angularjs karma jasmine undefinedはオブジェクトではありません

Question

私のangularjsプロジェクトで単体テストを使い始めようとしています。しかし、このエラーを取得し、問題の原因を把握できませんでした。

fibonacci.service.js

(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; 
 
    }; 
 
    
 
    } 
 
})();

fibonacci.service.tests.js

'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); 
 
    }); 
 

 
});

誰かを助けてください。

Answer 1

次のように私は正常に実行ユニットテストを許可するようにコードを修正：

• をサービス

(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; 
    }; 
    } 
})(); 

• ユニットテスト

'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

私は考え出しこれはアウト。私はGruntfile.js内のすべてのバウアー依存関係を読み込まなければなりませんでした。
