jmeter example

I. Description of the toolApache JMeter is a 100% Java desktop application designed to load the features of the tested software and measure the performance of the software being tested. The design JMeter was originally designed to test Web applications and later expanded other functions. JMeter can perform performance tests on static and dynamic resources (Servle

Purpose: To test the Java programDirectoryFirst, the core stepsSecond, examplesThird, JMeter Java Sampler IntroductionIv. bring your own Java Request SamplerFirst, the core steps1. Create a Java project;2. Add the jar file in the JMeter Lib directory to the build Path of this project;3. Create a class and implement the Javasamplerclient interface or inherit abstractjavasamplerclient, and rewrite it;Public A

ObjectiveJMeter is an open source tool for performance testing, stress testing, and is being tested by a large number of testers to test product performance, load, and more. JMeter In addition to the powerful presets of various plugins, various visual charting tools, there are some inherent flaws, such as: We often can only analyze the performance of the same deployment in the report, it is inconvenient to make a vertical comparison, for

JMeter Execution Order rules: Configuring components Front-facing processor Timer Sampling device Post processor (unless server response is empty) Assertion Listener The timer, assertion, pre/post processor is executed only when the sampler is present in the scope, and the logic controller and sampler are executed in the order in which they appear in the test tree. Other test elements are executed according to their own scope

first , the question:When I was doing performance testing, I used jmeter to make 100 concurrent, with 100TPS pressure to test 10 minutes, but the pressure has been fluctuating, and fluctuations in the JMeter very card, such as:Periodic TPS fluctuationsVarious speculations:So began to look for various reasons for the environment, at first thought is JMeter connect

1. Install the JDK and configure the environment variablesTake 1.8 as an example:(1) installation of jdk1.8;(2) In the system variable click New, variable name fill java_home, variable value fill JDK installation path "C:\Program files\java\jdk1.8.0_40", environment variable position 1Figure 1(3) In the system variable, click the new variable name to fill in the Classpath, the value of the variable filled ".; %java_home%\lib;%java_home%\lib\tools.jar

processor is often used to process the response data.6. Assertion--to determine if the result of the request response is as expected by the user. It can be used to check the validity of the test, isolate the problem domain, and perform the stress test if the function is correct.7, the listener-responsible for collecting test results, and in a variety of ways to display.Simple example:1) First add a thread group and set the thread concurrency amount:w

: Control Thread Group Set the number of threads Setting the ramp-up cycle Set the number of cycles to test execution Each thread executes the test plan completely and independently without affecting other threads. Multithreading can be used to simulate concurrent connections to your server programs.Ramp-up period tells JMeter how long it takes to "ramp-up" to load all the threads, if 30 threads are used, and ramp-up period i

Using Nmon to monitor resources5.Jenkins Parametric transferIssue: Jmetermavenplugin+jenkins Integration performs Java interface class performance testing,1. First customize the Java interface test class, debugging through the export of a separate test class jar package, and copy the jar package to JMeter. /lib/ext directory. (Note copy other dependent jar packages at

. Implementation: Here we record the default fill in the Java protocol is filled with: HTTP method is: GET Content encoding: Encoding can not fill in the path: that is, the path of the page, the following redirection and other options can be checked as required,　　Here we keep recording without modification.　　Parameters parameter: That is, the parameters sent along with the path and the proxy server under the file can be ignored, fill in as required.　　C, parameterized as follows, we parameterize

configured to run how many threads, each thread loop how many times, all the number of threads total boot time (ramp-up period) and so on.2. ControllerThis includes logical controllers and sampler, which are used for some logical control, such as rotations, conditions, loops, and so on. Sampler is really a "work" of "sampler", such as "HTTP request", is to carry out an HTTP request.3, ListenerListener to listen to the request process can be simply understood to obtain the results of the Dongdon

begins, JMeter will wait as necessary until the start time is reached. 　　 At the end of each loop, JMeter checks to see if the end time has been reached and, if so, stops running, or the test continues until the iteration limit is reached. 3, the controller (controllers) JMeter has two kinds of controllers: Sampler and logic controller. 　　The processing of these

Before using JMeter to do performance testing, basically use their own laptop.The following analysis is carried out considering the network transmission and utilization of system resources:1 on the notebook, start-cmd "ping Server" to get the transfer time. "Ping the Server" on a Linux machine to get the transmission time, the two time is similar, think does not affect the test result2 generally I used to test the Linux test machine and notebook compu

In general, the programming tools IDE provides the appropriate debugging modules for developers to use in order to locate the problem more quickly. So what debugging tools does JMeter provide for us to use while jmeter writing test scripts?JMeter commonly used debuggers have the following five kinds:1. View tree: See the result trees.

The JMeter test plan has an option called the "function test mode", which , if selected, causes the JMeter to record every sampled data returned from the server. If you select a file in the test listener, the data will be written to the file. This is useful if you try a smaller test to ensure that the JMeter is configured correctly and that your server is returni
