Block Testing

If you are using variables in your block, make sure to mock relevant test values in the Variable Previews Values JSON panel in Block Settings before you get started. This will give your block something to reference for any used variable.
For preliminary test mid-development, use the editor preview combined with the console to iteratively to check your changes.
Try to ensure your block is working completely as expected in the editor preview before moving on. If using actions, make sure that interactions in the preview, result in actions being printed to the console. This means it’s working as needed for the app to accept it.
If your app is not live, you can immediately place you block on a page & test via TestFlight or APK. If you need either make sure to reach out to your Tapcart point of contact. If you have an Apple Developer account, you can get a TestFlight run on your own app. If you don’t have an Apple Developer account, you can also receive an APK file to test on Android. If you don’t either, you will be placed on a one-off test app by Tapcart, where you will receive a generic app to test your block on. They may require additional setup.
If your app is live, it’s recommended to place the block on the product page, and to conditionally tag the block to show only a single product. This diverts traffic from the block, while allowing you to use it in production. Make sure to use a test product, or one that receive little traffic & that can only be found in search.
While testing your block, make sure to force quite & restart the app to receive any recent changes. Occasionally, a prior custom block may cache to your local device, leaving the block unable to receive new updates. To bypass this you can deleter & reinstall the app, or wait 2-3 hours for a full reset.
