JCStress 入门篇

1、介绍

jcstress是一个测试框架，用于测试 JVM、类库和硬件中并发支持的正确性。

2、使用步骤

2.1、引入Maven

<dependency>
    <groupId>org.openjdk.jcstress</groupId>
    <artifactId>jcstress-core</artifactId>
    <version>0.16</version>
</dependency>

<dependency>
    <groupId>org.openjdk.jcstress</groupId>
    <artifactId>jcstress-samples</artifactId>
    <version>0.11</version>
</dependency>

2.2 安装JCStress插件

2.3 编写测试代码

@JCStressTest

// These are the test outcomes.
@Outcome(id = "1, 1", expect = Expect.ACCEPTABLE_INTERESTING, desc = "Both actors came up with the same value: atomicity failure.")
@Outcome(id = "1, 2", expect = Expect.ACCEPTABLE, desc = "actor1 incremented, then actor2.")
@Outcome(id = "2, 1", expect = Expect.ACCEPTABLE, desc = "actor2 incremented, then actor1.")

// This is a state object
@State
public class APISample_01_Simple {

    int v;

    @Actor
    public void actor1(II_Result r) {
        r.r1 = ++v; // record result from actor1 to field r1
    }

    @Actor
    public void actor2(II_Result r) {
        r.r2 = ++v; // record result from actor2 to field r2
    }

}

2.4 运行

mvn clean verify
