Jmeter接口测试问题整理（一）

BeanShell调用第三方Jar包问题集合

问题一：第三方Jar包的方法调用失败

BeanShell脚本： 

import dataProducer.mongodb.*;
import org.apache.commons.lang.StringUtils;
log.info("调用第三方Jar包，MongoDB创建colletion>>>");
String url="172.16.8.193:27017";
String database="dtstack";
log.info("close MongoDB connection>>>");
MongoDBDataProducer.close();//关闭MongoDB资源
MongoDBDataProducer.connectNoAuth(url,database);

错误日志： 

2020-08-13 10:38:00,414 INFO o.a.j.t.JMeterThread: Thread started: 数栈-StreamApp接口 1-1
2020-08-13 10:38:00,416 INFO o.a.j.u.BeanShellTestElement: 调用第三方Jar包，MongoDB创建colletion>>>

2020-08-13 10:38:00,420 ERROR o.a.j.u.BeanShellInterpreter: Error invoking bsh method: eval    Sourced file: inline evaluation of: ``import dataProducer.mongodb.*; import org.apache.commons.lang.StringUtils;  log. . . . '' : Method Invocation MongoDBDataProducer.connectNoAuth
2020-08-13 10:38:00,420 WARN o.a.j.p.j.s.BeanShellSampler: Exception executing script. org.apache.jorphan.util.JMeterException: Error invoking bsh method: eval    Sourced file: inline evaluation of: ``import dataProducer.mongodb.*; import org.apache.commons.lang.StringUtils;  log. . . .

2020-08-13 10:38:00,420 INFO o.a.j.s.FileServer: Stored: ./login.csv

排查问题步骤：

  1. 排除语法错误问题
  2. 日志中可以看出 connectNoAuth 方法调用失败，排查是否调到 connectNoAuth 这个方法：将 MongoDBDataProducer.connectNoAuth(url,database); 改成 MongoDBDataProducer.connectNoAuth(url,1，database); 再运行，报错如下： 
2020-08-13 10:47:39,948 INFO o.a.j.t.JMeterThread: Thread started: 数栈-StreamApp接口 1-1
2020-08-13 10:47:39,949 INFO o.a.j.u.BeanShellTestElement: 调用第三方Jar包，MongoDB创建colletion>>>
2020-08-13 10:47:39,950 INFO o.a.j.u.BeanShellTestElement: close MongoDB connection>>>
2020-08-13 10:47:39,955 ERROR o.a.j.u.BeanShellInterpreter: Error invoking bsh method: eval Sourced file: inline evaluation of: ``import dataProducer.mongodb.*; import org.apache.commons.lang.StringUtils;  log. . . . '' : Error in method invocation: Static method connectNoAuth( java.lang.String, int, java.lang.String ) not found in class'dataProducer.mongodb.MongoDBDataProducer'
2020-08-13 10:47:39,955 WARN o.a.j.p.j.s.BeanShellSampler: Exception executing script. org.apache.jorphan.util.JMeterException: Error invoking bsh method: eval Sourced file: inline evaluation of: ``import dataProducer.mongodb.*; import org.apache.commons.lang.StringUtils;  log. . . . '' : Error in method invocation: Static method connectNoAuth( java.lang.String, int, java.lang.String ) not found in class'dataProducer.mongodb.MongoDBDataProducer'
2020-08-13 10:47:39,955 INFO o.a.j.s.FileServer: Stored: ./login.csv

可反向推断原先 MongoDBDataProducer.connectNoAuth(url,database); 是调到的 \3. 排查是否是 connectNoAuth 方法报错，只是jmeter未捕获到异常信息；使用try catch来捕获异常： 

try {
    MongoDBDataProducer.connectNoAuth(url,database);
catch (Throwable ex) {
    log.error("Failed to do this or that", ex);
}

问题二：出现 java.lang.NoSuchMethodError: com.mongodb.MongoClient.getDatabase(Ljava/lang/String;)Lcom/mongodb/client/MongoDatabase; 错误

BeanShell脚本： 

import dataProducer.mongodb.*;
import org.apache.commons.lang.StringUtils;
log.info("调用第三方Jar包，MongoDB创建colletion>>>");
String url="172.16.8.193:27017";

log.info("close MongoDB connection>>>");
MongoDBDataProducer.close();//关闭MongoDB资源
try {
    MongoDBDataProducer.connectNoAuth(url,database);
catch (Throwable ex) {
    log.error("Failed to do this or that", ex);
}
