Code Coverage is a metric to identify how the app has been tested locally and understand the different components which have been tested. While testing the app, with code coverage in place it is easy to identify the snippets of code that have been meet and also the snippets of code which have been missed from testing so that all cases of the app execution are tested thoroughly.
Code coverage for Freshworks Marketplace apps should meet 80% coverage with the different components to ensure the app code qualify and affirm that the app has been tested for all test cases.
Freshworks Developement Kit (FDK) is powered with IstanbulJS to test the app code and generate code coverage.
