背景
为了更好了解nGrinder怎么工作或者为下次二次开发便开启使用源码部署。
下载源码:
https://github.com/naver/ngrinder/releases
也可以直接通过:https://github.com/naver/ngrinder.git这种方式下部署
本次使用下载zip进行安装:
点击目录再点击:
等待执行成功便把如下安装到本地创库:
打开idea:
点击文件导入:
点击Open as Project:
打开新窗口:
等待maven加载相应的jar。
修改代码
具体代码如下:
package org.ngrinder.perftest.service;
import org.ngrinder.infra.config.Config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.EnableAspectJAutoProxy;
import org.springframework.context.annotation.Profile;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.transaction.annotation.EnableTransactionManagement;
/**
* Dynamic creation of {@link PerfTestService} depending on the cluster enable or disable.
*
* @author JunHo Yoon
* @since 3.1
*/
@Configuration
@Profile("production")
@EnableScheduling
@EnableTransactionManagement
@EnableAspectJAutoProxy
public class PerfTestServiceConfig implements ApplicationContextAware {
@Autowired
private Config config;
private ApplicationContext applicationContext;
/**
* Create PerTest service depending on cluster mode.
*
* @return {@link PerfTestService}
*/
@Bean(name = "perfTestService")
public PerfTestService perfTestService() {
if (config.isClustered()) {
return applicationContext.getAutowireCapableBeanFactory().createBean(ClusteredPerfTestService.class);
} else {
return applicationContext.getAutowireCapableBeanFactory().createBean(PerfTestService.class);
}
// return applicationContext.getAutowireCapableBeanFactory().createBean(
// config.isClustered() ? ClusteredPerfTestService.class : PerfTestService.class);
}
@Override
public void setApplicationContext(ApplicationContext applicationContext) {
this.applicationContext = applicationContext;
}
}
再次配置tomcat
选择tomcat所在目录:
选择:
添加运行war:
选择时时更新运行:
注意最好是这样:
-Xms1024m -Xmx1024m -XX:MaxPermSize=200m防止内存出现异常显现
点击确定:
启动:
打开浏览器验证是否成功:
http://localhost:8081/ngrinder/login
登录成功:
使用源码调试简单脚本
在script-sample工程下的pom.xml文件种增加:
代码如下
<!-- https://mvnrepository.com/artifact/junit/junit -->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
再次在idea中全局搜索:
groovy-all
查看版本号,统一修改为:
<version>2.4.16</version>
模仿编写脚本
通过平台生成脚本:
点击:
查看脚本
importstatic net.grinder.script.Grinder.grinder
importstatic org.junit.Assert.*
importstatic org.hamcrest.Matchers.*
import net.grinder.plugin.http.HTTPRequest
import net.grinder.plugin.http.HTTPPluginControl
import net.grinder.script.GTest
import net.grinder.script.Grinder
import net.grinder.scriptengine.groovy.junit.GrinderRunner
import net.grinder.scriptengine.groovy.junit.annotation.BeforeProcess
import net.grinder.scriptengine.groovy.junit.annotation.BeforeThread
// import static net.grinder.util.GrinderUtils.* // You can use this if you're using nGrinder after 3.2.3
import org.junit.Before
import org.junit.BeforeClass
import org.junit.Test
import org.junit.runner.RunWith
import java.util.Date
import java.util.List
import java.util.ArrayList
importHTTPClient.Cookie
importHTTPClient.CookieModule
importHTTPClient.HTTPResponse
importHTTPClient.NVPair
/**
* A simple example using the HTTP plugin that shows the retrieval of a
* single page via HTTP.
*
* This script is automatically generated by ngrinder.
*
* @author admin
*/
@RunWith(GrinderRunner)
classTestRunner{
publicstaticGTest test
publicstaticHTTPRequest request
publicstaticNVPair[] headers = []
publicstaticNVPair[] params= []
publicstaticCookie[] cookies = []
@BeforeProcess
publicstaticvoid beforeProcess() {
HTTPPluginControl.getConnectionDefaults().timeout = 6000
test = newGTest(1, "www.baidu.com")
request = newHTTPRequest()
grinder.logger.info("before process.");
}
@BeforeThread
publicvoid beforeThread() {
test.record(this, "test")
grinder.statistics.delayReports=true;
grinder.logger.info("before thread.");
}
@Before
publicvoid before() {
request.setHeaders(headers)
cookies.each { CookieModule.addCookie(it, HTTPPluginControl.getThreadHTTPClientContext()) }
grinder.logger.info("before thread. init headers and cookies");
}
@Test
publicvoid test(){
HTTPResponse result = request.GET("https://www.baidu.com/", 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));
}
}
}
复制脚本:
在idea中新建脚本脚本
选择groovy脚本
输入名字点击保存即可
新建完毕把刚才脚本复制过来修改下方法名称
如下:
点击运行:
提示:
解决方法:
在Idea菜单栏->Run->Edit Configurations->Default->Junit->在VM options填写自定义配置,点击Apply按钮保存配置即生效
再次点击:
运行结果如下:
本机脚本调试成功:
下次再次分享本地参数化与post请求
送大家一句话:
学习不等于学会!知道不等于做到!唯有严格的反复操练!才是灵活应用的保证!学习向学会走近一步,知道向做到拉近了一些,反复的练习向应用靠近了距离,我们只要走,就会见到别人的微笑。
