Automated Verification of Socket.IO Interfaces Using VerifyBean in Java/Groovy

The author explains the development of an automated testing script for Socket.IO interfaces, leveraging a multi‑functional JSON verification class called VerifyBean . Previously, socket responses were checked manually; the new approach validates responses programmatically.

Background links to earlier articles on socket interface development, WebSocket client encapsulation, Socket.IO client encapsulation, multi‑user testing practices, and the JSON verification class are provided for reference.

A note on Groovy operator overloading ( == ) highlights a subtle bug where equality checks may invoke Java's equals method when the code is packaged as a JAR, causing unexpected behavior and requiring debugging.

Source code for the test script is presented in full, showing how the teacher logs in, connects via a Socket , registers, joins and leaves a room, and then performs cross‑validation of received messages using two List collections and a 2‑second delay. The script utilizes the VerifyBean instances to define verification rules such as JSONPath matching and string containment.

    public static void main(String[] args) {

        def bean1 = new VerifyBean("contain|61951375269", EMPTY, "FunTester1")
        sv.addVerify(bean)
        sv.addVerify(bean1)
        sleep(2.0);
        def thread = new Thread(sv)
        thread.start()
        logger.info("脚本完成!")

        output(sv.vs*.result)

    }

    static class SV implements ISocketVerify {
        List
vs = new ArrayList<>()
        ScoketIOFunClient client
        SV(ScoketIOFunClient client) { this.client = client }
        @Override void initMsg(List
list) {}
        @Override boolean verify() { return false }
        @Override void addVerify(VerifyBean verifyBean) { vs << verifyBean }
        @Override void remoreVerify(VerifyBean verifyBean) { vs.remove(verifyBean) }
        @Override void removeAllVerify() { vs.clear() }
        @Override void saveResult() {}
        @Override void run() {
            synchronized (client.msgs) {
                client.msgs.each { x ->
                    vs.each { v ->
                        def s = x.substring(1, x.length() - 1)
                        v.setValue(s)
                        v.verify()
                    }
                }
            }
        }
    }
}

The console output demonstrates the sequence of login, socket connection, registration, room join/leave, and the verification results for each VerifyBean instance, confirming successful validation of both the response command and the teacher ID.
