JMeter: How to generate 2 random float numbers in particular range and use it further

Question

Scenario is: Generate 1 random float number in between 0.01 to 500 and pass it as var_1

Generate 1 more float number in range of 0.01 to 0.17 and save it as var_2

Now, whatever is the number picked up by JMeter as var_1, add var_2 to it ie: var_1+var_2 and pass it as var_3

Answer 1

I recall answering something similar here , however probably I missed the step of storing the values into JMeter Variables

In JMeter's Groovy you have vars shorthand which stands for JMeterVariables class instance so you can use it to write generated values and their sum into the required variables like:

import org.apache.commons.lang3.RandomUtils

def float1 = RandomUtils.nextFloat(0.01f, 500f)
def float2 = RandomUtils.nextFloat(0.01f, 0.17f)
def sum = float1 + float2

vars.put('var_1', float1 as String)
vars.put('var_2', float2 as String)
vars.put('var_3', sum as String)

You can verify generated variables along with their values using Debug Sampler and View Results Tree Listener combination:
