Introducing E2E Tests to React Native Core

This episode of the React Native Show delves into the recent introduction of End-to-End (E2E) testing in RNTester. Join us as we unpack the thought process, technical considerations, and practical implementation of this new approach to testing in React Native.

This episode discusses

• The context and need for improvement in testing within the React Native ecosystem
• The goal and expected outcomes of introducing E2E testing
• The technical stack behind RNTester-E2E, including Appium and WebDriverIO
• The workflow of RNTester-E2E in practice and how it operates on every PR
• Future plans for RNTester-E2E, including community involvement, device farm integration, and screenshot testing

Mateusz Ulańczyk and Szymon Rybczak, the people directly involved in making this solution a reality, will give you a candid look at how E2E tests in RNTester can help reduce regressions, speed up releases, and ultimately lead to a more robust codebase. Tune in and enjoy a more stable codebase and more pleasant work!
