軟件單元測試的測試用例編寫(xiě)方法

 軟件單元測試的測試用例編寫(xiě)方法

MILY: 宋體; mso-ascii-font-family: " Times Roman?; mso-hansi-font-family: ?Times New Roman??>我在這里用最常用的方法：基本路徑測試法來(lái)進(jìn)行單元測試，因為我要用一個(gè)實(shí)際的例子來(lái)進(jìn)行說(shuō)明，所以就編寫(xiě)了下面一個(gè)程序模塊，就暫且命名為“詳細查詢(xún)模塊”吧。

void CXIANGXIDLG::OnOK()
{
CoInitialize(NULL);//初始化COM環(huán)境
_ConnectionPtr m_pConnection;//連接對象
  HRESULT hr;    

  try
  {

if(SUCCEEDED(hr))    
    {
hr=m_pConnection->Open("Provider=Microsoft.Jet.OLEDB.4.0;DataSource=shouji.mdb","","",adModeUnknown);//連庫
    }
  }
  catch(_com_error e)
  {
AfxMessageBox("數據庫連接失敗，確認數據庫連接字符串是否正確");
  }
  //操縱表

  CString strSQL;

  {

  int lenth=0;
  lenth=m_name.GetLength();
