I'm making a CoreModule for my Angular apps by following the NgModule's guide but I get an Error: Can't resolve all parameters for CoreModule: (?).
when I use the module in a test.
Here's the CoreModule's code:
import {NgModule, Optional, SkipSelf} from '@angular/core';
@NgModule({})
export class CoreModule {
constructor(
@Optional() @SkipSelf() parentModule: CoreModule
) {
// Making sure this is not imported twice.
// http://ift.tt/2CX36Bd
if (parentModule) {
throw new Error(
CoreModule.name + ` is already loaded. Import it in the app's root module only.`);
}
}
}
And here's the test file's content:
import {TestBed, async} from "@angular/core/testing";
import {CoreModule} from "../../../core.module";
import {Injector} from "@angular/core";
describe(`Some test importing CoreModule`, () => {
beforeEach(async(() => {
TestBed.configureTestingModule({
imports: [
CoreModule,
]
});
}));
it(`should work`, () => {
TestBed.get(Injector);
});
});
What am I doing wrong?
Add the `--aot` flag to `ng serve` in your `start` script in `package.json`, e.g. `"start": "ng serve --aot",`.
