Goodman

Goodman is a Dredd hook handler implementation in Go. The API may change, please Vendor this library.

About

This package contains a Go Dredd hook handler which provides a bridge between the Dredd API Testing Framework and Go environment to ease implementation of testing hooks provided by Dredd. Write Dredd hooks in Go to glue together API Blueprint with your Go project

Not sure what these Dredd Hooks are? Read the Dredd documentation on them

The following are a few examples of what hooks can be used for:

• loading db fixtures
• cleanup after test step or steps
• handling authentication and sessions
• passing data between transactions (saving state from responses to stash)
• modifying request generated from blueprint
• changing generated expectations
• setting custom expectations
• debugging via logging stuff

Installing

Must use Dredd v1.1.0 or greater

go get github.com/snikch/goodman/cmd/goodman

Usage

1). Create a hook file in hooks.go

package main

import (
  "fmt"

  "github.com/snikch/goodman/hooks"
  trans "github.com/snikch/goodman/transaction"
)

func main() {
      h := hooks.NewHooks()
      server := hooks.NewServer(hooks.NewHooksRunner(h))
      h.Before("/message > GET", func(t *trans.Transaction) {
          fmt.Println("before modification")
      })
      server.Serve()
      defer server.Listener.Close()
})

2). Compile your hooks program

go build -o hooks path/to/hooks.go

3). Run it with dredd

dredd apiary.apib localhost:3000 --language go --hookfiles ./hooks

API

The hooks.Server struct provides the following methods to hook into the following dredd transactions: before, after, before_all, after_all, before_each, after_each, before_validation, and before_each_validation. The before, before_validation and after hooks are identified by transaction name.
