问题描述

如果我的测试计划中有3个线程组，如何为每个组设置恒定的概率(请求权重)? 我是JMeter的新手.您能在屏幕截图上显示您的设置吗?

If I have 3 thread groups in my test plan, how can I set the constant probability (request weights) for each group? I'm a novice in JMeter. Could you, please, show your settings on the screenshots?

推荐答案

只需将每个组的线程数设置为测试总线程数的一个因数. 如果是100个VU，则将g1设置为50，将g2设置为30，将g3设置为20.

Well just set the number of threads of each group to a factor of the total threads of your test. If 100 VUs, set 50 for g1, 30 for g2 and 20 for g3.

要使其动态，可以使用 BeanShell 函数，您可以设置Number的线程数:

To make it dynamic you can use BeanShell function, you would set Number of Threads to:

${__BeanShell(50*${USERS}/100)}

并且将使用用户定义的变量，该变量包含:

And would use a User Defined Variables containing:

USERS : ${__P(USERS, 10)} // for 10 users by default,

然后可以将用户作为命令行选项传递:

USERS can then be passed as a Command line options:

-JUSERS=100
