Benchmarking Redis Key‑Value Inserts with FunTester: Java & Groovy Test Cases

The author builds on a previous FunTester Redis stress‑test preparation and moves into the implementation phase, focusing on a test case that repeatedly inserts key‑value entries into Redis.

Test Design

The approach mirrors earlier stress tests: a single thread repeatedly performs an operation, a thread pool runs multiple tasks concurrently, and the framework aggregates the results. Connection handling follows a pattern similar to HTTP connection pooling—acquire a connection, execute operations, then release it.

Java Test Case

/**
 * redis添加key-value性能测试用例
 */
public class RedisPerTest extends SourceCode {
    public static final String host = "FunTester隐藏地址";
    public static final int port = 6379;
    public static RedisBase drive;

    public static void main(String[] args) {
        drive = new RedisBase(host, port);
        drive.index = 1;
        RUNUP_TIME = 0;
        drive.set("fun" + StringUtil.getString(10), "FunTester", 100);
        FunTester funTester = new FunTester(100);
        Concurrent concurrent = new Concurrent(funTester, 400, "redis添加key-value性能测试用例");
        concurrent.start();
        drive.close();
    }

    private static class FunTester extends FixedThread {
        public FunTester(int limit) {
            super(null, limit, true);
        }

        @Override
        protected void doing() throws Exception {
            drive.set("fun" + StringUtil.getString(10), "FunTester", 100);
        }

        @Override
        public ThreadBase clone() {
            return new FunTester(limit);
        }
    }
}

The Groovy version follows the same logic and is omitted for brevity.

Conclusion

The test demonstrates a straightforward way to benchmark Redis insert performance using FunTester. The author plans to extend the work to multi‑operation scenarios, set‑type values, and Redis atomic increments. Although real‑world projects rarely test Redis directly, maintaining such skills can be valuable when the need arises.
