Question

我试图在angularjs项目中开始使用单元测试。但是得到这个错误并且无法找出问题原因。

fibonacci.service.js

＆＃13;

dictvectorizer

＆＃13;

fibonacci.service.tests.js

＆＃13;

(function () {
  'use strict';

  angular.module('myFirstApp').service('FibonacciService', FibonacciService);

  //FibonacciService.$inject = [];
  function FibonacciService() {

    // iterative approach
    this.fibonacci = function (num) {
      var prev1 = 1,
        prev2 = 0,
        current = 0;
      for (var n = 2; n <= num; n++) {
        current = prev1 + prev2;
        prev2 = prev1;
        prev1 = current;
      }
      return current;
    };
    
  }
})();

＆＃13;

Gruntfile.js

＆＃13;

'use strict';
describe('myFirstApp.FibonacciService', function() {

  var FibonacciService;

  beforeEach(module('myFirstApp'));
  beforeEach(module('app.admin'));
  beforeEach(inject(function($injector) {
    FibonacciService = $injector.get('FibonacciService');
  }));

  it('Should output correct Fibanacci numbers', function() {
    expect(FibonacciService.fibonacci(0)).toBe(0);
    expect(FibonacciService.fibonacci(1)).toBe(1);
    expect(FibonacciService.fibonacci(10)).toBe(55);
  });

});

Answer 1

我修复了你的代码，以便成功运行单元测试，如下所示：

服务

(function () {
  'use strict';    
  angular.module('myFirstApp', []).service('FibonacciService', FibonacciService);

  function FibonacciService() {

    // iterative approach
    this.fibonacci = function (num) {

      if (num === 0) {
        return 0;
      }

      if (num === 1) {
        return 1;
      }

      var prev1 = 1,
        prev2 = 0,
        current = 0;

      for (var n = 2; n <= num; n++) {
        current = prev1 + prev2;
        prev2 = prev1;
        prev1 = current;
      }

      return current;
    };
  }
})();

单元测试

'use strict';
describe('myFirstApp.FibonacciService', function () {

  var FibonacciService;

  beforeEach(module('myFirstApp'));
  beforeEach(inject(function ($injector) {
    FibonacciService = $injector.get('FibonacciService');
  }));

  it('Should output correct Fibanacci numbers', function () {
    expect(FibonacciService.fibonacci(0)).toBe(0);
    expect(FibonacciService.fibonacci(1)).toBe(1);
    expect(FibonacciService.fibonacci(10)).toBe(55);
  });
});

Answer 2

我想出来了。我不得不在Gruntfile.js

中加载所有bower依赖项

Angularjs karma jasmine undefined不是一个对象
