Question

我想为我的test/src/rating/rating.html/dart组件（<rating>）编写单元测试（lib/rating/rating.dart/html）。

void main() {
  useHtmlEnhancedConfiguration();

  ng.Scope _rootScope;
  dom.Element _element;
  ngMock.TestBed _tb;

  setUp(() {
    try {
    ngMock.setUpInjector();

      ngMock.module((ng.Module module) {
        module.install(new RatingModule());
      });

      ngMock.inject((ng.Scope scope, ngMock.TestBed testBed) {
        _rootScope = scope;
        _rootScope['rate'] = 3;
        _tb = testBed;
        _element = _tb.compile('<rating value="rate"></rating>', scope: _rootScope);
        _rootScope.$digest();

      });
      print('setUp done');
    } catch(e) {
      print(e);
    }
  });

第_element = _tb.compile('<rating value="rate>...行失败

[意外请求：GET packages / bootstrap_angular / rating / rating.html

我将组件templateUrl更改为模板，并将模板HTML指定为字符串并删除了异常。

我做错了还是不支持？

我创建了issue in the Angular.dart GitHub repository。随着我得到的回应，我认为这有效，但是相当冗长：

void main() {
  useHtmlEnhancedConfiguration();

  ng.Scope _rootScope;
  dom.Element _element;
  ngMock.TestBed _tb; 
  ngMock.MockHttpBackend _backend; // new

  setUp(() {
    Future f;
    try {
    ngMock.setUpInjector();

      ngMock.module((ng.Module module) {
        module.install(new RatingModule());
      });

      ngMock.inject((ng.Scope scope, ngMock.TestBed testBed) {
        _rootScope = scope;
        _rootScope['rate'] = 3;
        _tb = testBed;

        f = dom.HttpRequest.getString('/bootstrap_angular/packages/bootstrap_angular/rating/rating.html') // new
        .then((ratingTemplate) { // new
          _backend = new ngMock.MockHttpBackend(); // new
          print(ratingTemplate); // just debug output
          _backend.expect('GET').respond(ratingTemplate); // new

          _element = _tb.compile('<rating value="rate"></rating>', scope: _rootScope);
          var element =_element.shadowRoot.querySelector('i');
          _rootScope.$digest();
        });
      });
    } catch(e) {
      print(e);
    }
    return f; // new 
    // return a future to make the tests wait until setUp is done
