simperf性能测试工具
Simperf 是一个简单的性能测试工具,它提供了一个多线程测试框架
Example:
1. 在代码里使用Simperf
Simperf perf = new Simperf(50, 2000, 1000, 
    new SimperfThreadFactory() {
        public SimperfThread newThread() {
            return new SimperfThread();
        }
    });
// 设置结果输出文件,默认 simperf-result.log
perf.getMonitorThread().setLogFile("simperf.log");
// 开始性能测试
perf.start();
 
2. 在命令行里使用Simperf
public class SimperfCommandTest {
    public static void main(String[] args) {
        SimperfCommand simCommand = new SimperfCommand(args);
        Simperf perf = simCommand.create();
        if (perf == null) {
            // 参数解析失败时会返回null
            System.exit(-1);
        }
        perf.start(new SimperfThreadFactory() {
            public SimperfThread newThread() {
                return new SimperfThread();
            }
        });
    }
}
 
执行命令:
java SimperfCommandTest -t 10 -c 10 -i 1000 参数说明: usage: SimperfCommand options -c,--count [*] number of each thread requests count -i,--interval [ ] interval of print messages, default 1000 -j [ ] generate jtl report -l,--log [ ] log filename -m,--maxtps [ ] max tps -t,--thread [*] number of thread count
3. 在Junit4里使用Simperf
public class SimperfTestCaseTest extends SimperfTestCase {
    private Random              rand;
    @Test
    @Simperf(thread = 2, count = 5, interval = 1000)
    public void testXxx() {
        try {
            Thread.sleep(1000);
        } catch (Exception e) {
        }
        boolean result = rand.nextInt(10) > 1;
        Assert.assertTrue("随机生成结果", result);
    }
