JMeter launcher (jmeter.jar)

The JMeter launcher allows running .jmx tests on web sites.
It has been tested with JMeter v2.4.


Configuration

The jmeter.xml file allows pre-configuring the launcher with some default values:


Parameter Description
General
Java install path This must indicate the path to the java install.

Default value is: C:/Program Files/Java/jdk1.6.0_17
Test root path This must indicate where are located all the JMeter tests.
This is a root path. Each test in XStudio has a canonical path that will be appended to this path.
This path MUST not include an ending slash.

Default value is: C:/test_repository/tests/jmeter
JMeter
JMeter install directory This must indicate where JMeter has been installed.

Default value is: C:/jakarta-jmeter-2.4
Temporary folder This must indicate the path of a folder where we are going to store temporary data.

Default value is: C:/WINDOWS/Temp


These values can be changed while creating the campaign session from XStudio.


Requirements

The launcher will first take care about running the JMeter server. Do NOT run the server by yourself.
The tests must be named with the extension .jmx.


The test will be marked as passed or failed depending on the rc attributes measured in the .jtl file generated by JMeter.
By default, the test cases succeed except if at least one entry contains a rc value >= 300.


In some particular cases though, the test actually expects that an http error is returned. In this case, the logic can be refined by using an attribute called "JMeter list of additional HTTP status codes authorized". You can set set this attribute to some particular tests with different values. This attribute must contain all the HTTP status code (';' separated) that must be considered as authorized for the test.

For instance:

will specify that for this test, error codes 302, 303, 304 and 402 must be considered as correct.


Tutorial: Creating and executing JMeter tests

In this tutorial, we will learn to run some JMeter .jmx tests.


Prerequisites

Install JMeter in the folder C:\jakarta-jmeter-2.4
Create a file Test1.jmx with JMeter IDE and save it to the folder C:\test_repository\tests\jmeter\folder1.



Create a dedicated category for JMeter tests and create a test

  • create a category JMeter associated to the launcher jmeter.jar
  • under this category, create (somewhere in the tree) a test with name Test1 and with a canonical path set to folder1.



Creating a test campaign

  • create a campaign including only the test Test1
  • create a campaign session using a configuration having all the default values.



Run a campaign session

Run the campaign session


After the session's execution is completed, you can look at the results from XStudio:
  • the messages indicate the status of the test
  • you can also check that all the log files (including the JMX, the JTL and the log files) are attached
