🪄 Dive into the world of realtime subscriptions and see how seamlessly Keploy integrates with SSE and MongoDB Buckle up, it's gonna be a fun ride! 🎢

import InstallationGuide from '../concepts/installation.md'

Installation 📥

Ways you can run this sample application.

• Using Docker container for MongoDB and running application locally

Installation Setup

Server

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

Start MongoDB Instance

Using the docker-compose file we will start our mongodb instance:-

# Start Postgres
docker-compose up mongo

Build Application Binary

Now, we will create the binary of our application:-

go build -cover

Once we have our applicaiton binary ready, we will start the application with keploy to start capturing the testcases.

Capture the test cases

sudo -E keploy record "./sse-mongo"

Start the UI

We will capture our test from the UI written in Svelte.js

cd svelte-app && npm install && npm run dev

Now let's click on GetTime button to trigger the event. We would notice that keploy will capture those calls : -

Run the Testcases

Now let's run the test mode :-

keploy test -c "./sse-mongo" --delay 10 --goCoverage

Output should look like : -

So no need to setup fake database/apis like Postgres or write mocks for them. Keploy automatically mocks them and, The application thinks it's talking to MongoDb 😄. And with just few clicks we were able to get 42% code coverage of our go backend application.
