前段时间在做性能测试的时候，基于业务的需求，使用到了Unique Number的参数类型。
脚本的业务是注册以alien开头，后面接数字的用户帐号，填写相关帐号信息、提交企业信息进行审核。
其中用户帐号是alien开头拼接一个唯一数字的参数，如图：
下面对Unique Number进行相关解释，先引用官方资料：(相信大家也理解这段话的意思)
Unique Number: Assigns a range of numbers to be used for each Vuser. You specify the start value and the block size (the amount of unique numbers to set aside <br>for each Vuser). For example, if you specify a start value of 1 and a block size of 100 the first Vuser can use the numbers 1 to 100, the second Vuser can use<br>the numbers 201-300, etc
先用50个虚拟用户跑场景（不设置持续时间，迭代10次）来验证下这个官方解释。场景跑完后会往数据库中插入注册的数据。这样就可以用PL/SQL来进行验证。PL/SQL块内容如下：
DECLARE RESULT VARCHAR(1024); TYPE MYRECORD IS RECORD( RES T_USER.FUSERID%TYPE); REC_1 MYRECORD; BEGIN SELECT DECODE(MOD(MAX(TO_NUMBER(SUBSTR(FUSERID, 6, LENGTH(FUSERID)),99999999)),100), 0, MAX(TO_NUMBER(SUBSTR(FUSERID, 6, LENGTH(FUSERID)), 99999999)) / 100, ROUND(MAX(TO_NUMBER(SUBSTR(FUSERID, 6, LENGTH(FUSERID)),99999999)) / 100 + 0.5,0)) INTO REC_1.RES FROM T_USER T WHERE FUSERID IN (SELECT A.FUSERID FROM YH_QYJCXX A WHERE A.QYMC LIKE '企业alien%'); FOR I IN 1 .. REC_1.RES LOOP SELECT WMSYS.WM_CONCAT('alien' || SUBSTR(FUSERID, 6, LENGTH(FUSERID))) INTO RESULT FROM T_USER B WHERE B.FUSERID IN (SELECT A.FUSERID FROM YH_QYJCXX A WHERE A.QYMC LIKE '企业alien%') AND SUBSTR(FUSERID, 6, LENGTH(FUSERID)) / 100 <= I AND SUBSTR(FUSERID, 6, LENGTH(FUSERID)) / 100 > I - 1 ORDER BY TO_NUMBER(SUBSTR(FUSERID, 6, LENGTH(FUSERID)),99999999); DBMS_OUTPUT.PUT_LINE('虚拟用户' || I || '产生的数据为:' || RESULT); END LOOP; END; |
