PVS‑Studio — Automated E2E Testing System

Project Context

PVS‑Studio is a well‑known static analyzer for C/C++/C#/Java. The corporate website is a business‑critical asset: product presentation, trial download, license purchase, support, documentation, and content.

Any site bug directly impacts sales and reputation.

Goal

Build a full E2E automation system that:

• Covers 100% of critical user journeys
• Prevents regressions on site updates
• Integrates into CI/CD
• Enables quick pre‑release checks
• Reduces manual toil on routine checks

Solution

Architecture

• Page Object Model: separation of test logic and page elements, reusable components, centralized locators, easier maintenance.
• Project structure: pages/, components/, tests/, fixtures/, config/, utils/.

Coverage

Business‑critical flows:

• Trial download forms
• Purchase flow (cart + checkout)
• Navigation across core sections and menus
• Search (docs and articles)
• Contact and support forms
• Internationalization (EN/RU/JP etc.)

Technical checks:

• Broken links (404)
• Static assets loading
• Responsive checks (desktop/tablet/mobile)
• JS components behavior
• Form validation and error handling

Stack

Selenium WebDriver (cross‑browser, headless in CI), Python + pytest (fixtures, parametrization, parallel runs), Docker for reproducibility, CI pipelines for triggers and artifacts, screenshots on failure.

Results

Business effects: prevented bugs in purchase and download flows, faster releases, lower risk, time saved for QA.

Technical: robust, low‑flakiness suite; CI‑integrated; scalable architecture.

Metrics: ~15–20 min full run (parallel), >95% green without code changes, coverage across core pages/forms, Chrome/Firefox/Edge.

Takeaways

Automation is a system, not “some tests”: POM for maintainability, CI for continuous quality, Docker for reproducibility, and business‑outcome‑first priorities.
