Angular library secondary entrypoint test code coverage problem

Question

I am using angular library with secondary entrypoint My library folder structure is

• my-library
  • secondary-entrpoint 1
    • service 1
  • secondary-entrypoint 2
    • service 2
  • src

And I used this command ng test my-library --code-coverage

The secondary entry points' service test doesn't execute.

Then I tried, changing "test.ts" context path('./') with '../' which is under the src folder. Tests were executed but code coverage doesn't create.

How can I execute tests for a secondary entry point?

Answer 1

That is because the source root of your project is pointing to projects/your-library/src and when running tests it does not take into account the other entry points.

To fix this just change the sourceRoot property in your "angular.json" file to projects/your-library, everything else should still work fine.
