| 初次体验openSTA

0Jz@/e6FS(Z0最近研究一个开源的性能测试功能openSTA，网上资源确实太少，刚巧最近工作留给我的时间很少。

#N*??dzMn9Vl`0将下面代码复制到 scrīpt Modeler 中，在Commander里运行，查看其Test Report Log。51Testing软件测试网2VD:mn%E/quA&VIP

此脚本虽小，且简单，但你确可从中明白openSTA的一些实现过程。

一、从UserID你可以知道，并发的三个用户，开始运行是没有先后顺序的。

二、从Line#你可以知道，代码7行处的m一直等于0，代码11行、13行都是从1递增。51Testing软件测试网o$gS$^2P^!Y!B

三、给我留下了一个疑点，ACQUIRE MUTEX 、RELEASE MUTEX 的作用和区别。51Testing软件测试网*d_9xl+B-on%y

Help文档描述如下：51Testing软件测试网 ]*s y.B'C
ACQUIRE MUTEX Command51Testing软件测试网L*ZpCyj;ws+sxG@
This command acquires exclusive access to a shared resource, known as a mutex. The mutex is identified by its name and scope (which must be either LOCAL or TEST-WIDE). A test-wide mutex is one that is shared by all scrīpts running as part of a distributed test; a local mutex is only shared between scrīpts running on the local node.

P)u*rd!\fL0This command releases a named mutex. The mutex to be released is identified by its name and scope, which must correspond to the values specified on the corresponding ACQUIRE MUTEX command.
