如何使用Jasmine和AngularJS编写测试？

Question

我正在为Post调用编写单元测试，我在测试套件中有假数据，我发布到端点，但它给了我一个我附加到这个问题的错误。我是新来的茉莉花任何想法实施这个测试案例更好的方式将不胜感激。

到目前为止已经试过代码..

main.spec.js

describe('processFactory', function(){ 
    'use strict'; 

    var $httpBackend,Process; 
    beforeEach(module('riskAssessmentApp')); 

    beforeEach(inject(function(_$httpBackend_ , processFactory) { 
     $httpBackend = _$httpBackend_; 
     Process = processFactory; 

    })); 
    // make sure no expectations were missed in your tests. 
    afterEach(function() { 
     // $httpBackend.verifyNoOutstandingExpectation(); 
     $httpBackend.verifyNoOutstandingRequest(); 
    }); 

    it('should be able to save process to the database',function(){ 
    var epcfData = [{"type":"Epcf","id":2102}]; 
    var erhData = [{"type":"Erh", "id":20001}]; 
    var geoData =[{"type":"geoLocation", "id": 67000}]; 
    var legalData = [{"type":"legal", "id":3358}]; 
    var prcsObj = { 
     processLongName: "Process unit test 01", 
     processStatementText: "Process statement test 01", 
     epcfUtilKeyList: epcfData, 
     epcfDescription: "Epcf selected key description test 01", 
     businessSegmentOrControlFunction: "business segment test 01", 
     erhUtilKeyList: erhData, 
     geoLocationsKeyList: geoData, 
     legalEntitiesKeyList: legalData, 
     processOwnerWorkerKey: -1069, 
     prcsOwner: "xyz" 
    }; 

     var promise = Process.saveProcess(); 
     httpBackend = expectPOST('app/prcs/rest/process',prcsObj).respond(200,'success'); 

     httpBackend.flush(); 
     promise.then(function(res){ 
     expect(res.data).toBe('success'); 
     }); 

    }); 

}); 

mainFactory.js

var serializeProcess = function (process) { 
      var objToReturn = { 
       processLongName: process.processLongName, 
       processStatementText: process.processStatementText, 
       epcfKey: process.epcfUtilKeyList[0].id, 
       epcfDescription: process.epcfDescription, 
       businessSegmentOrControlFunction: process.businessSegmentOrControlFunction, 
       erhKey: process.erhUtilKeyList[0].id, 
       geographicLocationKeyList: [], 
       legalEntityKeyList: [], 
       processOwnerWorkerKey: process.processOwnerWorkerKey, 
       prcsOwner: process.prcsOwner 

      }; 

saveProcess: function(process, id){ 
       var request = serializeProcess(process); 
       console.log('request payload', JSON.stringify(request)); 
       console.log('ID :: ', id); 
       // do this if you have differnet end point for save and update 
       //var endpoint = (id) ? 'app/prcs/rest/process/' + id : 'app/prcs/rest/process'; 
       var endpoint = 'app/prcs/rest/process'; 
       return $http.post(endpoint, request); 
      } 

错误

现在我得到不同的错误，请参阅更新的错误找不到变量：expectPost

Answer 1

你看上去不及格prcsObj或id到saveProcess()方法在测试和你没有建立你的对象的方式，方法的期望。例如，您在prcsObj中缺少epcfUtilKeyList阵列。

应该是这个样子：

it('should be able to save process to the database',function(){ 
    var epcfData = [{"type":"Epcf","id":2102}] 
    var prcsObj = { 
     processLongName: "Process unit test 01", 
     processStatementText: "Process statement test 01", 
     epcfUtilKeyList: epcfData, 
     epcfDescription: "Epcf selected key description test 01", 
     businessSegmentOrControlFunction: "business segment test 01", 
     erhUtilKeyList: [{ "id": 20001}], 
     processOwnerWorkerKey: 1254, 
     prcsOwner: "xyz" 
    }; 

    var promise = Process.saveProcess(prcsObj); 
    $httpBackend.expectPOST('app/prcs/rest/process',prcsObj).respond(200,'success'); 

    $httpBackend.flush(); 
    promise.then(function(res){ 
    expect(res.data).toBe('success'); 
    }); 

}); 

您仍有可能丢失的信息，但基于您发布这应该工作的方法。
