Sample Rest API with Spring-Boot and MongoDB

Introduction

🪄 Dive into the world of REST API and see how seamlessly Keploy integrates with Spring-Boot and MongoDB Buckle up, it's gonna be a fun ride! 🎢

Don’t have Keploy installed yet?

Before running this sample, make sure Keploy is installed on your system.

👉 Go to Installation Guide

Pre-Requisite 🛠️

• Install JDK and add JAVA_HOME in environment variable.
• Install Maven
• Install Docker

Get Started! 🎬

Set up the Mongo database

Create a docker network -

docker network create backend

Start the MongoDB instance -

docker run -p 27017:27017 --name spring-boot-mongo --network backend mongo

Clone the sample REST API CRUD app 🧪

git clone https://github.com/keploy/samples-java.git && cd samples-java/spring-boot-mongo
mvn wrapper:wrapper
./mvnw clean install

Note: For Windows, use mvnw.cmd clean install

Run Application

We'll be running our sample application right on Linux, but just to make things a tad more thrilling, we'll have the database (mongoDB) chill on Docker. Ready? Let's get the party started!🎉

📼 Roll the Tape - Recording Time!

Ready, set, record! Here's how:

keploy record -c "./mvnw spring-boot:run"

Alright, magician! With the app alive and kicking, let's weave some test cases. The spell? Making some API calls! Postman, Hoppscotch, or the classic curl - pick your wand.

Generate testcases

To generate testcases we just need to make some API calls.

1. Make a POST request

curl --location 'http://localhost:8080/potions' \
--header 'Content-Type: application/json' \
--data '    {
      "name": "Strength Potion v2",
      "description": "Enhances the drinker'\''s physical strength temporarily.",
      "bottle": 3,
      "quantity": 150
  }'

2. Make a GET request

curl --location --request GET 'http://localhost:8080/potions'

Take a note of the id and replace the UUID_OF_POTION with the id in the upcoming API requests!

3. Make a PUT request

  curl --location --request PUT 'http://localhost:8080/potions/UUID_OF_POTION' \
  --header 'Content-Type: application/json' \
  --data '    {
        "name": "Strength Potion",
        "description": "Enhances the drinker'\''s physical strength temporarily.",
        "bottle": 5,
        "quantity": 200
    }'

4. Make a GET request

curl --location --request GET 'http://localhost:8080/potions/UUID_OF_POTION'

5. Make a DELETE request

curl --location --request DELETE 'http://localhost:8080/potions/UUID_OF_POTION'

Give yourself a pat on the back! With that simple spell, you've conjured up a test case with a mock! Explore the Keploy directory and you'll discover your handiwork in test-x.yml and mocks.yml.

Want to see if everything works as expected?

Run Tests 🏁

Ready to put your spells to the test?

keploy test -c "./mvnw spring-boot:run" --delay 15

This will run the tests and generate the report in the Keploy/reports directory in the CWD.

Final thoughts? Dive deeper! Try different API calls, tweak the DB response in the mocks.yml, or fiddle with the request or response in test-x.yml. We provided you with some data in potions.json. Run the tests again and see the magic unfold! ✨👩‍💻👨‍💻✨

Wrapping it up 🎉

Congrats on the journey so far! You've seen Keploy's power, flexed your coding muscles, and had a bit of fun too! Now, go out there and keep exploring, innovating, and creating! Remember, with the right tools and a sprinkle of fun, anything's possible. 😊🚀
