An application only variant of the karma builder found within the @angular-devkit/build-angular package is now available within the @angular/build package as @angular/build:karma. This builder will only use the application builder found within @angular/build and does not provide the builderMode option as application would be the only valid value. Testing behavior is effectively equivalent to using the @angular-devkit/build-angular:karma builder with the builderMode option set to application. However, several options have been adjusted:

  • builderMode was removed
  • fileReplacements legacy structure (src/replaceWith) removed
  • polyfills only accepts an array of strings
  • loader has been added
  • define has been added
  • externalDependencies has been added
  • sass sub-option for stylePreprocessorOptions has been added

From an implementation perspective, the test finding logic and the application builder integration have been moved to the @angular/build package and reused by the @angular-devkit/build-angular package via the private export of @angular/build.

The new builder should be added in https://github.com/angular/angular-cli/blob/main/packages/angular/cli/lib/config/workspace-schema.json as well.

An `application` only variant of the `karma` builder found within the
`@angular-devkit/build-angular` package is now available within the
`@angular/build` package as `@angular/build:karma`. This builder will
only use the `application` builder found within `@angular/build` and
does not provide the `builderMode` option as `application` would be the
only valid value. Testing behavior is effectively equivalent to using the
`@angular-devkit/build-angular:karma` builder with the `builderMode`
option set to `application`. However, several options have been adjusted:
* `builderMode` was removed
* `fileReplacements` legacy structure (`src`/`replaceWith`) removed
* `polyfills` only accepts an array of strings
* `loader` has been added
* `define` has been added
* `externalDependencies` has been added
