根据需求,产品部分功能采用thrift-RPC协议进行接口的增、删、改、查,前期采用Junit对其进行测试,为了提高RPC接口测试的简洁化和后期的性能测试需求,打算通过Jmeter的java类测试实现。
前期准备:
开发提供了IDL描述的Thrift文件:dataService.thrift,其中定义了相关接口函数及数据类型,如下:
enum VStatus {
ON,
OFF
} struct VData {
1: required string tablename;
2: required string time;
3: required string jsons;
4: optional VStatus status;
} struct VCondition {
1: required string tablename;
2: required i64 starttime;
3: required i64 endtime;
} service DataService {
string write(1: VData data);
string read(1: VCondition condition);
}
在本地部署thrift.exe并设置环境变量,之后在dataService.thrift所在的目录下执行:
<dependencies>
<dependency>
<groupId>org.apache.thrift</groupId>
<artifactId>libthrift</artifactId>
<version>0.11.0</version>
</dependency> <dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.8.2</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.8.2</version>
</dependency> </dependencies>
之后手动加载本地Jmeter版本目录\Jmeter_Home\lib\ext中的ApacheJMeter_core.jar和ApacheJMeter_java.jar作为外部依赖包(注:直接maven加载相关版本的依赖包执行时存在冲突)
将之前生成的4个java文件导入项目,设置包名为:com.test.thrift.api,在项目包名下创建ReadRPC.java类,根据Jmeter中java类要求需要继承 AbstractJavaSamplerClient,代码如下:
package com.test.RPCTest; import com.test.thrift.api.DataService;
import com.test.thrift.api.VCondition; import org.apache.jmeter.config.Arguments;
import org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient;
import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext;
import org.apache.jmeter.samplers.SampleResult;
import org.apache.thrift.protocol.TBinaryProtocol;
import org.apache.thrift.protocol.TProtocol;
import org.apache.thrift.transport.TSocket;
import org.apache.thrift.transport.TTransport; public class ReadRPC extends AbstractJavaSamplerClient{
private TTransport tTransport;
private DataService.Client dataService;
private TProtocol tProtocol;
private VCondition vCondition; @Override
public Arguments getDefaultParameters(){ //默认参数值,包括服务ip、端口、目标表、起止时间等
Arguments arguments=new Arguments();
arguments.addArgument("IP", "127.0.0.1");
arguments.addArgument("Port", "8888");
arguments.addArgument("TableName", "vle::test.trpc");
arguments.addArgument("StartTime", "1539752449");
arguments.addArgument("EndTime", "1539752449");
return arguments;
} @Override
public void setupTest(JavaSamplerContext context) { //初始化参数,并通过TTransport模式TBinaryProtocol二进制协议与服务端建立连接
// TODO Auto-generated method stub
String ip=context.getParameter("IP");
int port=context.getIntParameter("Port");
String tableName=context.getParameter("TableName");
long startTime=context.getLongParameter("StartTime");
long endTime=context.getLongParameter("EndTime");
tTransport=new TSocket(ip,port,30000);
vCondition=new VCondition();
try {
tTransport.open();
tProtocol=new tBinaryProtocol(tTransport);
dataService=new DataService.Client(tProtocol);
vCondition.setTablename(tableName);
vCondition.setStarttime(startTime);
vCondition.setEndtime(endTime);
} catch (Exception e) {
// TODO: handle exception
}
super.setupTest(context);
} @Override
public SampleResult runTest(JavaSamplerContext context) {
// TODO Auto-generated method stub
SampleResult sampleResult = new SampleResult();
sampleResult.setDataEncoding("utf8");
sampleResult.sampleStart();
try {
String msg=dataService.read(tCondition);//执行读操作,返回响应结果信息到msg if(null==msg){//为空判断
sampleResult.setSuccessful(false);
sampleResult.setResponseMessage("响应结果为空!");
sampleResult.setSampleLabel("RPC读取");
sampleResult.setResponseOK();
sampleResult.setResponseData("响应结果为空!");
sampleResult.setDataType(SampleResult.TEXT);
return sampleResult;
}
else {
sampleResult.setSuccessful(true);
sampleResult.setSampleLabel("RPC读取");
sampleResult.setResponseOK();
sampleResult.setResponseData(msg);
System.out.println("msg="+msg);
sampleResult.setDataType(SampleResult.TEXT);
return sampleResult;
} } catch (Exception e) {
// TODO: handle exception
sampleResult.setSuccessful(false);
e.printStackTrace();
}
finally{
sampleResult.sampleEnd();
}
return sampleResult;
} public void teardownTest(JavaSamplerContext context){
tTransport.close();//关闭连接
super.teardownTest(context);
} }
在main函数中调用ReadRPC相关函数,代码如下:
public static void main( String[] args )
{
JmeterRPC jrpc=new JmeterRPC();
jrpc.read(); } public void read(){
Arguments arguments=new Arguments();
arguments.addArgument("IP", "127.0.0.1");
arguments.addArgument("Port", "8888");
arguments.addArgument("TableName", "vle::test.trpc");
arguments.addArgument("StartTime", "1539752449");
arguments.addArgument("EndTime", "1539752449");
JavaSamplerContext context=new JavaSamplerContext(arguments);
ReadRPC rpc=new ReadRPC();
rpc.setupTest(context);
rpc.runTest(context);
rpc.teardownTest(context);
}
运行程序输出msg=[{".........相关响应数据.............."}]
调试成功后保存后,选中项目右键“Export”->“Java”->“Runnable JAR file”,点击“Next”,设置输出路径和依赖库,如下图所示:
备注:选择第一种方式将依赖包打在里面;
将打好的RPC.jar包拷贝到JMeter_Home\lib\ext下,启动jmeter控制台打印该jar信息,如下图所示:
启动完成后添加Java请求,显示读取类名,配置相关参数,如下图所示:
执行结果如下:
之后便可以通过该jar进行RPC相关接口测试,而且保证其他测试人员无需写代码便可进行测试。
