End-to-End Testing
AI-driven E2E testing is no longer slow or brittle—it's the new quality standard. Discover why you should flip your testing pyramid.
Why Traditional Testing Falls Short
Most teams rely on unit and integration tests—but these check code in artificial ways real users never experience. Bugs appear where systems meet: user journeys, integrations, edge cases. Only E2E catches these boundary issues.
The Problem with Unit Testing
- Doesn't test user workflows
- Misses integration issues
- Create false confidence
Integration Testing: Not Enough
- Limited scope (focuses on subsystems)
- Artificial/mocked environments
- Ignores full user experience
E2E: Modern Quality Gate
E2E testing with Desplega simulates real user journeys across your entire app stack, validating complete workflows, integrations, timing, and UX behavior: the only true test of production readiness.
Why AI-Powered E2E Breaks the Old Tradeoffs
- Automatic test generation explores happy paths, errors, and boundaries
- Massive parallelism—run thousands of tests in minutes
- Tests "seed" between each other for full user journeys
- Self-healing computer vision & semantic selectors—no more brittle CSS
The New Testing Philosophy

Traditional: E2E was costly, slow, and brittle. Confidence & realism were directly opposite to each other.

AI-Era: E2E is primary, scalable, fast, and maintained by AI—covering real user journeys and UX realism.
Modern E2E = Primary Quality Gate
- Fast enough to run on every commit
- Scalable to thousands of test flows
- Maintained automatically by AI
- Comprehensive—now covers what matters for your business
Business Impact
- Ship with real confidence: app works for users, not just in isolation
- Deploy faster, reduce incidents, and free up engineering time
- Platform covers the bulk of automation needs—no staff bloat
How to Rethink Testing
- E2E tests as foundation: Rely on thousands of automatically-generated E2E flows for confidence in real user journeys.
- Add integration tests: Use for subsystems that need strict/deterministic behavior.
- Retain unit tests: Valuable for complex business logic or algorithms in isolation.
