Question

嗨，我有这个简单的测试：

define(["angular", "angularMocks", "app", "normalizer"], function(angular, mocks, app) {

  describe("service: normalizer", function () {
    var normalizerService;

    beforeEach(module("ADB"));

    beforeEach(inject(function(_normalizer_) {
      normalizerService = _normalizer_;
    }));

    var params = {};
    var metadata = {};
    var data = {};

    var response = normalizerService.topLanguagesHybrid(metadata, data, params);

    var type = typeof response;
    expect(type).toEqual("object");

  });
});

问题是从未设置normalizer服务，在cmd中我看到以下错误：

 TypeError: 'undefined' is not an object (evaluating 'normalizerService.topLanguagesHybrid')

注意：我在这个项目中使用requirejs，我可以看到normalizer服务文件正在加载到浏览器中（包含所有依赖项）。似乎它没有注入。我做错了什么？

定义服务时，您忘记定义规范化程序，因此正确的语法是

define(["angular", "angularMocks", "app", "normalizer"], function(angular, mocks, app, normalizerService) {

  describe("service: normalizer", function () {
    var normalizerService;

    beforeEach(module("ADB"));

    var params = {};
    var metadata = {};
    var data = {};

    var response = normalizerService.topLanguagesHybrid(metadata, data, params);

    var type = typeof response;
    expect(type).toEqual("object");

  });
});

对于测试场景，你忘了为它定义它，之后每个运行之前运行它＆＃34;它＆＃34;功能

define(["angular", "angularMocks", "app", "normalizer"], function(angular, mocks, app) {

  describe("service: normalizer", function () {
    var normalizerService;

    beforeEach(module("ADB"));

    beforeEach(inject(function(_normalizer_) {
      normalizerService = _normalizer_;
    }));

    it('should define topLanguageHybrid method', function() {
      var params = {};
      var metadata = {};
      var data = {};

      var response = normalizerService.topLanguagesHybrid(metadata, data, params);

      var type = typeof response;
      expect(type).toEqual("object");
    });
  });
});
