When Protractor was officially deprecated, it wasn’t just the end of a tool—it was a wake-up call for teams relying on aging test infrastructure. At VaynerSystems, we recently started a strategic migration from Protractor to Playwright, modernizing our end-to-end (E2E) test suite for better speed, reliability, and maintainability. The results speak for themselves.
Why Protractor Had to Go
Protractor served its purpose in Angular-heavy projects, but its end-of-life status brought major drawbacks:
- ❌ No longer maintained - This means no new features, no security patches, and increasing incompatibility with evolving browser versions.
- 🧪 Stale test environment – Our Protractor setup was locked to Chrome v98, running on a Zalenium-based infrastructure, while the current version is Chrome v137. That's a 39-version lag—creating obvious test reliability and coverage risks.
- 🐌 Slow execution – Our tests became bloated and sluggish. As projects grew, feedback loops widened and CI pipelines slowed down.
It was time to move forward.
Enter Playwright: A Modern framework for E2E + API Testing
We selected Microsoft's Playwright as our new testing framework—and it didn’t take long to validate the decision. The tool offers a developer-friendly, fast, and powerful approach to browser automation.
Key advantages of Playwright:
- ⚡ Parallel execution & fast startup times
- 🧪 Support for all modern browsers (Chromium, Firefox, WebKit) out-of-the-box
- 🛠️ Built-in support for test retries, traces, and debugging
- 🌐 Integrated API testing capabilities to pair UI validation with backend verification
- 🧭 Modern async/await syntax and native TypeScript support for clean and maintainable test code
Numbers don’t lie: Playwright vs. Protractor
We began the transition by rewriting our three heaviest UI tests, combining API assertions with UI workflows. Here's the performance comparison:
| Test Suite | Protractor Execution Time (min) | Playwright Execution Time (min) |
|---|---|---|
| project.spec.ts | 12.2 | 5.3 |
| smoke.spec.ts | 13.2 | 4.3 |
| market-case.spec.ts | 8.0 | 4.2 |
That’s 2x to 3x faster execution, with significantly better stability and traceability.
Additionally, Playwright's trace viewer and auto-wait mechanisms have reduced flakiness, saving hours of debugging every sprint.
Seamless API integration
One of the biggest wins in this migration was combining UI and API verifications in a single test suite using Playwright’s native APIRequestContext.
This allows us to:
- Validate backend data directly before and after UI interactions
- Eliminate unnecessary UI steps when validating business logic
- Accelerate test execution by blending layers smartly
This unified strategy means faster, more reliable tests that give deeper insight into failures.
