You need Docker and docker-compose installed.
Everything is running in Docker container, so you don't need golang either any other lib.
Just run
make up
It will build Docker image and run monolith and microservices version.
Monolith: http://localhost:8090/
Orders microservice: http://localhost:8070/
Shop microservice: http://localhost:8071/
Payments microservice: no public API (you can export ports in docker-compose.yml if you need)
For available methods, please check interfaces layer in source code and tests tests/acceptance_test.go.
First of all you must run services
make up
Then you can run all tests by using in another terminal:
make docker-test
If you want to test only monolith version:
make docker-test-monolith
or microservices:
make docker-test-microservices
