This example demonstrates how to integrate goverage into a Go application.

• Go 1.20 or higher

1. Build the application:

   ./build.sh

2. Run the application:

   export GOCOVERDIR=/tmp/coverage-example
   ./example-app

3. Test the endpoints:

   # Health check
   curl http://localhost:8080/api/health
   
   # Calculator
   curl "http://localhost:8080/api/calculate?a=5&b=3"

4. Get coverage data:

   curl -X POST http://localhost:7777/v1/cover/profile

Run the complete test workflow:

./test.sh

This script will:

• Build the app with coverage
• Start the server
• Exercise the endpoints
• Collect coverage data
• Display the results

The example application includes several code paths:

• Basic HTTP handlers
• Conditional logic in the calculator
• Different calculation scenarios (positive, zero, negative numbers)

By testing different endpoints and parameters, you can see how coverage changes in real-time.

Without coverage:

go build -o example-app .
# Coverage server is NOT included (due to build tags)

With coverage:

go build -cover -covermode=atomic -tags=goverage -o example-app .
# Coverage server IS included and starts automatically
