在对AngularJS组件测试进行一些研究时,我读到了关于{strong>视图单元测试的信息,如here所述。我已经尝试过这种方式:
angular.module("recipeDetail").component("recipeSummary", {
templateUrl:
"modules/recipe-detail/recipe-summary/recipe-summary.template.html",
bindings: { recipe: "<" },
controller: function RecipeSummaryController() {}
});
<h1 id="recipe-title">{{ $ctrl.recipe.title }}</h1>
<p>
Steps:
</p>
<ul>
<li ng-repeat="step in $ctrl.recipe.steps" class="recipe-summary-step">
{{ step.text }}
</li>
</ul>
describe("recipeSummary ViewUnitTest", () => {
let scope;
let $compile;
beforeEach(module("recipeDetail"));
beforeEach(inject(($rootScope, _$compile_) => {
scope = $rootScope.$new();
$compile = _$compile_;
}));
it("should display the steps", () => {
scope.recipe = recipe;
let el = angular.element('<recipe-summary recipe="recipe"/>');
el = $compile(el)(scope);
scope.$digest();
expect(el[0].querySelectorAll("p").length).toBe(1); // to make sure this whole thing is working
expect(el[0].querySelectorAll(".recipe-summary-step").length).toBe(3);
});
});
两个断言都失败-第一个(p
)检查我是否正确实施了测试,第二个(.recipe-summary-step
)检查组件的实际功能。
我不觉得自己很蠢。乔治指出,我实际上没有打电话 scope.$digest()
。
所以这样做之后,我遇到了新的错误/失败:
Chrome 74.0.3729 (Mac OS X 10.14.4) recipeSummary ViewUnitTest should display the steps FAILED
Error: Unexpected request: GET modules/recipe-detail/recipe-summary/recipe-summary.template.html

显然,templateUrl
是通过实际的get
请求解决的,显然这是一个致命错误。那么我该如何使用这种技术呢?
