Load distribution of transaction in JMeter

Question

During load testing can we achieve different transaction rate in same flow?

For example: I have a e-commerce web based application to do the load testing and I have to design the test in order to achieve TPH as below.

a. Transaction A: Login (100 transaction/hour) b. Transaction B: Search Product (500 transaction/hour) c. Transaction C: Payment (300 transaction/hour) d. Transaction D: Logout (100 transaction/hour)

Could you please help me with Jmeter element configuration also?

Answer 1

You can use this component from jmeter-plugins 3rd party project:

• https://jmeter-plugins.org/wiki/ThroughputShapingTimer/

It allows you to control throughput which. is what you're looking for here.

Answer 2

Your testing doesn't assume much load as 1000 requests per hour is less than 1 request each 3 seconds which is easily achievable either manually or using Selenium browser-based tests.

If for some reason you need to proceed with JMeter take a look at Constant Throughput Timer which can limit requests execution rate to the desired value.

Example configuration:

1. Add Constant Throughput Timer as a child of the Login sampler.
2. Add 1.66 to the "Target Throughput" input (100 requests per hour / 60 minutes in hour)
3. Switch "Calculate Throughput based on" dropdown to ie all active threads in current thread group so the throughput setting could be shared across all threads
