This is a simple example of how to use mockery with go generate. It is my preferred way of generating mocks, because the mocks configuration is co-located with the interface definition.

1. Install mockery

go install github.com/vektra/mockery/v2@2.23.4 # use latest version

2. Add a go:generate comment to your interface

//go:generate mockery -name=MyInterface -output=mocks -outpkg=mocks -case=underscore
type MyInterface interface {
    DoSomething()
}
 

3. Run go generate

go generate ./...

Example of using xrun(https://github.com/gojekfarm/xrun) to manage multiple components in a Go service.

Components can implement the xrun.Component interface or can be wrapped with xrun.ComponentFunc to be used with xrun.

# kafka consumer
consumer := newKafkaConsumer()
 
# gRPC server
server := newGRPCServer()
 
# metrics server
metrics := newMetricsServer()
 
err := xrun.All(
    xrun.NoTimeout,
    consumer,
    server,
    metrics,
)
