Random Variable Configuration

Random Variable

The Random Variable is used to generate random numeric strings.


A click on the blue variable name in the Usage section will copy it to the clipboard.

It is randomized on every virtual user iteration, making it a good choice for a random value that needs to be consistent for a whole loop/iteration.


If you need a value that changes every time you use, try instead with the ${__random(...)} function.

For each Random Variable, you can edit:

Property name Description
Name The variable name. To inject it, use the ${...} syntax.
Description The variable description text.
Minimum Value The Random Variable range lower bound.
Maximum Value The Random Variable range upper bound.
Output Format The output format of the generated value. Leave blank for a simple number output. It uses the java.text.DecimalFormat. For example 000 generates numbers with at least 3 digits, and USER_000 generates output of the form USER_nnn.
