How to Duplicate file using JMeter

I am trying to duplicate a file using JMeter,

The scenario:

  1. Loading a JSON file. For example, {"name":"John","age":"$age_place"}
  2. Modify one property - age_place from 1 to 20
  3. Save each modified iteration into a separate file

I have tried to do that with Simple Data Writer but it didn't work.

If you need to generate 20 files with different age you can do it using any of JSR223 Test Elements. Example Groovy code would look like:

def json = new groovy.json.JsonSlurper().parseText("{\"name\":\"John\",\"age\":\"\"}")
def builder = new groovy.json.JsonBuilder(json)
1.upto(20, {
    builder.content.age= "${it}"
    def writer = new File('file' + "${it}" + ".json").newWriter()
    writer << builder.toPrettyString()
    writer.close()
})

Once you execute your test it will create the following files in the "bin" folder of your JMeter installation:

  • file1.json - with the age of 1
  • file2.json - with the age of 2
  • ...
  • file20.json - with the age of 20

You have JSR223 Elements as Sampler or Pre processor which you can add powerful script,

The easiest is to replace age_place with your value, for example if saved in variable age_place:

f = new FileOutputStream("c:\\temp\\template.json", false);
p = new PrintStream(f); 
this.interpreter.setOut(p); 
print("{\"name\":\"John\",\"age\":\"age_place\"}".replaceAll("age_place", vars.get("age_place")));
f.close();
