![]() ![]() The -o "path_to_report_folder" switch tells JMeter where to generated the report (dashboard).The -e switch tells JMeter to generate a test report (dashboard) once the test has completed. The -j "path_to_log" switch says where to store the JMeter run log (e.g.The -l "path_to_jtl" switch tells JMeter where to log samples, this is the results file and the most important artifact of the test run.The -t "path_to_jmx" switch tells JMeter where on the file system to find the jmx file.The -n switch runs JMeter in commad-line mode.e -o "%projectdir%\reports\%testname%_%runname%" ^ j "%projectdir%\logs\debug_%testname%_%runname%.log" ^ l "%projectdir%\results\results_%testname%_%runname%.jtl" ^ %jmeterbin%\jmeter -n -f -t "%projectdir%\%testname%.jmx" ^ Thanks to the utilization of the variables mentioned above, the execution of JMeter with a passed in Test Plan as a command-line switch can easily be reviewed in just a few lines: This can help keep track of different runs of the same test. ![]() For multiple reasons, a typical load test can be run several times, with each having a slightly different option enabled within the Test Plan. set projectdir=C:\JMeter Tests\sampleworldcities3įor some extendibility, a variable is created for the name of the jmx file separate from the project folder (without the jmx extension and even if they utilize the same name)įor more convenience, a variable is created that will be appended to each run.set jmeterbin=C:\apache-jmeter-5.4.1\binĪs it the (manually created) project folder where the jmx file (e.g.Setting the path to the JMeter bin folder is straightforward We want to tell the batch script where to find Apache JMeter and our Test Plan. set heap=-Xms4g -Xmx4g -XX:MaxMetaspaceSize=256m.Increasing the default memory can be easily with the following However, the test client capabilities can also be a bottleneck that limits the ability of accomplish the test goals. Note: Many load tests focus on the resource utilization of the server hardware. This is adequate for simple tests running on older machine hardware, but some tests require more complex logic or multiple data files and more memory might be needed to ensure the tests results are not impacted Memoryīy default, Apache JMeter (version 5.4.1) runs with a minimum and maximum of 1GB of memory. The following sections are the primary components our batch will utilize variables. While hard-coding values is technically fine, it can hinder readability if paths for certain items are very long. Using variables are handy ways to improve the maintenance of a script. ![]() This favors repeatability and maintenance. Since the command-line is utilized for running the Apache JMeter load test, it is advantageous to assemble the actions and environment prep into a batch script (e.g.
