<form (ngSubmit)="onSubmit()" #testForm="ngForm" ngNativeValidate>
  <input type="text" id="test1" name="test1" [(ngModel)]="test" required>
  <input type="text" id="test2" name="test2" [(ngModel)]="test" [required]="true">
  <input type="text" id="test3" name="test3" [(ngModel)]="test" [attr.required]="true">
