接口性能測試--JMeter

1.JMeter Java Sampler介紹 setupTest作些初始化的工做，每一個線程只執行一次 teardownTest作些清理工做，每一個線程只執行一次

　　1.JMeter Java Sampler介紹

　　setupTest作些初始化的工做，每一個線程只執行一次

　　teardownTest作些清理工做，每一個線程只執行一次

　　runTest具體的測試執行工做，每一個併發每次循環都將執行一次

　　SampleResult記錄測試結果，result.sampleStart()一個事務開始，result.sampleEnd()一個事務結束

　　main方法用於調試

　　2.多接口性能測試

　　按照上面的方法進行測試，每一個須要測試的接口和場景都須要寫一個這樣的測試類，對於有些具備類似初始化，清理等工做，只有具體的那行事務代碼不同的狀況，會有不少重複的工做。以下：能夠考慮採用反射的方式來解決這個問題，尤爲是業務很是相似的接口和場景。固然，反射會帶來壓力機的性能消耗，可是這個能夠經過調整JMeter的JVM參數和增長JMeter實例來解決。

　　1)利用反射後的結構以下：

　　2)AbstractServiceClient是一個抽象基類

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爲某一類具備類似業務場景的測試類 其中 getDefaultParameters方法設置默認參數：test傳入具體要執行的 測試方法 ;info傳入日誌級別，利用main方法

　　3)GetPersonTest爲某一類具備類似業務場景的測試類

　　其中 getDefaultParameters方法設置默認參數：test傳入具體要執行的測試方法;info傳入日誌級別，利用main方法進行調試時設置爲true，真正進行性能測試的時候設置爲false
