#Apache jmeter load testing install#

Install Petstore application on a local Tomcat server.The following example parameterizes the pet category from the Java Pet Store. User_1) is defined, the value will be used for all threads.

Within Thread Groups, the User Parameters Pre-Processor can be used to set different parameters for each simulated user. How do I parameterize my JMeter test cases?Īnswer: Parameters can be set at both the Test Plan and Thread Group levels.Īt the Test Plan level, parameters can be used as constants to minimize changes throughout the test plan when a server or port changes, for example. Long answer: try using v1.9RC1, the code in HTTPSampler seems to take into account the result code for the redirect instead of the redirect result code. Why do HTTP 3xx redirects appear as errors ? Is there a way to make them appear as HTTP 200 OKĪnswer: Quick answer: They appear as an error because 302 != 200, at least in v 1.8.1.

Someone needs to write a good EJB Sampler implementation for JMeter (hint, hint).

How can I do stress testing of EJBs?Īnswer: You can use the UserManual Reference/JavaSampler classes to write your own class that runs your EJB's, and then JMeter will take over the threading and reporting. I have permission from the author of this ant task to add it to JMeter's distribution, which I will do as soon as I have the time.

How to run JMeter test plan programatically, such as from an Ant script?Īnswer: Quick answer, go here. If there are several nodes running the JMeter test plan, it is a good idea to try and ensure that their clocks are synchronised, as this makes it easier to analyse the data later. (CVS files can just be appended to each other XML output files need a bit of editting to maintain well-formedness.) The output log files can be merged after the test run and used to create overall test statistics. Running JMeter in non-GUI (batch) mode is preferable, as this uses far fewer resources. Remove all unnecessary listeners before running stress tests. Note that if the GUI is running multiple remote servers, it can easily become a bottle-neck, especially if a lot of listeners are being used. Execute more test threads than your local machine is capable of handling.Eliminate the impact of slow network connections when you are not 'close' to the application server.While you are developing your scripts and for only moderate levels of user testing (assuming you are 'close' to the application server) you do not need to involve any JMeterEngine machines. A single machine running the JMeter GUI that you use to control the machines running the JMeterEngine.

The JMeter User Manual provides reasonable information about doing this. By 'reasonably close' I mean on the same Ethernet segment or at least with no low speed links between them. You want these machines to be reasonably close (network wise) to the application server.

One or more machines running jmeter-server (the JMeterEngine).

You shouldn't run anything on this machine that you wouldn't have running on it in your proposed or actual production environment (if you are running anything else, including JMeter, you will be adding load to the server and thus tainting your results). How to do remote testing the 'proper way'?Īnswer: Here are a few notes to help you on your way.
