I have an angular CLI project set up. I've made a form that uses angular material components, like <md-card>
.
I'm just starting out with writing my first Karma/Jasmine unit test, following the steps in the angular docs.
This is my component template:
<md-card [ngClass]="'dialog-card'">
<md-card-title [ngClass]="'dialog-title'">
{{title}}
</md-card-title>
<md-card-content>
<form (ngSubmit)="login()" #loginForm="ngForm">
<md-input-container class="md-block">
<input md-input [(ngModel)]="user.email"
name="userEmail" type="email" placeholder="Email"
ngControl="userEmail"
required>
</md-input-container>
<br>
<md-input-container class="md-block">
<input md-input [(ngModel)]="user.password"
name="userPassword" type="password" placeholder="Password"
ngControl="userPassword"
required>
</md-input-container>
<br>
<tm-message msgText="Wrong username or password" *ngIf="showError"></tm-message>
<br>
<button md-button type="submit" [disabled]="!loginForm.form.valid">Login</button>
<p (click)="openForgotPasswordModal()">Forgot Password?</p>
</form>
</md-card-content>
This is my karma spec:
import { ComponentFixture, TestBed } from '@angular/core/testing';
import { By } from '@angular/platform-browser';
import { DebugElement } from '@angular/core';
import { MaterialModule, MdDialogRef, MdDialog } from '@angular/material';
import { FormsModule } from '@angular/forms';
import { RouterTestingModule } from '@angular/router/testing';
import { TmLoginComponent } from './tm-login.component';
import { TmMessageComponent } from '../../shared/components/tm-message.component';
import { UserAuthenticationService } from '../login/user-authentication.service';
describe('TmLoginComponent (inline template)', () => {
let comp: TmLoginComponent;
let fixture: ComponentFixture < TmLoginComponent > ;
let de: DebugElement;
let el: HTMLElement;
beforeEach(() => {
TestBed.configureTestingModule({
declarations: [TmLoginComponent, TmMessageComponent], // declare the test component
imports: [MaterialModule, FormsModule,
RouterTestingModule.withRoutes(
[{
path: 'login',
component: TmLoginComponent
}, ])
],
providers: [UserAuthenticationService],
});
fixture = TestBed.createComponent(TmLoginComponent);
comp = fixture.componentInstance; // TmLoginComponent test instance
// query for the title <h1> by CSS element selector
de = fixture.debugElement.query(By.css('.title'));
el = de.nativeElement;
});
it('should display original title', () => {
fixture.detectChanges();
expect(el.textContent).toContain(comp.title);
});
});
At this point, I'm just trying to run the basic unit test that the title is being displayed properly.
However, I'm getting a lot of material specific errors. Like
No provider for MdDialog.
I'm opening an md Dialog on clicking a link. THe code is in the (fairly long) .ts file, but that's not the issue here.
Where would I add MdDialog in the testbed? If I add it to providers, I get the error: "no provider for overlay". I don't know how to fix that.
Is there any way I can configure karma to include all material components at start?
Thanks.
Current technique calls for individual imports of Angular Material modules, as MaterialModule
is deprecated and was removed in 2.0.0-beta.11:
import {
MatButtonModule,
MatIconModule
} from '@angular/material';
Then add the same list as imports in the TestBed config:
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [ ... ],
imports: [
MatButtonModule,
MatIconModule,
...
],
providers: [ ... ]
})
.compileComponents();
}));
