1/ Your component screenshot tests are all green, but your app might still have visual issues.

Both component and screen tests share the same goal, improving visual quality, but they serve different purposes:

• A component test verifies one building block in isolation.
• A screen test verifies how those blocks live together: placement, padding, alignment, and how everything looks across phones, foldables, and tablets.

2/ A button that is perfect alone can have a wrong padding or placement.

Testing components in isolation cannot catch what only exists between elements.

One thing to try this week:
Add screenshot tests to your core screen. Check two font scales and both color modes (light and dark).

3/ Do you have screenshot test your screens, components, both, or not yet?

P.S: I recently published "Mastering Android Screenshot Testing," a hands-on guide to improving your app's visual quality.
