Angular 2测试吞咽承诺

Question

测试角度2组件，但似乎吞下了一个承诺。我已经设置了一个内部期望，它应该总是失败（期望false为真）但它不会抛出异常并导致测试通过。有什么想法吗？

使用ng2 rc1

测试

import { it, ddescribe, expect, inject, async, beforeEachProviders } from '@angular/core/testing';
import { provide } from '@angular/core';
import {
  TestComponentBuilder,
  ComponentFixture
} from '@angular/compiler/testing';
import { Http, BaseRequestOptions } from '@angular/http';
import { LoginComponent } from './..';
import { MockBackend } from '@angular/http/testing';
import { UserService } from '../../';

ddescribe('LoginThing', () => {
  it('should wrap content', async(inject([TestComponentBuilder], (tcb: TestComponentBuilder) => {
    console.log('Ready to run test');
    return tcb.createAsync(LoginComponent)
        .then((fixture: ComponentFixture<LoginComponent>) => {
          console.log(fixture);
          fixture.detectChanges();
          var compiled = fixture.debugElement.nativeElement;
          expect(compiled).toContainText('stuff');
          expect(false).toBe(true);
        });
  })));
});

业力测试垫片

/*global jasmine, __karma__, window*/
Error.stackTraceLimit = Infinity;
jasmine.DEFAULT_TIMEOUT_INTERVAL = 1000;

__karma__.loaded = function () {
};

var distPath = '/base/.test/';
var appPath = distPath + 'app/';

function isJsFile(path) {
  return path.slice(-3) == '.js';
}

function isSpecFile(path) {
  return path.slice(-8) == '.spec.js';
}

function isAppFile(path) {
  return isJsFile(path) && (path.substr(0, appPath.length) == appPath);
}

var allSpecFiles = Object.keys(window.__karma__.files)
  .filter(isSpecFile)
  .filter(isAppFile);

// Load our SystemJS configuration.
System.config({
  baseURL: distPath,
});


System.import('system.config.js').then(function(e) {
  // Load and configure the TestComponentBuilder.
  return Promise.all([
    System.import('@angular/core/testing'),
    System.import('@angular/platform-browser-dynamic/testing')
  ]).then(function (providers) {
    var testing = providers[0];
    var testingBrowser = providers[1];
    testing.setBaseTestProviders(
      testingBrowser.TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
      testingBrowser.TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS
    );
  });
}).then(function() {
  return Promise.all(
    allSpecFiles.map(function (moduleName) {
      return System.import(moduleName);
    }));
}).then(__karma__.start, __karma__.error);
