數據池在javascript:;" onClick="javascript:tagshow(event, 'rational');" target="_self">rational測試中是使用率很高，同時它也充分體現了自動化測試的優勢。通過使用數據池，可以通過簡單的腳本完成大量數據的測試，縮短測試時間、提高測試效率和測試質量。下面將介紹數據池的概念、創建以及在GUI、VU腳本中的應用。
    數據池（DATAPOOL）用于存儲測試數據，在腳本中插入數據池命令并增加相關的控制命令后，在腳本回放時就可以自動從數據池中取出數據，完成多組測試數據的測試。
（一）數據池（DATAPOOL）創建
1、啟動Rational TestManager；
2、Tools>Manage>Datapool，點擊New…，輸入數據池名稱點“確定”；
3、在打開的Data Type Specification中添加字段定義；
字段定義說明：
Name：字段名稱
Type：數據類型
Sequence：次序，包括Random（隨機）、Sequential（連續）、Unique（唯一）
Repeat：數據重復次數
Length：數據長度
Decimals：小數位數
Interval：間隔，相鄰兩個數據的間隔數
Mininum：最小值
Maxinum：最大值
Seed：Sequence設為Random時，Seed輸入不同的數據，生成不同的隨機數
4、在設置好字段后，在No. of records to genarete：中輸入要生成的記錄數，然后點擊Genarete Data 即可生成數據，或者點擊SAVE按鈕，關閉當前窗口，然后點擊manage datapools>edit>edit datapool data，直接手工輸入數據；
5、這樣就完成了數據池的創建，還可以執行數據池的編輯、改名、刪除、導入、導出等操作；
6、數據池有數據生成能力，但是不具備數據的計算能力。這種情況下可以利用其他工具（如EXCEL）生成數據，并保存為csv(逗號分割文件)格式，然后在manage datapools中導入；
（二）、
1、數據池在GUI腳本中的應用
這是計算器測試的例子，在GUI中使用數據池需要手工編碼，robot');" target="_self">robot不能自動生成，在手工編碼時可以參考Robot的在線幫助。
'$Include "sqautil.sbh"

Sub Main
    Dim Result As Integer
    dim x as integer
    dim num1 as string
    dim num2 as string
    dim sum as string

   
    'Initially Recorded: 2003-7-18  8:51:18
    'Script Name: 計算器－2

    StartApplication "C:\WINNT\system32\calc.exe"
   
    dp=SQADatapoolOpen("jsq"
'打開數據池，jsp為數據池的名稱，這個數據池是預先按照上述規范做好的

    for x=1 to 5
Call SQADatapoolFetch(dp)
'從數據池中讀取記錄
    Call SQADatapoolValue(dp,1,num1)
    Call SQADatapoolValue(dp,2,num2)
Call SQADatapoolValue(dp,3,sum)
'將從數據池中讀取的數據賦予相應變量
    Window SetContext, "Caption=計算器", ""
    InputKeys num1 &"{+}"& num2 &"{ENTER}"
   
    Result = LabelVP (CompareNumeric, "Text="& sum &".", "VP=Alphanumeric;Value="& sum &"."
   
    next
   
    Call SQADatapoolClose(dp)
    '關閉數據池
    Window CloseWin, "", ""

End Sub

2、數據池在VU腳本中的應用
   VU腳本中的數據池可以通過錄制自動產生，如果不能自動產生可以手工編碼加入。

   以下錄制在Google上搜索的腳本，數據池時錄制時自動產生的：
  #include <VU.h>

push Timeout_scale = 200; /* Set timeouts to 200% of maximum response time */
push Think_def = "LR";
Min_tmout = 120000;       /* Set minimum Timeout_val to 2 minutes          */
push Timeout_val = Min_tmout;

DP1 = datapool_open("googlw";
datapool_fetch(DP1);
            
push Think_avg = 0;

www_google_com = http_request ["googlw001"] "www.google.com:80",

以下是全部手工編寫的使用數據池的VU腳本：
#include <VU.h>
{
push Timeout_scale = 200; /* Set timeouts to 200% of maximum response time */
push Think_def = "LR";
Min_tmout = 120000;       /* Set minimum Timeout_val to 2 minutes          */
push Timeout_val = Min_tmout;
DP1 = datapool_open("test");   //打開數據池

ser=sqlconnect("server","sa","8888","192.168.1.12","sqlserver");
set Server_connection = ser;
push Think_avg = 0;

for (i=0; i<10; i++)
{
   datapool_fetch(DP1); //移動指針到下一記錄
   sqlexec ["sql_1000"] "TestDB..test " +datapool_value(DP1, "q");
}
sqldisconnect (ser);
datapool_close (DP1);   //關閉數據池
}

DATAPOOL_CONFIG "test"  DP_SEQUENTIAL DP_SHARED DP_WRAP
{
        INCLUDE, "q", "string", "8";
}

    GUI中的數據池只能手工編碼修改，VU中的數據池可以通過edit――datapool infoermation進行配置。此菜單在GUI腳本下為灰色不可操作。
