Question 1 of 5

• A component re-renders on every keystroke.
• Very large images decoded and drawn for small views, or deeply nested views with shadows.

• Assert that the component’s internal setDraft was called with a specific object.
• Find the input by its testID input-2 and read its props.value.
• Type into the field labelled “Distance (km)”, press the “Save” button by role, and expect onSave to receive 8.4.

Question 3 of 5

• Production builds can differ from development and preview; always install and test the actual release build before submitting.
• EAS Build is unreliable and you should build locally.
• The stores modified the binary during upload.

Question 4 of 5

• Updates take a week to propagate.
• Preview builds can’t receive updates at all.
• Preview builds listen to the preview channel, so they only get updates published there.
• The runtime version must be raised for every update.

Question 5 of 5

• Publish an eas update to production; users will download the module.
• Publish an update and ask users to restart twice.
• Keep the same version so existing updates still apply.
• Raise version, make a production build, submit it for review and release it; updates for 1.3 then target the new runtime version.
