testing - Angular 2 RC5 后测试失败

Question

我在测试中使用了以下格式:

export function main() {
    describe('Angular2 component test', function() {
         it('should initialize component',
           async(inject([TestComponentBuilder], (tcb: TestComponentBuilder) => {
              var template = '<specific-component-tag>';
                return tcb.overrideTemplate(TestComponent, template)
                .createAsync(TestComponent)
                .then((fixture) => {
                    expect(fixture.componentInstance.viewChild).toBeDefined();
                    fixture.detectChanges();
                    expect(fixture.componentInstance.viewChild.items.length).toBe(1);
                    // .... etc.
                }).catch (reason => {
                    console.log(reason);
                    return Promise.reject(reason);
                });
         })));
      });
}

这在 RC4 中工作正常。但是RC5突然来了，现在这段代码已经失效了。它抛出以下错误:

Module ".... @angular/core/testing" has no exported member 'it'.
Module ".... @angular/core/testing" has no exported member 'describe'.
Module ".... @angular/core/testing" has no exported member 'expect'.
Module ".... @angular/core/testing" has no exported member 'beforeEachProviders'.
Module ".... @angular/compiler/testing" has no exported member 'TestComponentBuilder'.
Module ".... @angular/compiler/testing" has no exported member 'ComponentFixture'.

请帮助我将此测试迁移到 angular2 RC5。

更新:我已经读过 RC5 release notes但我没有想到如何实现我的目标。

Answer 1

删除了通过@angular/core/testing 提供的 Jasmine 导入。因此，删除以下内容的导入

之前:

import {
  beforeEach,
  beforeEachProviders,
  describe,
  expect,
  it,
  inject,
} from '@angular/core/testing';

之后

/// <reference path="../../../typings/main/ambient/jasmine/index.d.ts" />
import {
  inject, addProviders
} from '@angular/core/testing';

引用路径应该是文件中的第一行，它应该指向 jasmine 类型定义文件。 (更新相对向上。即 ../../到任何)要获得 jasmine 类型定义，请将以下行添加到 ambientDevDependencies。我的看起来像这样

{
  "ambientDevDependencies": {
    "angular-protractor": "registry:dt/angular-protractor#1.5.0+20160425143459",
    "jasmine": "registry:dt/jasmine#2.2.0+20160412134438",
    "selenium-webdriver": "registry:dt/selenium-webdriver#2.44.0+20160317120654"
  },
  "ambientDependencies": {
    "es6-shim": "registry:dt/es6-shim#0.31.2+20160317120654"
  }
}

也改变

  beforeEachProviders(() => [InMemoryDataService]);

到

import { TestBed } from '@angular/core/testing';
...
describe('...', () => {
  TestBed.configureTestingModule({
    providers: [ InMemoryDataService ]
  });
  it(...);
});
