Using Docker Compose 🐳

A sample user authentication app to test Keploy integration capabilities using Gin and Redis.

Clone a sample user authentication app 🧪

git clone https://github.com/keploy/samples-go.git && cd samples-go/gin-redis
go mod download

We will be using Docker compose to run the application as well as Redis on Docker container.

Lights, Camera, Record! 🎥

Setup the Redis Database 📦

Start the Redis instance using the docker-compose file-

docker compose up redis

Now, we will create the docker image of our application:-

docker build -t gin-app:1.0 .

Capture the test-cases-

keploy record -c "docker run -p 3001:3001 --network <networkName> --name ginRedisApp gin-app:1.0"

🔥Make some API calls. Postman, Hoppscotch or even curl - take your pick!

Let's make URLs short and sweet:

1. Request OTP

curl --location 'localhost:3001/api/getVerificationCode?email=something@gmail.com&username=shivamsourav'

This returns the OTP response:

{
  "status": "true",
  "message": "OTP Generated successfully",
  "otp": "5486"
}

2. Verify OTP

curl --location 'localhost:3001/api/verifyCode' \
--header 'Content-Type: application/json' \
--data-raw '{
    "otp":2121,
    "email":"something@gmail.com"
}'

This returns the OTP verification response:

{
  "status": "true",
  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ2YWx1ZSI6ImdtYWlsLmNvbSIsImV4cCI6MTY5ODc1ODIyNn0.eVrNACUY93g-5tu8fxb2BEOs1wn2iCe8wVpUYU6OLSE",
  "username": "shivamsourav",
  "message": "OTP authenticated successfully"
}

🎉 Woohoo! With a simple API call, you've crafted a test case with a mock! Dive into the Keploy directory and feast your eyes on the newly minted test-1.yml and mocks.yml

Run Tests

Time to put things to the test 🧪

keploy test -c "docker run -p 3001:3001 --rm --network <networkName> --name ginRedisApp gin-app:1.0" --delay 10

The --delay flag? Oh, that's just giving your app a little breather (in seconds) before the test cases come knocking.

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. 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.😊🚀

Happy coding! ✨👩‍💻👨‍💻✨

Running App Locally on Linux/WSL 🐧

A sample user authentication app to test Keploy integration capabilities using Gin and Redis.

Clone a sample user authentication app 🧪

git clone https://github.com/keploy/samples-go.git && cd samples-go/gin-redis
go mod download

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

📼 Roll the Tape - Recording Time!

Start the Redis database using docker-compose:

docker compose up redis

Create a binary of our application:

go build -o gin-redis

Ready, set, record! Here's how:

sudo -E PATH=$PATH keploy record -c "./gin-redis"

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. Request OTP

curl --location 'localhost:3001/api/getVerificationCode?email=something@gmail.com&username=shivamsourav'

This will return the OTP response:

{
  "status": "true",
  "message": "OTP Generated successfully",
  "otp": "5486"
}

2. Verify OTP

curl --location 'localhost:3001/api/verifyCode' \
--header 'Content-Type: application/json' \
--data-raw '{
    "otp":2121,
    "email":"something@gmail.com"
}'

This will return the OTP verification response:

{
  "status": "true",
  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ2YWx1ZSI6ImdtYWlsLmNvbSIsImV4cCI6MTY5ODc1ODIyNn0.eVrNACUY93g-5tu8fxb2BEOs1wn2iCe8wVpUYU6OLSE",
  "username": "shivamsourav",
  "message": "OTP authenticated successfully"
}

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-1.yml and mocks.yml.
