How to write to a file with JMeter
Creating files from your script during runtime and finding it after your flood
There are several reasons why you might need the ability to write to a file during runtime. For example, maybe you'd like to save your results as a .jtl file. Luckily, this is very easy to do with Flood. All you have to do is modify your script to create the .jtl file by adding a listener such as the Simple Data Writer and using the absolute path /data/flood/results/ like this:
This will ensure that the .jtl is created after your test is executed.
If you want to write something other than results to a file in JMeter, you can use BeanShell to add code. You can do this by adding a BeanShell Sampler, BeanShell Preprocessor or BeanShell Postprocessor to your test plan and using something like this to create the file and populate it:
FileWriter f = new FileWriter("PATH_HERE/accountscreated.csv",true);
BufferedWriter out = new BufferedWriter(f);
out.write(vars.get("accountNumber") + "\n");
