Detox vs Happo.io: What are the differences?

Detox: Gray box end-to-end testing and automation library for mobile apps. High velocity native mobile development requires us to adopt continuous integration workflows, which means our reliance on manual QA has to drop significantly. It tests your mobile app while it's running in a real device/simulator, interacting with it just like a real user; Happo.io: Cross-platform, cross-browser screenshot testing for modern user interfaces. Happo is a visual regression testing tool. It hooks into your CI environment to compare the visual appearance of UI components before and after a change. Screenshots are taken in different browsers and across different screen sizes to ensure consistent cross-browser and responsive styling of your application.

Detox and Happo.io can be primarily classified as "Testing Frameworks" tools.

Some of the features offered by Detox are:

• Automatically Synchronized
• Test Runner Independent
• Debuggable

On the other hand, Happo.io provides the following key features:

• No more manual parsing of CSS
• See the effects of changes directly
• Test individual components in isolation
