# One Repo, One Strategy: Scalable Full-Stack Testing in a Monorepo World


- **Event:** World Congress 2026 North America

## Description

In large-scale systems, multiple teams, third-party integrations, and shared codebases can make testing feel impossible to coordinate. In this session, Bartosz and Pawel reveal how to bring order to that chaos using a unified full-stack testing strategy inside a monorepo architecture that powers both React and React Native applications.

They’ll show how to combine contract, integration, gRPC, API, and visual regression testing into one consistent framework that helps teams work independently without breaking each other’s services. You’ll learn how TypeScript and shared logic enable type-safe, scalable testing across platforms — and how this approach speeds up releases while reducing integration pain.

Expect practical patterns, real examples, and lessons learned from building test architectures that survive complex, distributed environments.
