Load Testing Create and Delete Resource APIs with a Java Automation Script

Simple Function Description

The first API creates a resource using parameters such as knowledge point ID (kid), class ID, class type (0‑admin class, 3‑teaching class), course type, subject ID, minicourse ID, activity name, page index, and page size. A successful response returns a JSON object containing the newly generated activity_id.

params.put("kid", kid);
params.put("class_id", class_id);
params.put("class_type", 3); // 0‑admin class, 3‑teaching class
params.put("course_type", course_type);
params.put("subject_id", subject_id);
params.put("minicourse_id", minicourse_id);
params.put("activity_name", activity_name);
params.put("page_index", 1);
params.put("page_size", 10);

Response example:

{
  "data": {
    "activity_id": 674
  },
  "meta": {
    "emsg": "",
    "ecode": 0
  }
}

Delete Interface

The second API deletes the resource identified by the activity_id returned from the first call.

JSONObject params = getParams();
params.put("activity_id", activity_id);

Response format is similar, with a JSON object containing meta information.

A special case: for the same minicourse_id, the creation request always returns the same ID, and the delete operation is actually an UPDATE in the database. To avoid interference between concurrent threads, the test binds each thread to a specific user’s test data.

Method Encapsulation

Two helper methods— createPre and delPre —are wrapped with default parameter values to simplify calls.

/** Create a lesson preparation */
public JSONObject createPre(int kid = 68, int class_id = 50167, int course_type = 4,
                           int subject_id = 6, int minicourse_id = 2109354,
                           String activity_name = "FunTester") {
    String url = MirroApi.CREATE_PRE;
    JSONObject params = getParams();
    params.put("kid", kid);
    params.put("class_id", class_id);
    params.put("class_type", 3);
    params.put("course_type", course_type);
    params.put("subject_id", subject_id);
    params.put("minicourse_id", minicourse_id);
    params.put("activity_name", activity_name);
    params.put("page_index", 1);
    params.put("page_size", 10);
    JSONObject response = getPostResponse(url, params);
    output(response);
}

/** Delete a lesson preparation */
public JSONObject delPre(int activity_id = 343) {
    String url = MirroApi.DEL_PRE;
    JSONObject params = getParams();
    params.put("activity_id", activity_id);
    JSONObject response = getPostResponse(url, params);
    output(response);
}

Load Test Script

The following Java script launches 200 concurrent threads, each creating a resource and then deleting it, while recording the activity_id for subsequent deletion.

package com.okayqa.composer;

import com.fun.base.constaint.ThreadLimitTimesCount;
import com.fun.frame.excute.Concurrent;
import com.okayqa.composer.base.OkayBase;
import com.okayqa.composer.function.Mirro;

class COMT extends OkayBase {

    public static void main(String[] args) {
        def res = [];
        200.times {
            def base1 = getBase(it);
            def mirro1 = new Mirro(base1);
            res << new TT(mirro1, 50);
        }
        new Concurrent(res, "创建备课删除备课").start();
        allOver();
    }

    static class TT extends ThreadLimitTimesCount {
        Mirro m;
        int aid = 0;

        public TT(Mirro mirro, int times) {
            super();
            this.m = mirro;
            this.times = times;
        }

        @Override
        protected void doing() throws Exception {
            def pre = m.createPre();
            if (aid == 0) {
                aid = pre.getJSONObject("data").getIntValue("activity_id");
            }
            m.delPre(aid);
        }
    }
}
