I should have raised this last night! When doing my testing I noticed the src folder in ngtsc doesn't get included in the npm release anymore, causing the error above.

When doing local testing, I had to manually copy that folder (ngtsc/src) into the node_modules jest-preset-angular/build/ngtsc folder.

Using yarn link or npm link during local testing works because it symlinks the directory containing the correct files, but npm publish and yarn publish are not including that folder.

I'm not sure why it's no longer being included in the published bundle, but that is the cause of the error, and it'll likely cause problems for any consumer of the package.

Seem like this line https://github.com/thymikee/jest-preset-angular/blob/main/.npmignore#L6 did a recursive search and caused the problem.

I'm encountering this as well.

[michaelfaith]

Thanks for the quick turnaround.

11.0.0-rc.1 was out, the problem should be fixed now

[michaelfaith]

Can confirm. This fixed the issue we were seeing. But I'm now seeing another related to Angular Material initialization:

Test suite failed to run

    ReferenceError: Cannot access 'MatButtonToggle' before initialization

       7 | import { ComponentFixture, TestBed } from '@angular/core/testing';
    >  8 | import { MatButtonToggleModule } from '@angular/material/button-toggle';
         | ^
       9 | import { MatIconModule } from '@angular/material/icon';

      at Object.<anonymous> (src/app/component-demos/button-toggle-demo/button-toggle-demo.component.spec.ts:8:1)

Guess I'll open a new issue for it.

It's happening with several Angular Material component modules.
