准备CSV数据文件
添加CSV Data Set Config
在请求中使用变量
运行测试
每个用户使用不同数据

实战：登录接口参数化

1. 准备数据文件 (login_data.csv):

csv 复制代码 
username,password,expected_code
admin,Admin@123,200
user01,User01@123,200
user02,User02@123,200
invalid,,401
locked,Locked@123,403

2. 添加 CSV Data Set Config:

复制代码 
右键 Thread Group → Add → Config Element → CSV Data Set Config
配置：
- Filename: login_data.csv
- Variable Names: username,password,expected_code
- Delimiter: ,
- Recycle: true（数据用完后循环）
- Stop Thread: false

3. 在 HTTP Request 中使用变量:

json 复制代码 
{
  "username": "${username}",
  "password": "${password}"
}

4. 添加断言验证:

复制代码 
右键 HTTP Request → Add → Assertion → Response Assertion
- Field to Check: Response Data（响应数据）
- Pattern Match Rules: Contains
- Patterns to Test: "code":${expected_code}

5.3 关联（Correlation）

餐厅比喻 ：关联就像用会员卡点菜------你先办会员卡（登录获取Token），然后每次点菜都要出示这张卡（在后续请求中携带Token）。如果卡丢了，你就点不了菜了。

POST /api/login {username, password} 2. 返回 {token: "abc123xyz"} 3. GET /api/orders Header: Authorization: Bearer abc123xyz 4. 返回订单列表 5. POST /api/orders Header: Authorization: Bearer abc123xyz {productId, quantity} 6. 返回创建的订单

实战：登录后获取 Token 并在后续请求中使用

Step 1: 登录请求 → 提取 Token

复制代码 
添加 Post-Processor → JSON Extractor
- Reference Name: token
- JSON Path: $.data.accessToken
- Match Numbers: 1
- Default Value: TOKEN_NOT_FOUND

Step 2: 在后续请求中使用 Token

复制代码 
添加 HTTP Header Manager（放在 Thread Group 级别）
- Name: Authorization
- Value: Bearer ${token}

Step 3: 提取更多变量（如用户ID）

复制代码 
添加 JSON Extractor
- Reference Name: userId
- JSON Path: $.data.user.id

Step 4: 在后续请求中使用 userId

复制代码 
GET /api/users/${userId}/profile
常见关联场景
场景 提取方式 提取内容
登录获取Token JSON Extractor $.data.token
获取动态ID JSON Extractor $.data.orderId
从CSRF Token Regex Extractor <meta name="csrf" content="(.+?)">
分页参数 JSON Extractor $.data.nextPageToken
Session ID Regex Extractor JSESSIONID=(\w+)

5.4 断言（验证响应）

餐厅比喻 ：断言就像美食评论家------每次上菜后都要评价：这道菜是不是我点的？温度对不对？分量够不够？

所有用户同时发请求

= 开门瞬间所有人冲进来

不真实！
有定时器
用户按节奏发请求

= 顾客陆续到来

真实场景！

实战：配置合理的定时器
复制代码 
场景：模拟真实用户浏览行为

推荐配置：
Thread Group → Add → Timer → Gaussian Random Timer
- Delay (deviation): 1000（毫秒）
- Range (offset): 2000（毫秒）
→ 实际等待时间 = 1000 + 随机(0~2000) 毫秒
→ 大部分请求间隔在 1000~3000ms 之间
→ 符合正态分布，模拟真实用户行为

不同场景的定时器推荐：

场景 推荐定时器 配置
浏览页面 Gaussian Random Timer 1000~3000ms
提交表单 Uniform Random Timer 500~1500ms
API 调用 Constant Timer 100~500ms
突发压力 Synchronizing Timer 50个用户同步
精确吞吐量 Precise Throughput Timer 60次/分钟

Step 8: 添加监听器
复制代码 
Thread Group 下添加以下监听器：

1. Aggregate Report（聚合报告）
   → 查看每个事务的统计数据

2. Response Times Over Time
   → 查看响应时间趋势

3. Transactions per Second
   → 查看 TPS 趋势

4. Summary Report（汇总报告）
   → 快速查看总体指标

5. View Results Tree（调试用）
   → 压测时建议禁用！

性能测试报告模板
复制代码 
=== 电商系统性能测试报告 ===

一、测试环境
- 服务器：4C8G × 3 台
- 数据库：MySQL 8.0 主从
- 缓存：Redis 6.0 集群
- JMeter：5.6.3，4C8G，非GUI模式

二、测试场景
- 并发用户：1000
- 启动时间：120秒
- 持续时间：600秒
- 定时器：Gaussian Random 500~1500ms

三、测试结果
| 接口 | TPS | Avg(ms) | 90%(ms) | 99%(ms) | Error% |
|------|-----|---------|---------|---------|--------|
| 登录 | 52 | 180 | 350 | 680 | 0.02% |
| 浏览商品 | 210 | 85 | 180 | 420 | 0.01% |
| 搜索商品 | 95 | 220 | 480 | 950 | 0.08% |
| 下单支付 | 78 | 450 | 880 | 1800 | 0.05% |
| 查看订单 | 105 | 65 | 130 | 280 | 0.01% |

四、结论
- 所有接口 TPS 达标 ✅
- 90% 响应时间达标 ✅
- 错误率均低于 0.1% ✅
- 下单接口 99% 线偏高，建议优化

五、建议
1. 下单接口增加 Redis 缓存
2. 数据库添加读写分离
3. 支付接口增加异步处理

第7章 JMeter 分布式压测

7.1 为什么需要分布式压测？

餐厅比喻：如果一家餐厅要测试能否接待 10000 个顾客，一个服务员（一台机器）可能忙不过来。你需要雇佣多个服务员（多台机器），每个人负责一部分顾客，然后汇总结果。

7.3 配置步骤

Step 1: 所有节点安装 JMeter
bash 复制代码 
# 在 Master 和所有 Slave 上执行相同操作

# 1. 安装 JDK 17
sudo apt install -y openjdk-17-jdk

# 2. 下载安装 JMeter
wget https://dlcdn.apache.org/jmeter/binaries/apache-jmeter-5.6.3.tgz
tar -xzf apache-jmeter-5.6.3.tgz -C /opt/
export JMETER_HOME=/opt/apache-jmeter-5.6.3
export PATH=$JMETER_HOME/bin:$PATH

# 3. 安装插件管理器（所有节点）
cp jmeter-plugins-manager-1.9.jar $JMETER_HOME/lib/ext/

# 4. 确保所有节点的 JMeter 版本和插件完全一致！
jmeter --version
Step 2: 配置 Slave 节点
bash 复制代码 
# 编辑 Slave 的 JMETER_HOME/bin/jmeter.properties

# 1. 设置 Server 端口（默认 1099）
server_port=1099

# 2. 设置 Server 主机（0.0.0.0 允许所有IP连接）
server.rmi.localport=1099

# 3. 如果有防火墙，需要开放端口
sudo firewall-cmd --add-port=1099/tcp --permanent
sudo firewall-cmd --reload
Step 3: 启动 Slave 服务
bash 复制代码 
# Linux/Mac - 启动 Slave 服务
cd /opt/apache-jmeter-5.6.3/bin
./jmeter-server

# Windows - 启动 Slave 服务
jmeter-server.bat

# 如果需要指定 JVM 参数
JVM_ARGS="-Xms2g -Xmx4g" ./jmeter-server

# 后台运行（Linux）
nohup ./jmeter-server > jmeter-server.log 2>&1 &

# 验证 Slave 是否启动
netstat -an | grep 1099
# 应该看到 LISTENING 状态
Step 4: 配置 Master 节点
bash 复制代码 
# 编辑 Master 的 JMETER_HOME/bin/jmeter.properties

# 添加 Slave IP 列表
remote_hosts=192.168.1.101:1099,192.168.1.102:1099,192.168.1.103:1099,192.168.1.104:1099

# 或者编辑 JMETER_HOME/bin/remote_hosts（一行一个IP）
# 192.168.1.101
# 192.168.1.102
# 192.168.1.103
# 192.168.1.104
Step 5: 从 Master 启动分布式测试
bash 复制代码 
# GUI 模式启动（调试用）
jmeter
# 菜单：Run → Remote Start → 选择 Slave 节点
# 或 Run → Remote Start All

# 非GUI模式启动（正式压测）
# 启动所有 Slave
jmeter -n -t test_plan.jmx -r -l results.jtl

# 启动指定 Slave
jmeter -n -t test_plan.jmx -R 192.168.1.101:1099,192.168.1.102:1099 -l results.jtl

# 参数说明：
# -r : 启动 remote_hosts 中所有 Slave
# -R : 启动指定的 Slave（逗号分隔）

WebDriver
启动真实浏览器
执行JavaScript
渲染完整页面
速度慢
资源消耗高
HTTP Sampler
只发送HTTP请求
不执行JavaScript
不渲染页面
速度快
资源消耗低

使用场景：

  • 需要测试前端渲染性能
  • 需要测试 JavaScript 逻辑
  • 需要模拟真实浏览器行为
  • 需要截图或获取页面 DOM

注意：WebDriver 测试非常消耗资源，每个线程需要一个浏览器实例。建议并发数不超过 10。

8.5 其他实用插件

Dummy Sampler（调试利器）
复制代码 
用途：快速调试脚本逻辑，不需要真实服务器

配置：
├── Sampler Name: 模拟登录响应
├── Response Data: {"code":200,"data":{"token":"test_token_123"}}
├── Response Code: 200
├── Response Time: ${__Random(100,500)}（随机响应时间）
└── Status: OK

使用场景：
1. 在没有测试环境时调试脚本
2. 验证参数化和关联逻辑
3. 演示和培训
Synthesis Report（综合报告）
复制代码 
用途：生成更详细的 HTML 报告

特点：
- 比 JMeter 自带报告更美观
- 包含更多图表
- 支持自定义报告模板
- 可以对比多次测试结果

第9章 命令行执行与 CI/CD 集成

9.1 命令行执行详解

餐厅比喻 ：GUI 模式就像手动经营餐厅 ------你站在大堂里亲自指挥。命令行模式就像设定好自动运营程序------你写好运营手册，让系统自动执行。
渲染错误: Mermaid 渲染失败: Lexical error on line 8. Unrecognized text. ...ubgraph "非GUI模式（推荐）"] E"命令行执行" -----------------------^

完整命令参数
bash 复制代码 
jmeter [options] [JMX file]

# 核心参数
-n                    # 非GUI模式
-t testplan.jmx       # 指定测试计划文件
-l results.jtl         # 指定结果输出文件
-e                    # 测试结束后生成HTML报告
-o output_dir         # HTML报告输出目录
-r                    # 启动所有远程Slave
-R server_list        # 启动指定远程Slave

# JVM 参数
-J HEAP="-Xms4g -Xmx8g"    # 设置堆内存
-J java.awt.headless=true   # 无头模式

# 日志参数
-L [category=]level         # 设置日志级别
-j log_file                 # 日志输出文件

# 属性覆盖
-D property=value            # 覆盖JMeter属性
-J jmeter.property=value     # 覆盖JMeter属性
-J user.properties=value    # 覆盖用户属性

# 其他
-H                          # 显示帮助信息
-v                          # 显示版本信息
常用命令示例
bash 复制代码 
# 1. 基本非GUI执行
jmeter -n -t my_test.jmx -l results.jtl

# 2. 执行并生成HTML报告
jmeter -n -t my_test.jmx -l results.jtl -e -o report/

# 3. 分布式执行
jmeter -n -t my_test.jmx -r -l results.jtl

# 4. 指定Slave执行
jmeter -n -t my_test.jmx -R 192.168.1.101,192.168.1.102 -l results.jtl

# 5. 覆盖线程数和持续时间（无需修改JMX文件）
jmeter -n -t my_test.jmx -l results.jtl \
  -J threads=500 \
  -J duration=600 \
  -J rampup=60

# 6. 指定JVM内存
jmeter -n -t my_test.jmx -l results.jtl \
  -J HEAP="-Xms4g -Xmx8g -XX:+UseG1GC"

# 7. 从已有JTL生成HTML报告
jmeter --generate-html report/ --input-jtl results.jtl
在JMX中使用属性变量
xml 复制代码 
<!-- 在 JMX 文件中使用 ${__P(property, default)} 引用属性 -->
<ThreadGroup>
  <stringProp name="ThreadGroup.num_threads">${__P(threads,100)}</stringProp>
  <stringProp name="ThreadGroup.ramp_time">${__P(rampup,10)}</stringProp>
</ThreadGroup>
复制代码 
这样就可以通过命令行动态修改参数，无需修改 JMX 文件：
jmeter -n -t test.jmx -l results.jtl -Jthreads=500 -Jrampup=60

9.2 Jenkins CI/CD 集成

餐厅比喻 ：CI/CD 集成就像自动化巡检系统------每次有新菜品上线，自动请一批"神秘顾客"来品尝，如果味道不对就自动报警。

ms",verdana,arial,sans-serif;} JMeter 最佳实践
脚本设计
使用合理的定时器
避免过度使用断言
合理使用参数化
使用事务控制器
关联要准确
执行策略
始终使用非GUI模式
分布式压测
分阶段加压
先调试后压测
资源管理
调整JVM内存
禁用不必要的监听器
使用CSV而非内存变量
控制线程数
结果分析
关注90%线而非平均值
使用HTML报告
保存原始JTL文件
多次测试取平均值
维护管理
版本控制JMX文件
模块化脚本
文档化测试场景
定期更新JMeter版本

1. 脚本编写最佳实践
复制代码 
✅ DO（推荐做法）：
├── 使用 Throughput Controller 控制业务比例
├── 使用 Transaction Controller 统计事务时间
├── 使用 Gaussian Random Timer 模拟真实用户
├── 使用 JSR223 + Groovy（而非 BeanShell）
├── 使用 CSV Data Set Config 进行参数化
├── 使用 JSON Path 提取 JSON 响应
├── 在非GUI模式下执行压测
├── 将 JMX 文件纳入版本控制
└── 使用变量管理环境配置

❌ DON'T（避免做法）：
├── 不要在压测时启用 View Results Tree
├── 不要使用 Constant Timer 模拟真实用户
├── 不要在压测时使用 Functional Mode
├── 不要忽略 Ramp-up 时间（设为0）
├── 不要使用 BeanShell（性能差）
├── 不要在 Sampler 中硬编码数据
├── 不要忽略错误率
├── 不要只看平均响应时间
└── 不要在 GUI 模式下跑大规模压测
2. 性能优化技巧
groovy 复制代码 
// ✅ 推荐：JSR223 + Groovy（勾选 Cache compiled script）
// 性能比 BeanShell 快 10 倍以上！

// JSR223 PreProcessor - Groovy
def startTime = System.currentTimeMillis()
// ... 你的逻辑 ...
def elapsed = System.currentTimeMillis() - startTime
log.info("处理耗时: ${elapsed}ms")

// ❌ 避免：BeanShell（每次都要解释执行）
// 性能差，不推荐

10.2 常见问题与解决方案

问题1：内存溢出 (OutOfMemoryError)
复制代码 
现象：
java.lang.OutOfMemoryError: Java heap space

原因：
1. JVM 堆内存不够
2. 监听器保存了太多响应数据
3. 脚本中创建了大量对象

解决方案：
1. 增大 JVM 内存
   HEAP="-Xms4g -Xmx8g"
   
2. 压测时禁用 View Results Tree
   只保留 Aggregate Report
   
3. 在 Listener 中限制保存的数据量
   Configure → 只保存错误样本
   
4. 使用 JSR223 脚本时注意释放资源
问题2：CPU 使用率过高
复制代码 
现象：
JMeter 进程 CPU 100%，但吞吐量很低

原因：
1. 线程数太多（超过 CPU 核心数太多）
2. 使用了 BeanShell 脚本
3. 正则表达式太复杂
4. 启用了太多监听器

解决方案：
1. 减少单机线程数（推荐 200~500）
2. 改用 JSR223 + Groovy
3. 优化正则表达式
4. 使用分布式压测
5. 禁用不必要的监听器
问题3：响应时间不准确
复制代码 
现象：
JMeter 报告的响应时间比实际用户体验慢很多

原因：
1. 没有使用定时器（请求间隔为0）
2. 服务器端有缓存
3. DNS 解析耗时
4. SSL 握手耗时

解决方案：
1. 添加合理的定时器
2. 使用 HTTP Cache Manager
3. 在 DNS Config 中配置 DNS 服务器
4. 使用 HTTP Request Defaults 配置 Keep-Alive
5. 注意区分：
   - JMeter 响应时间 = 从发送请求到收到完整响应
   - 用户体验时间 = 还包括页面渲染时间
问题4：分布式测试连接失败
复制代码 
现象：
java.rmi.ConnectException: Connection refused

排查步骤：
1. 检查 Slave 的 jmeter-server 是否启动
   ps aux | grep jmeter-server
   
2. 检查防火墙是否开放端口
   sudo firewall-cmd --list-ports
   sudo firewall-cmd --add-port=1099/tcp
   
3. 检查 remote_hosts 配置是否正确
   cat jmeter.properties | grep remote_hosts
   
4. 检查网络连通性
   telnet slave_ip 1099
   
5. 检查 JDK 版本是否一致
   java -version（Master 和 Slave）
   
6. 检查 JMeter 版本是否一致
   jmeter --version
问题5：CSV 数据读取问题
复制代码 
现象：
所有用户使用了相同的数据 / 数据读取不到

原因：
1. Sharing mode 设置不正确
2. CSV 文件路径不对
3. 变量名与 CSV 列头不匹配
4. 文件编码问题

解决方案：
1. Sharing mode 选择：
   - All threads: 所有线程共享（轮流使用不同行）
   - Current thread group: 当前线程组共享
   - Current thread: 每个线程独立使用（每个用户从第一行开始）
   
2. 使用绝对路径或相对于 JMX 的路径
   
3. 确保 Variable Names 与 CSV 列头一致

附录 B：Groovy 脚本常用代码片段

B.1 生成随机数据

groovy 复制代码 
// 随机手机号
def prefix = ['130','131','132','133','134','135','136','137','138','139']
def phone = prefix[new Random().nextInt(prefix.size())] + (100000000 + new Random().nextInt(900000000))
vars.put("phone", phone.toString())

// 随机邮箱
def domains = ['qq.com', '163.com', 'gmail.com', 'outlook.com']
def email = "test${System.currentTimeMillis()}@${domains[new Random().nextInt(domains.size())]}"
vars.put("email", email)

// 随机身份证号（简化版）
def areaCode = '110101'
def year = 1980 + new Random().nextInt(20)
def month = String.format('%02d', 1 + new Random().nextInt(12))
def day = String.format('%02d', 1 + new Random().nextInt(28))
def seq = String.format('%03d', new Random().nextInt(999))
def idCard = "${areaCode}${year}${month}${day}${seq}X"
vars.put("idCard", idCard)

// UUID
vars.put("requestId", UUID.randomUUID().toString())

// 时间戳
vars.put("timestamp", System.currentTimeMillis().toString())

B.2 数据处理

groovy 复制代码 
// JSON 解析
import groovy.json.JsonSlurper

def response = prev.getResponseDataAsString()
def json = new JsonSlurper().parseText(response)

// 提取字段
vars.put("userId", json.data.user.id.toString())
vars.put("userName", json.data.user.name)

// 列表遍历
json.data.items.each { item ->
    log.info("商品ID: ${item.id}, 名称: ${item.name}")
}

// 条件判断
if (json.code == 200) {
    log.info("请求成功")
    vars.put("status", "success")
} else {
    log.warn("请求失败: ${json.message}")
    vars.put("status", "failed")
}

B.3 文件操作

groovy 复制代码 
// 读取文件
def file = new File('/path/to/data.json')
def content = file.text

// 写入文件
new File('/path/to/output.txt').append("${vars.get("token")}\n")

// 读取CSV
def csv = new File('/path/to/data.csv')
