我有以下组件代码:
<form name="form" (ngSubmit)="f.form.valid && login()" #f="ngForm" novalidate>
<div class="form-group" >
<input type="text" class="form-control" name="username" [(ngModel)]="model.username" #username="ngModel" required />
<input type="password" class="form-control" name="password" [(ngModel)]="model.password" #password="ngModel" required />
</div>
<div class="form-group">
<button type="submit" class="btn btn-primary margin-top-10 no-shadow full-width"><span class="text-uppercase">{{ 'login' | translate }}</span></button>
</div>
</form>
我尝试了下面的代码,但没有工作,总是得到失败的结果。
it('test invalid', () => {
const hostElement = fixture.nativeElement;
const username: HTMLInputElement = hostElement.querySelector('input[name="username"]');
username.value = 'jhon';
username.dispatchEvent(new Event('input[name="username"]'));
fixture.detectChanges();
let form = component.f.form.controls;
expect(form.username.invalid).toBe(false);
});
单元测试是否有任何建议代码?
