About This Project

The Purpose

Selenium + Java remains the dominant stack in financial services, insurance, energy, and enterprise IT. These organisations have large existing WebDriver codebases and hiring pipelines tuned for Java fluency.

This is Stack 3 of the Cross-Stack Series — the same QA Lab target tested with different frameworks to enable direct, evidence-based comparison. The framework demonstrates enterprise-grade Java automation practices without advocating for this stack over modern alternatives.

The author’s preferred stack for new projects is Playwright. This framework exists to prove cross-stack fluency — the ability to be effective in Java environments without requiring a full stack migration.

Architecture Constraints

Every decision reflects real enterprise requirements:

  • ThreadLocal<WebDriver> — parallel-safe, 4 concurrent threads in CI
  • Page Factory + @FindBy — zero driver.findElement() in test classes
  • WebDriverWait throughout — no Thread.sleep() anywhere in the diff
  • @DataProvider(parallel=true) — data-driven tests without manual loops
  • ITestListener — ExtentReports auto-populated, no manual flush()
  • WebDriverManager — runtime chromedriver resolution, zero binary commits
  • @AfterMethod(alwaysRun=true) — guaranteed driver.quit() even on failure
  • Checkstyle 10 — code style enforcement expected in enterprise Java teams

Test Coverage

13 QA Lab UI sections covered across 48 test classes. Same automation surface targeted in every Cross-Stack Series framework.

Buttons
Click states, disabled assertion
Forms
Validation, field interaction, submit
Input Fields
Text, number, date, search, URL
Checkboxes
Check/uncheck, disabled state
Radio Buttons
Selection, mutual exclusivity
Dropdowns
Select class, single & multi-select
Tables
Cell content, row count, edit action
Alerts & Modals
Open, confirm, cancel, dismiss
Dynamic Visibility
Checkbox-triggered panel reveal
Async Buttons
Loading → success/error transitions
IFrames
switchTo().frame() / defaultContent()
Drag & Drop
Actions class mouse simulation
Slider
Actions.dragAndDropBy()
