如何編寫測試用例以執行刪除操作

Question

考慮到以下代碼是「保存」測試用例 - 我將如何編寫「刪除」測試用例？

[Test] 
     public void Testsavesassignment() 
     { 
      var sAssignment = new SAssignment() 
      { 
       DateCreated = DateTime.Now, 
       DateUpdated = DateTime.Now, 
       Department = 9000.ToString(), 
       EmployeeId = 4342342 

      }; 
      Status status = null; 
      var assignment = this.m_personnelService.SaveSAssignment(sAssignment, out status); 
      Assert.IsTrue(status.Success); 
      Assert.AreEqual(sAssignment.EmployeeId, assignment.EmployeeId); 
      Assert.AreEqual(sAssignment.EmployeeId, assignment.DateCreated); 
      Assert.AreEqual(sAssignment.DateUpdated, assignment.DateUpdated); 
      Assert.AreEqual(sAssignment.Department, assignment.Department); 
      Assert.AreNotEqual(sAssignment.Id, assignment.Id); 

     } 

Answer 1

你將不得不瞭解一下的m_personnelService底層實現，如果你希望能夠測試出刪除。

下面介紹如何使用實體框架實現單元測試（包括刪除）：http://msdn.microsoft.com/en-us/library/ff714955.aspx（跳轉到標題爲「以EF爲中心的實現」的部分 - 除此之外，測試還有幾個部分） 。

這可能有助於...

[Test] 
    public void TestDeleteAssignment() 
    { 
     //add assignment 
     var myAssignment = new SAssignment() 
     { 
      DateCreated = DateTime.Now, 
      DateUpdated = DateTime.Now, 
      Department = 9000.ToString(), 
      EmployeeId = 4342342 
     }; 

     Status addStatus = null; 
     var assignment = this.m_personnelService.SaveSAssignment(myAssignment, out addStatus); 
     Assert.IsTrue(addStatus.Success); 

     var targetAssignmentId = assignment.Id; 

     //possibility 1 
     Status deleteStatus = null; 
     var assignment2 = this.m_personnelService.DeleteSAssignment(targetAssignmentId, out deleteStatus); 
     Assert.IsTrue(deleteStatus.Success); //or Assert.AreEqual(assignment2.Id, targetAssignmentId); 


     //possibility 2 
     Status deleteStatus = null; 
     var assignment3 = this.m_personnelService.DeleteSAssignment(targetAssignmentId); 
     var result = this.m_personnelService.GetSAssignment(targetAssignmentId); 
     Assert.IsNull(result); 
    }
