Go Scaffold

A simple project with 3 microservices all running in the same process for easy debugging (using protobuf as interface but without using gRPC as a transport layer).

HTTP requests are sent to PublicApi then forwarded for execution by VirtualMachine which relies on StateStorage to read/write state. This process involves a single node only.

The project is thoroughly tested with unit tests (100% coverage), component tests per microservice (defining its spec), E2E tests (defining the full system spec) and E2E stress tests (running the system under load).

Prerequisites

• Make sure Go is installed (version 1.10 or later).

  Verify with go version

• Make sure Go workspace bin is in your path.

  Install with export PATH=$PATH:`go env GOPATH`/bin

  Verify with echo $PATH

• Make sure Git is installed (version 2 or later).

  Verify with git --version

Prerequisites for tests

• Make sure Ginkgo is installed.

  Install with go get github.com/onsi/ginkgo/ginkgo

  Verify with ginkgo version

Build

• Clone the repo to your Go workspace:

cd `go env GOPATH`
go get github.com/orbs-network/go-scaffold
cd src/github.com/orbs-network/go-scaffold
git checkout master

• Install dependencies with go get -t ./...

• Build with go install

Run

• To run the pre-built binary (should be in path):

go-scaffold

• To rebuild from source and run (this will take you to project root):

cd `go env GOPATH`
cd src/github.com/orbs-network/go-scaffold
go run *.go

Test

• Run all tests from project root with ginkgo ./...

• Run everything except stress with ginkgo --skip=Stress ./...

• Another alternative runner with minimal UI and result caching:

  • Run all tests with go test ./...

    Note: E2E is flaky here for some reason

  • Run everything except stress with go test -short ./...

• Check unit test coverage with:

  go test -cover `go list ./... | grep -v /stress | grep -v /spec | grep -v /types/`
  

E2E Spec

End to end tests (server only) checking compliance to spec

• Run the suite from project root with ginkgo -v ./e2e/spec/

E2E Stress

End to end tests (server only) under extreme random load

• Run the suite from project root with ginkgo -v ./e2e/stress/

Service Spec

Component test checking a single service compliance to spec

• For StateStorage, run the suite from project root with ginkgo -v ./services/statestorage/spec

• For VirtualMachine, run the suite from project root with ginkgo -v ./services/virtualmachine/spec

• For PublicApi, run the suite from project root with ginkgo -v ./services/publicapi/spec
