Gatling Load Testing

Gatling is an open-source load testing tool for web applications. As part of this project you will run Gatling (gatling-runner) against a Spring Boot application exposing a Rest endpoint (spring-app).

The Gatling runner uses the official Gatling bundle and provides a custom scenario defined into the SampleService.scala file.

You will be able to run the application and the Gatling simulation using docker-compose, no other tools are required.

How to use

Download the project:

git clone https://github.com/francescofavatella/gatling-load-testing.git
cd gatling-load-testing

Start the Spring application and the Gatling simulation using Docker compose:

docker-compose up

For each simulation Gatling provides us HTML report of the test that we performed. Results will be saved into the ./gatling-runner/results.

The SampleService.scala file (./gatling-runner/simulations/sample/SampleService.scala) contains the scenario setup.

Spring-app

The Spring Boot application was generated using the Spring Initializer adding the following dependencies:

• spring-web
• lombok (not required)
• prometheus (not required)

Start only the Spring Boot app using Docker (optional)

docker build -t spring-app .
docker images

docker run -d -it -p 8080:8080 --name=local.spring-app spring-app
docker logs local.spring-app -f

curl http://localhost:8080
Hello Docker World%

docker stop local.spring-app

docker ps -a
docker rm CONTAINER_ID

docker rmi spring-app
