我有一个 Angular（当前为 @4.0.0）项目，我想为它介绍使用 Karma 和 Jasmine 的单元测试。
我已经设置了相应的karma.conf.js,spec-bundle.js和package.json. 但是当我运行时npm test，这就是控制台上的内容。测试脚本似乎没有被识别和运行。
这些是控制台上的警告，
我有一个spec简单测试的文件app.ts。
import { async, TestBed, ComponentFixture } from '@angular/core/testing';
import { By } from '@angular/platform-browser';
import { DebugElement } from '@angular/core';
import { App } from './app';
import { AuthorizationService } from '../service/security/authorizationService';
describe('App (templateUrl)', () => {
let comp: App;
let fixture: ComponentFixture<App>;
let de: DebugElement;
let el: HTMLElement;
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [App]
})
.compileComponents();
}));
beforeEach(() => {
fixture = TestBed.createComponent(App);
comp = fixture.componentInstance;
});
it('should display app title', () => {
fixture.detectChanges();
expect(comp.appTitle).toContain('Angular');
});
});
