Section 1: Page Object Model

POM centralizes object repositories and abstracts locator updates cleanly.

Section 2: Playwright Auto-wait

Playwright performs actionability checks prior to issuing execution events.

22. Interactive Tabs in a Box

Selenium 4 supports bi-directional DevTools protocol and relative locators.

Playwright runs over native WebSockets with built-in network tracing.

Cypress operates directly within run loop execution contexts.

API Testing Sandbox

Mock HTTP endpoints for Rest-Assured, Postman, and Playwright API automation practice.

GET /api/users

Test pagination params, JSON query filters, and validate response status 200 OK.

POST /api/auth/login

Practice OAuth token extraction, Bearer Authorization headers, and validate status 201 Created.

PUT & DELETE /api/products/:id

Perform full resource updates, payload serialization, and verify status 204 No Content.

Git Version Control Lab

Practical Git workflows, branching strategies, rebase operations, and merge conflict resolution guides.

🌿 Branching & Merging

git checkout -b feature/login, git merge --no-ff, and trunk-based development workflows.

⚠️ Conflict Resolution

Learn how to read conflict markers (<<<<<<< HEAD) and safely resolve overlapping commits.

📦 Stashing & Rebasing

Keep a clean commit history with git rebase -i HEAD~3 and temporary uncommitted state preservation.

CI/CD Automation Pipelines

Continuous Integration and Continuous Deployment patterns for test automation suites.

⚙️ GitHub Actions

Setup headless test runs on pull requests with YAML triggers, matrix builds, and badge status updates.

🏗️ Jenkins Declarative Pipelines

Construct multi-stage automation triggers: Checkout -> Build -> Headless Test Execution -> Allure Reporting.

🐳 Docker Grid Execution

Containerize Selenium Hub with Chrome/Firefox nodes to achieve parallel, isolated automated test runs.
