Hi @pablobfonseca,
For the apps built with frontend frameworks, Freshworks CLI (FDK) cannot measure the code coverage yet since the actual code, and the compiled code varies.
We do not require 80% code coverage for the apps built with the frontend framework. Please follow the guidelines to attach the source within the app folder. The app will not be rejected for less than 80% code coverage.
Let us know if you still get stuck submitting the app to our Marketplace.
