Stress test WebService with JMeter

In real projects, we use JMeter Yes WebService Stress tests were carried out ,ApacheJMeter yes Apache Organization development based on Java Pressure testing tools for . For stress testing software .

One 、JMeter The role of

1. Can be right HTTP and FTP The server Perform pressure and performance tests , You can do the same for any database （ adopt JDBC）.

2. Complete portability and 100% pure java.

3. Completely Swing And lightweight component support （ precompiled JAR Use javax.swing.*) package .

4. Full multithreading The framework allows concurrent sampling and Sampling different functions simultaneously through separate thread groups .

5. Elaborate GUI The design allows fast operation and more accurate timing .

6. Caching and offline analysis / Replay test results .

Two 、 About Jmeter The configuration of relevant environment variables of is similar to Java Configuration of , Refer to online materials

3、 ... and 、Jmeter in the light of Http Agreed webservice Test case .

1: First, create a new thread group in the test plan

among , The number of threads and the number of cycles in the thread attribute represent the actual number of runs when a test is executed , That is, access webservice The number of times .

2: Create a new thread group HTTP request ( About the configuration of related addresses and some parameters of the access interface service ) and HTTP Information manager ( send out webservice Public request header during service ), Aggregation report ( Test report ).

Four 、 After configuring everything , Click start to execute the test

=============we test webservice by http head start=========== name=clark =============we test webservice by http head end===========

remarks ==================================== The following is about webservice The configuration of services is integrated into spring in

}

If you need to check after executing the test Jmeter The returned results in , We need to create a new view result tree under the thread group ( Right click thread group > add to > Monitor > Look at the fruit tree ), In the response data column, you can see the result returned by the response

Be careful : stay Jmeter send out JSON When testing the format of string , We deliver JSON Parameter name cannot be given when parameter , Instead, you should give values directly . Otherwise, when it is transferred to the background, it will contain a series of non string styles -- Cause it to be garbled . It cannot be correctly resolved to the object we need . {"name":"zhangsan","description":"its"} You can , No need jsonStr = {"name":"zhangsan","description":"its"} It came from json We only need to resolve the parameter to the object corresponding to our background . /**     * take JSON character string Convert to object     *     * @author weiyuanhua     * @date 2010-11-18 Afternoon 02:52:13     * @param jsonStr     *            JSON character string     * @param beanClass     *            Generic object     * @param field     *            Properties that need to be ignored in the object     * @return     */     public static Object jsonToObject(String jsonStr, Class<?> beanClass,String... field) {         JsonConfig jsonConfig = getJSONConfig(field);         JSONObject jsonObject = JSONObject.fromObject(jsonStr, jsonConfig);         return JSONObject.toBean(jsonObject, beanClass);     }

private static JsonConfig getJSONConfig(String... field) {         JsonConfig jsonConfig = new JsonConfig();         if (field != null) {             jsonConfig = new JsonConfig();             String[] exclu = new String[field.length];             for (int i = 0; i < field.length; i++) {                 exclu[i] = field[i];             }             jsonConfig.setExcludes(exclu);         }         return jsonConfig;     }
