如何在IDEA中使用jcstress进行并发压力测试

如何在IDEA中使用jcstress进行并发压力测试

在研究高并发的时候，偶然发现这个，还是有点好用的。

• 测试类

  @JCStressTest
  @Outcome(id = {"1","4"}, expect = Expect.ACCEPTABLE,desc = "ok")
  @Outcome(id = "0",expect = Expect.ACCEPTABLE_INTERESTING,desc = "danger")
  @State
  public class Test03Orderliness {
      int num = 0;
      boolean ready = false;
      // 线程一执行的代码
      @Actor
      public void actor1(I_Result r) {
          if(ready) {
              r.r1 = num + num;
          } else {
              r.r1 = 1;
          }
      }
      @Actor
      public void actor2(I_Result r) {
          num = 2;
          ready = true;
      }
  }
