Student TinyService for Load Testing (RESTful)

Here is a medium article on how to use this repository to design and run basic load tests using Apache JMeter and Taurus frameworks.

This is a Spring Boot 2.1.6 tiny app that includes webapp, actuator, spring-data-jpa starts and exposes four (4) endpoints as listed below

  1. List Students localhost:8080/students/list - GET
  2. Get Student by Id localhost:8080/students/{sid} - GET
  3. Delete Student by Id localhost:8080/students/{sid} - DELETE
  4. Create Student localhost:8080/students - POST

This TinyService is backed by an in-memory database called h2 that is pretty straight-forward to setup. All that is needed to do is

  • Drop a data.sql file in the /src/main/resources and upon start up those SQLs will be executed
  • Add a few configuration to the application.properties in order to enable the h2 database as well as to enable the h2-console that is accessible depending on server url localhost:8080/h2-console (when the application is running).

Note: The in-memory version of h2 means the content of the database will only live during the life-cycle of the application.

Upon start-up of the application we have PopulateDatabase class that basically uses Spring Data repository to create 20K Student object and Bulk Save it in the db. So once your application is started, you have nearly 20K records. You can increase/decrease this as you wish.

Note: When navigating to h2-console don't forget to update the JDBC url to point to the same that is in src/main/resources/application.properties

How to Get Started?

Glad you asked! All you have to do is ensure that you have maven and do the following steps

  • Clone the repo locally
  • Run mvn spring-boot:run command and the TinyService application will run in the command line

How to Interact with the Endpoints?

Hit the endpoints above curl localhost:8080/students/42 or curl localhost:8080/students/list to interact with the endpoints.

Congratulations! You are all done! Your tiny service is up and running. It exposes create, read, list, and delete endpoints that I used to do a load test demo.

Note: This App was used for a Load Test Demo hence, why the Service layer and Tests are skipped.
