Jmeter压力测试
Jmeter压力测试
1. Jmeter 简介
http://www.cnblogs.com/bravemi/p/5555566.html
一个非常优秀的开源的性能测试工具。
优点：你用着用着就会发现它的重多优点，当然不足点也会呈现出来。
从性能工具的原理划分：
Jmeter工具和其他性能工具在原理上完全一致，工具包含4个部分：
(1)负载发生器：用于产生负载，通常以多线程或是多进程的方式模拟用户行为。
(2)用户运行器：通常是一个脚本运行引擎，用户运行器附加在线程或进程上，根据脚本要求模拟指定的用户行为。
(3)资源生成器：用于生成测试过程中服务器、负载机的资源数据。
(4)报表生成器：根据测试中霍地的数据生成报表，提供可视化的数据显示方式。
2. 安装jmeter
jmeter 是Java程序，在Linux windows Mac系统都可以安装，配置好JDK环境就好
https://jmeter.apache.org/download_jmeter.cgi
双击启动
支持中文，不需要汉化。选项中直接选择中文简体。
3. 测试步骤
1. 写脚本 或者录制脚本
2. 使用用户自定义参数
3. 场景设计
4. 使用控制器，来控制 模拟多少用户。
5. 使用监听器， 查看测试结果

3.4. 参数和结果说明
https://blog.csdn.net/sunwangdian/article/details/50738870
Number of Threads(users): 一个用户占一个线程， 200个线程就是模拟200个用户
Ramp-Up Period(in seconds): 设置线程需要多长时间全部启动。如果线程数为200 ，准备时长为10 ，那么需要1秒钟启动20个线程。也就是每秒钟启动20个线程。
Loop Count: 每个线程发送请求的次数。如果线程数为200 ，循环次数为10 ，那么每个线程发送10次请求。总请求数为200*10=2000 。如果勾选了“永远”，那么所有线程会一直发送请求，直到选择停止运行脚本。
Ramp-up Period（in seconds）
【1】决定多长时间启动所有线程。如果使用10个线程，ramp-up period是100秒，那么JMeter用100秒使所有10个线程启动并运行。每个线程会在上一个线程启动后10秒（100/10）启动。Ramp-up需要要充足长以避免在启动测试时有一个太大的工作负载，并且要充足小以至于最后一个线程在第一个完成前启动。 一般设置ramp-up=线程数启动，并上下调整到所需的。
【2】用于告知JMeter 要在多长时间内建立全部的线程。默认值是0。如果未指定ramp-up period ，也就是说ramp-up period 为零， JMeter 将立即建立所有线程。假设ramp-up period 设置成T 秒， 全部线程数设置成N个， JMeter 将每隔T/N秒建立一个线程。
【3】Ramp-Up Period(in-seconds)代表隔多长时间执行，0代表同时并发

Samples：表示你这次测试中一共发出了多少个请求，如果模拟10个用户，每个用户迭代10次，那么这里显示100
Average：平均响应时间——默认情况下是单个 Request 的平均响应时间，当使用了 Transaction Controller 时，也可以以Transaction 为单位显示平均响应时间
Median：中位数，也就是 50％ 用户的响应时间
90% Line：90％ 用户的响应时间
Note：关于 50％ 和 90％ 并发用户数的含义，请参考下文
http://www.cnblogs.com/jackei/archive/2006/11/11/557972.html
Min：最小响应时间
Max：最大响应时间
Error%：本次测试中出现错误的请求的数量/请求的总数
Throughput：吞吐量——默认情况下表示每秒完成的请求数（Request per Second），当使用了 Transaction Controller 时，也可以表示类似 LoadRunner 的 Transaction per Second 数
KB/Sec：每秒从服务器端接收到的数据量，相当于LoadRunner中的Throughput/Sec

5. 参数接口测试
我所测试的就是带参数的接口，只不过拼接到URL中了
下面这个是更好
