手寫java效能測試框架的實現範例

引言

之前寫過一個效能測試框架，只是針對單一的HTTP介面的測試，對於業務介面和非HTTP介面還無非適配，剛好前端時間工作中用到了，就更新了自己的測試框架，這次不再以請求為基礎，而是以方法為基礎，這樣就可以避免了單一性，有一個base類，然後其他的各種單一性請求在單獨寫一個適配類就好了，如果只是臨時用，直接重新實現base即可。

基礎類實現

下面是幾個實現過的基礎類：

package com.fun.frame.thead;
import com.fun.httpclient.ClientManage;
import com.fun.httpclient.FanLibrary;
import com.fun.httpclient.GCThread;
import org.apache.http.HttpStatus;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpRequestBase;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.io.IOException;
/**
 * http請求多執行緒類
 */
public class RequestThread extends ThreadBase {
    static Logger logger = LoggerFactory.getLogger(RequestThread.class);
    /**
     * 請求
     */
    public HttpRequestBase request;
    /**
     * 單請求多執行緒多次任務構造方法
     *
     * @param request 被執行的請求
     * @param times   每個執行緒執行的次數
     */
    public RequestThread(HttpRequestBase request, int times) {
        this.request = request;
        this.times = times;
    }
    @Override
    public void before() {
        request.setConfig(FanLibrary.requestConfig);
        GCThread.starts();
    }
    @Override
    protected void doing() throws Exception {
        getResponse(request);
    }
    @Override
    protected void after() {
        GCThread.stop();
    }
    /**
     * 多次執行某個請求，但是不記錄紀錄檔，記錄方法用 loglong
     * <p>此方法只適應與單個請求的重複請求，對於有業務聯絡的請求暫時不能適配</p>
     *
     * @param request 請求
     * @throws IOException
     */
    void getResponse(HttpRequestBase request) throws IOException {
        CloseableHttpResponse response = ClientManage.httpsClient.execute(request);
        String content = FanLibrary.getContent(response);
        if (response.getStatusLine().getStatusCode() != HttpStatus.SC_OK)
            logger.warn("響應狀態碼：{},響應內容：{}", content, response.getStatusLine());
        if (response != null) response.close();
    }
}

資料庫的實現

package com.fun.frame.thead;
import com.fun.interfaces.IMySqlBasic;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.sql.SQLException;
/**
 * 資料庫多執行緒類
 */
public class QuerySqlThread extends ThreadBase {
    private static Logger logger = LoggerFactory.getLogger(QuerySqlThread.class);
    String sql;
    IMySqlBasic base;
    public QuerySqlThread(IMySqlBasic base, String sql, int times) {
        this.times = times;
        this.sql = sql;
        this.base = base;
    }
    @Override
    public void before() {
        base.getConnection();
    }
    @Override
    protected void doing() throws SQLException {
        base.excuteQuerySql(sql);
    }
    @Override
    protected void after() {
        base.mySqlOver();
    }
}

        this(num);
        this.thread = thread;
    }
    /**

        executorService = Executors.newFixedThreadPool(num);
        countDownLatch = new CountDownLatch(num);
    }

    public PerformanceResultBean start() {
        long start = Time.getTimeStamp();
        for (int i = 0; i < num; i++) {
            ThreadBase thread = getThread(i);
            thread.setCountDownLatch(countDownLatch);
            executorService.execute(thread);
        }
        shutdownService(executorService, countDownLatch);
        long end = Time.getTimeStamp();
        logger.info("總計" + num + "個執行緒，共用時：" + Time.getTimeDiffer(start, end) + "秒！");
        return over();
    }

        } catch (InterruptedException e) {
            logger.warn("執行緒池關閉失敗！", e);
        }
    }
    private PerformanceResultBean over() {
        Save.saveLongList(allTimes, num);
        return countQPS(num);
    }
    ThreadBase getThread(int i) {
        if (threads == null) return thread;
        return threads.get(i);
    }
    /**
     * 計算結果
     * <p>此結果僅供參考</p>
     *
     * @param name 執行緒數
     */
    public static PerformanceResultBean countQPS(int name) {
        List<String> strings = WriteRead.readTxtFileByLine(Constant.LONG_Path + name + Constant.FILE_TYPE_LOG);
        int size = strings.size();
        int sum = 0;
        for (int i = 0; i < size; i++) {
            int time = SourceCode.changeStringToInt(strings.get(i));
            sum += time;
        }
        double v = 1000.0 * size * name / sum;
        PerformanceResultBean performanceResultBean = new PerformanceResultBean(name, size, sum / size, v);
        performanceResultBean.print();
        return performanceResultBean;
    }
}

redis實現類缺失，因為沒有遇到需要單獨實現的需求。

關於用程式碼還是用工具實現並行，我個人看法所有所長，單究其根本，必然是程式碼勝於工具，原因如下：門檻高，適應性強；貼近開發，利於調優。

效能測試，並行只是開始，只有一個好的開始才能進行效能資料分析，效能引數調優。所以不必拘泥於到底使用哪個工具那種語言，據我經驗來說：基本的測試需求都是能滿足的，只是實現的代價不同。

groovy是一種基於JVM的動態語言，我覺得最大的優勢有兩點

第一：於java相容性非常好，大部分時候吧groovy的檔案字尾改成java直接可以用，反之亦然。java的絕大部分庫，groovy都是可以直接拿來就用的。這還帶來了另外一個有點，學習成本低，非常低，直接上手沒問題，可以慢慢學習groovy不同於Java的語法；
第二：編譯器支援變得更好，現在用的intellij的ide，總體來說已經比較好的支援groovy語言了，寫起程式碼來也是比較順滑了，各種基於groovy的框架工具也比較溜，特別是Gradle構建工具，比Maven爽很多。
