Code coverage is not instrumenting React components (React Native)

z7edge opened this issue · comments

I am using Detox with Cucumber for BDD test report. All test feature is working fine. Then I installed nyc plugin for generating detailed test coverage report but that is not instrumenting React components (such as App.js).
While using with jest it is working as expected but for some technical reasons we have to use it with Cucumber test.

Expected Behavior

Instrumentation of all the React components should happen.

Observed Behavior

All the React functional component code is going in Uncovered Line column of the coverage report.

Troubleshooting steps

  • still occurring when I put cache: false in my nyc config
