Api load testing with certain scenarios

Question

Hei. I've done some api testing with java using restassured framework, but this doesn't seem to have a good solution for load testing. I would need a recommendation for a tool that could help me with it.

The problem is that the load testing will be done between "users". I have 2 sets of users and I want to create tests where they communicate with each other etc.

Example: 2 sets of users. Each set has 100 users.

Case 1:

• User1 from set 1 sends a message to User2 from set 2.
• User2 from set 2 responds to User1 from set 1.
• User2 will do smth etc.

Basically I need to write load tests where I test the interaction between multiple users. I want to see if the servers can handle alot of interactions going on at the same time.

Restassured sadly doesn't support it and I need and alternative solution which allows me to handle these cases.

Answer 1

Any load testing tool which supports HTTP protocol and parameterization will suit, here is a shortlist:

• SoapUI is kind of web service functional testing standard. It has some limited load testing capabilities as well
• Apache JMeter is kind of load testing standard in free and open source software world, it is multiprotocol modular solution which supports web service testing as well. Using JMeter you will be able to create more load and get extended reporting.

Answer 2

You can record Case 1: scenario using blazemeter chrome extension that generates .jmx file and imports it into the Jmeter and set your threads to 100 users.
