This article describes the JMeter distributed run scripts to better achieve pre-set performance testing (concurrency) scenarios. At the same time, the JMeter command line (non-GUI) mode is also mentioned in the first section of the previous article, so this article continues with the previous article for a detailed explanation of JMeter's command-line mode.First, the application scenario1.

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 ".

You can also enter: Java-version View the Java version to see if the configuration was successful. After the OK,JDK installation is successful, you can install JMeter in the next step.3, installation JMeterUnzip the Apache-jmet

At this point, go to the Run->remote Start menu, You can see that the controller is also running as a remote machine. FAQ: 1, to determine on the controller machine installed JDK version and jmeter consistent 2, agent machine startup Jmeter_serve

You will see the address of the two agents we just added, select to run, if you want to start all agents at the same time, select Remote all start. 5, to be distributed test agent machine need to add environment variables, that is, add user variable Jmeter_home=d:
Common methods used for parameterization:
Adding configuration symbols: User-defined variables
Using the function Helper
Adding configuration components: CSV Data Set Config
Add Front Processor: BeanShell preprocessor
Adding configuration symbols: User-defined variablesUse in Request:Replace the original parameter value with ${userid} where it needs to be parameterizedUsing the function HelperExample:Generates a 5-bit charact

JmeterIntroduction: An excellent open-source performance testing tool.
Advantages: When you use it, you will find its many advantages. Of course, its shortcomings will also be shown.
Principles of Performance Tools:
The jmeter tool and other performance tools are exactly the same in principle. The tool consists of four parts:
(1) load generator: used to generate loads. It is usually used to simulate user behavior in multi-thread or multi
JMeter distributed operationJmeter is a Java application that consumes a large amount of CPU and memory, so when you need to emulate thousands of concurrent users, it is a bit of a problem to emulate all concurrent users with a single machine, or even cause a Java memory overflow error. In order for the JMeter tool to provide greater load capacity, JMeter has a m

The minimum test will include a test plan, a thread group, and one or more samplers. 1.
