我尝试测试一些组件： https://gist.github.com/Rasarts/000e233092b6781128a8488cbbb7a051
dependencies:
angular2: '^3.0.0-alpha+1'
angular2_components: '^0.4.0-alpha'
dev_dependencies:
angular_test:
git: "https://github.com/dart-lang/angular_test.git"
version: '^1.0.0-alpha+5'
test: '^0.12.20+2'
@Component(selector: 'page-view', templateUrl: 'page_view_component.html')
class PageViewComponent {}
@AngularEntrypoint()
void main() {
test('Should create a new component in the DOM', () async {
NgTestBed testBed = new NgTestBed<PageViewComponent>();
NgTestFixture fixture = await testBed.create();
expect(fixture.rootElement.innerHtml, contains("PageViewComponent"));
});
}
当我运行 pub run test -p dartium 命令时，我的测试失败了：

如何进行测试？
答案 0 :(得分：3)
尝试返回angular2版本3.0.0-alpha。 angular_test仍在进行中，需要更新才能使用3.0.0-alpha + 1。
