性能测试四十九：ngrinder压测平台

直接上ngrinder官网下载

ngrinder工作原理：这里的controller就是ngrinder平台

部署（以windows为例）：

把下载下来的ngrinder-controller.war重命名为ngrinder.war放到tomcat下面，启动tomcat

启动完浏览器访问：http://localhost:8080/ngrinder

默认用户名admin，密码admin，选择中文

登录成功后下载agent和monitor

解压并启动agent

在机器足够的情况下，应该把agent单独部到一台机器上，由于机器有限这里和ngrinder部到同一台机器

先编辑配置文件：__agent.conf，修改ngrinder所在的ip和端口号（默认端口号16001）

双击启动文件，下面这样就算启动成功了

把前面下载的monitor上传至服务器，并解压

进入到该目录，里面的东西和agent一样

启动，这里第一次报错，说没有找到本机路由，后来查看，是因为当前host里面没有配置当前使用的这个ip

改host文件

再次启动，成功

回到ngrinder，编写脚本

这里对java和python哪个熟一点就选哪个

先确认接口是通的：

Groovy（java版）：

点创建后会生成如下代码：

import static net.grinder.script.Grinder.grinder
import static org.junit.Assert.*

public static GTest test

cookieList.add(new Cookie("uid", "abc", "192.168.1.163", "/", new Date(32503647599000L), false))

grinder.logger.info("before process.");
}

@BeforeThread
public void beforeThread() {
test.record(this, "test")

grinder.logger.info("before thread.");
}

public void before() {
request.setHeaders(headers)
cookies.each { CookieModule.addCookie(it, HTTPPluginControl.getThreadHTTPClientContext()) }
grinder.logger.info("before thread. init headers and cookies");
}

@Test
public void test(){
HTTPResponse result = request.GET("http://192.168.1.163:8080/PerfTeach/TimeMonitor?id=1", params)

if (result.statusCode == 301 || result.statusCode == 302) {
grinder.logger.warn("Warning. The response may not be correct. The response code was {}.", result.statusCode);
} else {
assertThat(result.statusCode, is(200));
}
}
}

点验证脚本，在控制台最下面有日志，可以看到通不通过
