# Sample SMS Sending App

> The following sample app showcases how to use the FastAPI framework with Twilio's SMS Service and the Keploy Platform.

## 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! 🎢

## 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 🧪

```bash
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:

```bash
docker build -t fastapi-twilio:1.0 .
```

Capture the test-cases-

```shell
keploy record -c "docker run -p 8000:8000 --name fastapi-twilio --network keploy-network 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.

     ```bash
     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",
     }'
     ```

    2. Replace the place holder below i.e. `SOME_WRONG_PHONE_NUMBER` with any wrong phone number and make the request.

     ```bash
     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`.

```yaml

### Run Tests

Time to put things to the test 🧪

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

## Setup the Twilio Account 💬

You can get your Twilio credentials by signing in to Twilio Console.

```

### Lights, Camera, Record! 🎥

```bash
keploy record -c "uvicorn application.main:app --reload"
```

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.
