接口性能测试--JMeter
1.JMeter Java Sampler介绍 setupTest做些初始化的工作，每个线程只执行一次 teardownTest做些清理工作，每个线程只执行一次
setupTest做些初始化的工作，每个线程只执行一次
teardownTest做些清理工作，每个线程只执行一次
runTest具体的测试执行工作，每个并发每次循环都将执行一次
SampleResult记录测试结果，result.sampleStart()一个事务开始，result.sampleEnd()一个事务结束
main方法用于调试

2.多接口性能测试
按照上面的方法进行测试，每个需要测试的接口和场景都需要写一个这样的测试类，对于有些具有相似初始化，清理等工作，只有具体的那行事务代码不一样的情况，会有很多重复的工作。如下：可以考虑采用反射的方式来解决这个问题，尤其是业务非常类似的接口和场景。当然，反射会带来压力机的性能消耗，但是这个可以通过调整JMeter的JVM参数和增加JMeter实例来解决。
1)利用反射后的结构如下：
2)AbstractServiceClient是一个抽象基类
package com . xxx . yyy . perf . base;
import java.lang.reflect.Method;
import org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient;
import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext;
import org.apache.jmeter.samplers.SampleResult;
/**
* Comment of AbstractServiceClient
* @author flynewton
*/
public abstract class AbstractServiceClient extends AbstractJavaSamplerClient {
public Object invokeTest( String testName , JavaSamplerContext context ,SampleResult sample) {
Method [] methods = this . getClass (). getMethods();
for ( Method m : methods) {
if ( m . getName (). equalsIgnoreCase( testName)) {
try {
return m . invoke( this , context , sample);
} catch ( Throwable t) {
this . getLogger (). error( "execute method:" + testName + " falied" , t);
}
}
}
return null;
}
}

3)GetPersonTest为某一类具有相似业务场景的测试类 其中 getDefaultParameters方法设置默认参数：test传入具体要执行的 测试方法 ;info传入日志级别，利用main方法
3)GetPersonTest为某一类具有相似业务场景的测试类
其中 getDefaultParameters方法设置默认参数：test传入具体要执行的测试方法;info传入日志级别，利用main方法进行调试时设置为true，真正进行性能测试的时候设置为false
