请注意，它使用delcare namespace和全局declare function语句。这意味着此d.ts文件可以通过/// <reference path="..." />语句进行修改。
现在我使用新的明亮且有光泽的 Angular 2 以及 TypeScript 2.0 应用程序，我不想使用旧的打字，而是我我想使用新的@types方法。即我没有使用d.ts语句引用/// <reference path="..." />个文件，而是使用import语句，但这种方法不适用于jasmine.d.ts中声明的全局变量。
那么我如何导入在jasmine的d.ts文件中声明的单个全局声明，同时考虑到我只能遵守它，即我无法改变写入的真正的茉莉花代码JS。
以下是我的样本测试：
/// <reference path="../@types/jasmine/index.d.ts" />
import { By } from '@angular/platform-browser';
import { TestBed } from '@angular/core/testing';
import { AppComponent } from './app.component';
//////// SPECS /////////////
/// Delete this
describe('Smoke test', () => {
it('should run a passing test', () => {
expect(true).toEqual(true, 'should pass');
});
});
describe('AppComponent with TCB', function () {
beforeEach(() => {
TestBed.configureTestingModule({declarations: [AppComponent]});
});
it('should instantiate component', () => {
let fixture = TestBed.createComponent(AppComponent);
expect(fixture.componentInstance instanceof AppComponent).toBe(true, 'should create AppComponent');
});
it('should have expected <h1> text', () => {
let fixture = TestBed.createComponent(AppComponent);
fixture.detectChanges();
let h1 = fixture.debugElement.query(el => el.name === 'h1').nativeElement; // it works
h1 = fixture.debugElement.query(By.css('h1')).nativeElement; // preferred
expect(h1.innerText).toMatch(/angular 2 app/i, '<h1> should say something about "Angular 2 App"');
});
});
有没有办法摆脱/// <reference path="../@types/jasmine/index.d.ts" />并导入jasmine的d.ts全局声明（例如it，describe，{{1}使用expect
import语句方法
答案 0 :(得分：1)
有没有办法摆脱///
如果文件包含在编译上下文中，则不需要引用标记，例如在tsconfig.json https://basarat.gitbooks.io/alm/content/config/tsconfig.html
中使用include
