Article Summary

E2E testing on mobile is notoriously slow and flaky. Expo just partnered with Moropo to change that equation for React Native developers.

Expo has integrated Moropo, a cloud-based E2E testing platform, to help developers run fast, reliable tests without the usual infrastructure headaches. The solution targets the biggest pain points in mobile testing: speed, stability, and setup complexity.

Key Takeaways

Critical Insight

Expo developers can now run E2E tests 10x faster on real devices without managing any infrastructure, starting with a free tier.

The article reveals how Moropo's architecture solves the flakiness problem that plagues most mobile E2E testing frameworks.

About This Article

Problem

Mobile E2E testing usually means developers have to set up and manage devices locally. This infrastructure is complex and hard to get right, which makes reliable testing difficult.

Solution

Expo partnered with Moropo to use their cloud platform for running tests. Now you can run tests on real devices in parallel without managing any local setup.

Impact

Tests run 10x faster than the old way. Expo projects get a free tier with 100 test minutes each month.
