Move from using async to waitForAsync #22154
Description
CLI
Angular is deprecating async() in favor of waitForAsync() the CLI should change this in the generated output spec file.
Example:
import { async, ComponentFixture, TestBed } from '@angular/core/testing';
import { IonicModule } from '@ionic/angular';
import { LoginPage } from './login.page';
describe('LoginPage', () => {
let component: LoginPage;
let fixture: ComponentFixture<LoginPage>;
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [LoginPage],
imports: [IonicModule.forRoot()],
}).compileComponents();
fixture = TestBed.createComponent(LoginPage);
component = fixture.componentInstance;
fixture.detectChanges();
}));
it('should create', () => {
expect(component).toBeTruthy();
});
});
Should be:
import { waitForAsync, ComponentFixture, TestBed } from '@angular/core/testing';
import { IonicModule } from '@ionic/angular';
import { LoginPage } from './login.page';
describe('LoginPage', () => {
let component: LoginPage;
let fixture: ComponentFixture<LoginPage>;
beforeEach(waitForAsync(() => {
TestBed.configureTestingModule({
declarations: [LoginPage],
imports: [IonicModule.forRoot()],
}).compileComponents();
fixture = TestBed.createComponent(LoginPage);
component = fixture.componentInstance;
fixture.detectChanges();
}));
it('should create', () => {
expect(component).toBeTruthy();
});
});
