An
applicationonly variant of thekarmabuilder found within the@angular-devkit/build-angularpackage is now available within the@angular/buildpackage as@angular/build:karma. This builder will only use theapplicationbuilder found within@angular/buildand does not provide thebuilderModeoption asapplicationwould be the only valid value. Testing behavior is effectively equivalent to using the@angular-devkit/build-angular:karmabuilder with thebuilderModeoption set toapplication. However, several options have been adjusted:builderModewas removedfileReplacementslegacy structure (src/replaceWith) removedpolyfillsonly accepts an array of stringsloaderhas been addeddefinehas been addedexternalDependencieshas been addedsasssub-option forstylePreprocessorOptionshas been addedFrom an implementation perspective, the test finding logic and the application builder integration have been moved to the
