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.

I have multiple secondary entrpoints. So I can't set sourceroot property on angular.json – Navarre

All your secondary entry points have the same root, so following your example in your angular.json you should set "sourceRoot": "projects/my-library" instead of "sourceRoot": "projects/my-library/src" that is what Angular sets as default – X

I got Mert's answer to work by also moving the test.ts file to the "project/my-library" level AND changing my tsconfig.spec.ts files from "src/test.ts" to "test.ts" – Julesjuley

It worked great for me. tnx man :) – Supplejack

After moving test.ts 1 level up, no need to change sourceRoot in angular.json, changing test/options/main path is enough. – Armistead

Actually, despite tests run, they don't reflect in the code coverage report. With or without changes to sourceRoot, only primary endpoint shows up in coverage. Any way to fix it? – Armistead
