Best Practices for your Jmeter Tests

Guidelines to overcome limitations of JMeter in distributed environment:

1. Limit the Number of Threads
2. Using a proxy server
3. Using variables
4. Reduce resource requirement
5. Check the JMeter logs
6. Erase the local path from CSV Data Set Config
7. Follow file naming convention

JMeter has some limitations especially when it is run in a distributed environment. To use JMeter efficiently for testing, you should use following guidelines:

Limit the Number of Threads

The maximum number of threads you can effectively run with JMeter is 300. This limit is because of hardware's capabilities. If JMeter is made to run with more number of threads, the accuracy of timing information will decrease.

Using a proxy server

The Proxy server helps you to abstract out certain common elements from the recorded samples. Moreover, it is useful features to record your testing.

Using variables

Some test plans need to use different values for different users/threads. For example, you might want to test   a sequence that requires a unique login for each user. This is easy to achieve using variables.

Reduce resource requirement

The GUI mode consumes a lot of computer memory under heavy load. It causes performance issues.

There're some tips to reduce resource requirement:

• Use non-GUI mode
• Disable the "View Result Tree" listener during the Load test. Because it consumes more memory and causes JMeter running to run out of memory.
• Disable all JMeter graphs results
• Use CSV test result format.
• Only save the needed test result. JMeter could take a long time to save very detailed test results.

Check the JMeter logs

Any errors in the test plan or test execution will be recorded in the log files. Monitoring the log file help you   to find the error early

Erase the local path from CSV Data Set Config

If you are using an existing CSV data file that you created on your local computer, you should delete the existing local path (Current path of CSV file). If you don't delete the local path, JMeter cannot find the CSV data file on your local PC.

Follow file naming convention

Don't save test plan under complex file name, use only alphanumeric characters.
