Tests don't run in Angular 16 using Jasmine/Karma

Reproduce the failure with ng test using the Angular CLI, Node, and TypeScript versions listed in the issue. Start by examining @ngtools/webpack/src/ivy/index.js and the project's tsconfig configuration; done means Angular 16 tests run without the reported unknown-token or missing-compilation error.

Command

test

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

15

Description

The project compiles well, and the tests worked in version 15 of Angular. After running ng test I am receiving the following error:

ng-virtual-main.js!=!data:text/javascript;base64 ...Unknown string like token - Error: Module build failed (from ./node_modules/@ngtools/webpack/src/ivy/index.js): ...Unknown string like token s missing from the TypeScript compilation. Please make sure it is in your tsconfig via the 'files' or 'include' property.
