#SCRIPT ERRORS MAX RECORDER HOW TO#

Memory consuming listeners such as “View Results Tree” or any of the graphical reporting listeners can cause the console to freeze without providing any prior alert. The JMeter console running in GUI mode can consume a lot of CPU and memory. Use multiple instances of JMeter in case the large number of threads/users is required to be simulated.Always use relative path for csv file if used in the script.Do not forget to add timers as per your requirement.

Make sure how to use cookie manager and cache manager along with your requirement.

Try to run the script in non-GUI mode for simulating large concurrency.

Keep Result Tree disable when run for large number of users.

Always keep “Retrieve all embedded resources” checked to make it behave more like a browser.

Follow Naming convention for all elements.

Organize the samplers and other elements in most easy way.

(Lets say if you are recording with HTTP(S) Test Script Recorder from Non-Test Elements) Remove unnecessary requests from the plan.Below are some standards that we should follow while developing scripts: Develop the jmx files according to the project requirement. There are number of tutorials available over the internet which gives us step by step guide for developing scripts in JMeter. Best Practices for JMeter Script Preparation Once Performance Test Plan is prepared, next step is to develop scripts. It would be really easy to prepare a performance Test Plan once we get all answers to above questions. Is there any scalability requirement over the period of time?.What will be the Infrastructure set up and application architecture?.What will be the duration? How long will the load remain on the system?.What is the acceptable response time for the pages for performance testing?.List of pages/activities that would be used more often to prioritize for Performance testing?.How many concurrent users do we expect the application to support on an average during peak duration?.How many concurrent users do we expect the application to support on an average at any given point in time?.Listeners (unless SampleResult is null)īefore starting Performance Testing using JMeter, below are the common questions that one should clarify with the customer.

Assertions (unless SampleResult is null).

Post-Processors (unless SampleResult is null).

JMeter will execute the test plan elements in the following order: In order to check the performance of any web application, you need to first create a test plan consisting of the following elements:Īfter creating the test plan, you need to create the test scripts and run those scripts. JMeter is not a browser rather it’s purely a Java based application that works at the protocol level. You can simulate almost anything using JMeter scripting like log in, posting of forms, various browsers and so on but executing tests using JMeter is a totally different matter.Apache JMeter is an open source load testing tool used to perform load test on web applications (client/server). Apache JMeter is an awesome tool that provides excellent scripting capabilities.
