledge of PostgreSQL (Healenium's storage layer for element metadata).

Automation Engineers (SDETs): Tired of spending 30–50% of their time fixing broken locators every sprint.

QA Leads: Who need to improve the ROI of automation by reducing maintenance costs.

DevOps Engineers: Looking to stabilize CI/CD pipelines that frequently fail due to "flaky" UI tests.

Tech Architects: Evaluating AI/ML tools to modernize their company's testing stack.

Course objectives

After completing this course, students will be able to:

    • Eliminate NoSuchElementException: Stop scripts from failing immediately when a developer changes an ID or CSS class.
    • Architect Healenium Infrastructure: Deploy the Healenium backend using Docker and integrate it with PostgreSQL.
    • Implement Self-Healing Drivers: Transition existing frameworks by wrapping standard drivers with SelfHealingDriver.create(delegate).
    • Analyze Healing Reports: Use the Healenium Web UI to review healed locators, confidence scores, and success rates.
    • Master the IDEA Plugin: Use the IntelliJ plugin to update your source code with healed locators in a single click.
    • Scale with Appium & Selenide: Apply self-healing logic to Mobile automation and wrapper frameworks like Selenide.

Course outlines

    • Phase 1: Understanding the AI Engine
      • The "Brittle Locator" Problem: Why traditional automation fails in Agile/DevOps.
      • Healenium Architecture: How the Proxy, Backend, and Database interact.
      • The Healing Algorithm: Deep dive into Tree comparison and heuristic matching.
    • Phase 2: Infrastructure & Setup
      • Docker Implementation: Running the docker-compose.yaml to spin up Postgres and the Healenium Backend.
      • Maven Integration: Adding healenium-web and hlm-backend dependencies.
      • Configuration: Setting up the healenium.properties file for threshold and recovery settings.
    • Phase 3: Writing Self-Healing Scripts
      • The Wrapper Method: Converting a ChromeDriver into a SelfHealingDriver.
      • Page Object Model Integration: Making your Page Factory or @FindBy annotations self-healing.
      • Simulating UI Changes: A hands-on lab where we intentionally break a website's IDs to watch Healenium fix them in real-time.
    • Phase 4: Reporting & Maintenance
      • Healenium Web UI: Reviewing the "Healing Results" dashboard.
      • The One-Click Fix: Using the IntelliJ IDEA Plugin to permanently update your Java files.
      • Parallel Execution: Running self-healing tests in parallel on Selenium Grid or Selenoid.
    • Phase 5: Advanced Scenarios
      • Iframe & Shadow DOM: Handling complex web structures with Healenium.
      • Appium Integration: Applying self-healing to Android and iOS mobile apps.
      • CI/CD Pipeline: Integrating Healenium into Jenkins or GitHub Actions.
