Sample SMS Sending App​

Using Docker Compose 🐳​

🪄 Dive into the world of SMS Sending Apps and see how seamlessly Keploy can be integrated with FastAPI and Twilio . 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

Get Started! 🎬​

Setup the Twilio Account 💬​

You can get your Twilio credentials by signing in to Twilio Console. Once you get the Twilio Account SID, Auth Token, and Phone Number, modify the .env file with your credentials.

Clone the Sample App 🧪​

git clone https://github.com/keploy/samples-python.git && cd samples-python/fastapi-twilio

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

Lights, Camera, Record! 🎥​

Create the docker image of the app:

docker build -t fastapi-twilio:1.0 .

Capture the test-cases-

keploy record -c "docker run -p 8000:8000 --name fastapi-twilio fastapi-twilio:1.0"

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

Let's make URLs short and sweet:

Generate testcases​

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

Make the POST requests

  1. Replace the place holder below i.e. YOUR_REGISTERED_PERSONAL_PHONE_NUMBER with your registered personal phone number that you linked with Twilio.
curl --location 'http://127.0.0.1:8000/send-sms/' \
--header 'Content-Type: application/json' \
--data '{
    "Body": "Test, testtt, testttttttssss :)",
    "To": "YOUR_REGISTERED_PERSONAL_PHONE_NUMBER",
}'
  1. Replace the place holder below i.e. SOME_WRONG_PHONE_NUMBER with any wrong phone number and make the request.
curl --location 'http://127.0.0.1:8000/send-sms/' \
--header 'Content-Type: application/json' \
--data '{
    "Body": "Test, testtt, testttttttssss :)",
    "To": "SOME_WRONG_PHONE_NUMBER",
}'

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.

Want to see if everything works as expected?

Run Tests​

Time to put things to the test 🧪

keploy test -c "docker run -p 8000:8000 --name fastapi-twilio fastapi-twilio: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 Twilio 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! ✨👩‍💻👨‍💻✨

Keep an eye out for the -c flag! It's the command charm to run the app.

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.
