最近須要對改造的redis緩存接口作壓力測試,使用了開源壓力測試工具JMeter,分享一下本身的使用經驗,但願能對須要進行壓力測試的開發同窗有所幫助。java
JMeter介紹redis
JMeter是Apache軟件基金會下的一款開源壓力測試工具,官方網址是:http://jmeter.apache.org/。JMeter能夠測試靜態、動態資源的性能,這些資源包括文件、Servlets 、Perl腳本、Java對象、數據庫、FTP服務器等,並生成圖形報告。JMeter使用Java開發,既支持可視化界面操做,也支持命令行操做。spring
Java請求測試(界面操做)數據庫
因爲須要對改造的redis緩存接口測試,所以使用了JMeter的Java請求測試,安裝和使用步驟以下所示(以Windows操做系統爲例,並默認已安裝、配置Java運行環境)。apache
1)從官網上下載JMeter並解壓,例如解壓至C:\apache-jmeter-2.9。緩存
2)配置JMeter環境變量,增長變量JMETER_HOME,值爲「C:\apache-jmeter-2.9」,修改變量CLASSPATH,增長「%JMETER_HOME%\lib\ext\ApacheJMeter_core.jar;% JMETER_HOME%\lib\jorphan.jar;%JMETER_HOME%\lib\logkit-1.2.jar;」服務器
3)執行JMeter目錄下的bin\jmeter.bat,顯示JMeter界面說明安裝成功。併發
4)新建Java工程,在該工程中,引入JMeter目錄下lib中的jar包,繼承JMeter的AbstractJavaSamplerClient類,在子類中重寫setupTest、teardownTest、getDefaultParameters、runTest方法,實現對緩存接口的get、set、hGet、hSet方法進行測試,子類代碼以下所示。app
package com.sohu.cms.test; 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.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.sohu.cms.datacache.DataCache; import com.sohu.cms.datacache.DataCacheManager; /** * 繼承jmeter的AbstractJavaSamplerClient類, * 重寫setupTest、teardownTest、getDefaultParameters、runTest方法 * 對緩存接口的get、set、hGet、hSet方法進行測試 * @author wang * */ public class TestDataCacheClient extends AbstractJavaSamplerClient{ private static long start = 0; private static long end = 0; private static DataCacheManager dataCacheManager; private static DataCache dataCache; private static int size = 8192; private static String method = "get"; private static Object key = "TEST_KEY"; private static Object field = "TEST_FIELD"; private static Object value = new Byte[size]; //此處初始化咱們改造的redis緩存接口dataCache static { ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"applicationContext.xml"}); dataCacheManager = (DataCacheManager) context.getBean("dataCacheManager"); dataCache = dataCacheManager.getObjectDataCache(); } /** * 測試開始 */ public void setupTest(JavaSamplerContext arg0) { start = System.currentTimeMillis(); } /** * 測試結束 */ public void teardownTest(JavaSamplerContext arg0) { end = System.currentTimeMillis(); System.out.println("[method=" + method + "] [size=" + size + "] [time:" + (end - start) / 1000); } /** * 添加參數默認值,參數默認值會在界面中顯示 */ public Arguments getDefaultParameters() { //添加兩個參數, //size爲測試value值的字節大小,默認爲8192字節 //method爲須要進行測試的緩存接口方法,默認爲get Arguments args = new Arguments(); args.addArgument("size", "8192"); args.addArgument("method","get"); return args; } /** * 測試 */ public SampleResult runTest(JavaSamplerContext arg0) { //獲取界面或測試計劃配置文件(jmx)中傳入的參數 if (arg0.getParameter("method") != null) method = arg0.getParameter("method"); if (arg0.getIntParameter("size") > 0) size = arg0.getIntParameter("size"); value = new Byte[size]; SampleResult sr = new SampleResult(); try { boolean result = true; //根據傳入的method參數測試相應的緩存接口方法 if (method.equals("get")){ //測試用例的核心邏輯 //測試用例開始 sr.sampleStart(); //測試用例執行 result = get(); //測試用例結果 sr.setSuccessful(result); //測試用例結束 sr.sampleEnd(); } else if (method.equals("set")) { sr.sampleStart(); result = set(); sr.setSuccessful(result); sr.sampleEnd(); } else if (method.equals("hGet")) { sr.sampleStart(); result = hGet(); sr.setSuccessful(result); sr.sampleEnd(); } else if (method.equals("hSet")) { sr.sampleStart(); result = hSet(); sr.setSuccessful(result); sr.sampleEnd(); } } catch (Exception e) { e.printStackTrace(); } return sr; } /** * 緩存接口get方法測試用例 * @return */ public boolean get() { boolean result = true; try { dataCache.get(key); } catch (Exception e) { System.out.println(e); result = false; } return result; } /** * 緩存接口set方法測試用例 * @return */ public boolean set() { boolean result = true; try { dataCache.put(key, value); } catch (Exception e) { System.out.println(e); result = false; } return result; } /** * 緩存接口hGet方法測試用例 * @return */ public boolean hGet() { boolean result = true; try { dataCache.hGet(key, field); } catch (Exception e) { System.out.println(e); result = false; } return result; } /** * 緩存接口hSet方法測試用例 * @return */ public boolean hSet() { boolean result = true; try { result = dataCache.hSet(key, field, value); } catch (Exception e) { System.out.println(e); result = false; } return result; } }
5)將工程以jar包形式導出,置於JMeter目錄lib\ext下,並將工程依賴的jar包置於JMeter目錄lib下,啓動JMeter。右鍵「測試計劃」添加「線程組」。右鍵「線程組」添加「Java請求」,右鍵「Java請求」添加「聚合報告」。ide
6)在「Java請求」中選擇所寫的測試類,並能夠設置相關參數,在「線程組」中能夠設置併發線程數和循環次數,點擊上方「啓動」按鈕開始測試,測試完成後,能夠在「聚合報告」中查看到測試結果。
Java請求測試(命令行操做)
JMeter也支持命令行操做,在服務器上進行測試時,咱們就採用了這種方式。一個簡單的JMeter命令行操做以下所示(在JMeter目錄bin下執行)。
Windows下: JMeter-n –t test.jmx -l result.jtl Linux下: ./jmeter.sh -n –t test.jmx -l result.jtl |
其中-n 表示命令行執行,test.jmx爲測試計劃配置文件,result.jtl爲測試結果。
可在界面中進行測試計劃配置,而後保存即可生成jmx格式文件,以下所示。

result.ftl爲按行輸出的測試執行結果,以下所示,可在界面操做的聚合報告導入該文件從而生成聚合報告。
