如何平均增加3个线程组中的用户数量，以节省它们之间的请求比例? [英] How to evenly increase number of users in 3 Thread Groups saving proportion of requests between them?
问题描述
我的测试计划中有3个线程组. 这些线程组必须具有固定的请求权重(例如1st-50％，2nd-40％，3rd-10％). 如果我需要模拟恒定数量的用户，请参阅本文中的解决方案如果将循环计数"设置为数字(1、10、100等)，则@ PMD UBIK-INGENIERIE 的效果很好.但是问题是，当我为循环计数"设置永远"复选框时，组之间的比例被破坏了.
I have 3 Thread Groups in my test plan. These Thread Groups must be with fixed request weights (for example 1st-50%, 2nd-40%, 3rd-10%). If I need to emulate constant number of users, the solution in this post which was given by @PMD UBIK-INGENIERIE works good if I set Loop Count as number (1, 10, 100 ect.). But the problem is when I set the check-box "forever" for Loop Counts, the proportion between groups is broken.
现在，我需要增加用户数量，保存3个组之间的请求比例，以进行容量评估. 这3个小组必须以50-40-10的恒定比例均匀地发送请求.
Now I need to increase the amount of users, saving proportion of requests between my 3 groups, to perform the capasity assessment. All 3 groups must send requests evenly, in this constant proportion 50-40-10.
如果我使用步进线程组，则可以平均增加每个用户的数量，但是无法设置对他们的请求比例.
If I use Stepping Thread Group, I can evenly increase number of users in each of them, but I can't set the proportion of request for them.
您能告诉我任何想法吗，怎么做?
Could you please tell me any idea, how to do this?
UPD1.
我的设置截图:
和
怎么了?
UPD2.最后一个变量(我为每个组手动设置了数字)是(线程组1-50％):
UPD2. The last variant (I have put numbers manually for each group) is (Thread Group1 - 50%):
推荐答案
-
在用户定义的变量"或测试计划变量"中设置USERS变量(或可以通过命令行传递它).
还设置变量:
Set USERS variable in User Defined Variables or test plan variables (or you can pass it through command line).
Also set variables:
PERCENT1 to 0.5
PERCENT2 to 0.4
PERCENT3 to 0.1
添加3个步进线程组:
Add 3 stepping thread groups with:
该组将开始"设置为
${__BeanShell(Math.round(${PERCENT1}*${USERS})}
${__BeanShell(Math.round(${PERCENT2}*${USERS})}
${__BeanShell(Math.round(${PERCENT3}*${USERS})}
然后开始"设置为:
${__BeanShell(Math.round(${PERCENT1}*${USERS}/10)}
${__BeanShell(Math.round(${PERCENT2}*${USERS}/10)}
${__BeanShell(Math.round(${PERCENT3}*${USERS}/10)}
如果USERS变量的值可以除以100，它将起作用
It will work if value of USERS variable can be divided by 100
