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:

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();

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

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);
    }
}
