Advance Selenium Course

Lesson 1 • Selenium Ecosystem Overview

Covers Selenium WebDriver, Grid, and IDE roles within test automation. Positions each component so students choose the right tool for each scenario.

Lesson 2 • First Selenium Test Script

Writes, runs, and interprets a minimal browser automation script. Introduces the WebDriver API entry points used throughout the course.

Lesson 3 • Development Environment Configuration

Installs Java or Python, an IDE, and build tools needed for Selenium projects. Ensures a reproducible local setup before writing any test code.

Lesson 1 • Core Locator Strategies

Explains ID, name, class, tag, link text, and partial link text locators. Teaches when each strategy is most stable and maintainable.

Lesson 2 • Handling Dynamic and Complex Elements

Addresses dropdowns, checkboxes, radio buttons, and file uploads. Prepares students for UI patterns found in enterprise web applications.

Lesson 3 • Element Validation and Assertions

Verifies element visibility, enablement, and text content after interactions. Establishes assertion patterns reused in all subsequent test chapters.

Lesson 4 • XPath and CSS Selector Mastery

Builds complex XPath expressions and CSS selectors for dynamic elements. Covers absolute vs. relative XPath and CSS pseudo-classes.

Lesson 1 • Implicit Waits

Configures a global implicit wait timeout on the WebDriver instance. Explains scope, limitations, and interaction with explicit waits.

Lesson 2 • Fluent Waits and Custom Polling

Configures polling intervals and ignored exceptions in FluentWait. Handles scenarios where standard conditions are insufficient.

Lesson 3 • Understanding Test Flakiness

Diagnoses timing-related failures caused by asynchronous page behaviour. Motivates proper wait strategies as the primary fix for intermittent failures.

Lesson 1 • Alert and Dialog Handling

Accepts, dismisses, and reads text from browser alerts, confirms, and prompts. Prevents unhandled alert exceptions from blocking test execution.

Lesson 2 • Browser Windows, Tabs, and Frames

Switches context between windows, tabs, and iframes during test execution. Manages window handles and frame references for multi-context applications.

Lesson 3 • JavaScript Executor in Selenium

Executes JavaScript to scroll, click hidden elements, and modify DOM state. Fills gaps where the WebDriver API cannot reach native browser behaviour.

Lesson 4 • Actions Class for Complex Interactions

Uses the Actions API for mouse hover, drag-and-drop, and right-click operations. Builds action chains that mirror real user gestures.

Lesson 1 • Base Test Class and Reusable Utilities

Creates a base test class that manages driver lifecycle and shared configuration. Promotes DRY principles across the entire test project.

Lesson 2 • TestNG and pytest Fundamentals

Configures test runners, annotations, and assertion libraries for Selenium suites. Establishes the execution lifecycle that all subsequent patterns depend on.

Lesson 3 • Data-Driven Testing Techniques

Feeds test data from Excel, CSV, and JSON files into parameterised tests. Separates test logic from test data for scalable coverage.

Lesson 4 • Page Object Model Design

Encapsulates page locators and actions into dedicated class files. Reduces duplication and isolates UI changes to a single location.

Lesson 1 • Docker-Based Grid Deployment

Deploys Selenium Grid nodes as Docker containers for consistent environments. Introduces container scaling as a foundation for cloud grid usage.

Lesson 2 • Parallel Execution Configuration

Configures TestNG XML and pytest-xdist for parallel test runs against Grid. Measures and optimises thread counts for maximum throughput.

Lesson 3 • Setting Up a Local Grid

Launches Hub and Node processes locally and verifies the Grid console. Provides a controlled environment for learning parallel execution concepts.

Lesson 4 • Selenium Grid Architecture

Explains Hub, Node, and Router roles in Grid 4 architecture. Maps request routing from test code to the correct browser node.

Lesson 1 • Screenshot Capture on Failure

Captures full-page and element-level screenshots automatically on test failure. Embeds screenshots in reports for immediate visual diagnosis.

Lesson 2 • Logging Frameworks in Test Projects

Integrates Log4j or Python logging to capture runtime test events. Structured logs accelerate root-cause analysis after failures.

Lesson 3 • Test Maintenance and Refactoring

Identifies brittle locators, duplicated code, and outdated test data in existing suites. Applies systematic refactoring to restore suite reliability.

Lesson 1 • GitHub Actions for Test Automation

Writes YAML workflows that install dependencies and run Selenium tests on push events. Uses service containers to provide browser environments in CI.

Lesson 2 • CI/CD Pipeline Fundamentals

Explains pipeline stages, triggers, and artefact management relevant to test automation. Positions Selenium execution within a broader DevOps workflow.

Lesson 3 • Cloud Browser Platform Integration

Connects Selenium tests to cloud browser platforms for cross-browser and cross-OS coverage. Manages credentials, tunnels, and session concurrency.

Lesson 4 • Headless Browser Execution

Runs Chrome and Firefox in headless mode for faster CI execution without a display. Addresses rendering differences between headless and headed modes.
