Go to quickstart section for a fast start.

Used gin-gonic framework as core of the API, gorm as ORM with postgres as DB and SQLite as memory database for integration tests. API is secured using JWT and tests uses testify package.

Tests mainly cover “happy” path but good coverage was achieved. There are integration and unit tests, mocking techniques were used to isolate tests, service and repository layers and use of structs and interfaces were used to try to achieve a clean architecture. To run all tests: docker-compose exec me_wallet_service go test ./... You could run them locally as well.

Docker compose file is supplied with air for hot reload and a postgres database (no volumes for reboot persistence). Build and server with air (hot reload) should be ready to use with docker-compose.

Godotenv package is installed, and for security reasons a ACCESS_SECRET could be used. DB credentials are set by default on server creation to work with docker however the .env file could be used to provide something more specific.

Running docker-compose up should be enough to have everything setup.

On /swagger/index.html is the API documentation and playground, everything should be usable but consider the target user id for the transfer. The API needs an access token that is provided by the login method, on the swagger ui, just execute the example after running the seed.

Run seed to create test users: docker-compose exec me_wallet_service go run setup/seed.go

On src directory run swag init -g utils/server.go --output ../docs --parseDependency to generate swagger/open API v2 specs


docker-compose up
docker-compose exec me_wallet_service go run setup/seed.go
swag init -g utils/server.go --output ../docs --parseDependency
