forest - for testing REST api-s in Go

This package provides a few simple helper types and functions to create functional tests that call a running REST based WebService.

install

go get github.com/emicklei/forest

simple example

package main

import (
    "net/http"
    "testing"

    . "github.com/emicklei/forest"
)

var github = NewClient("https://api.github.com", new(http.Client))

func TestForestProjectExists(t *testing.T) {
    cfg := NewConfig("/repos/emicklei/{repo}", "forest").Header("Accept", "application/json")
    r := github.GET(t, cfg)
    ExpectStatus(t, r, 200)
}

graphql support

	query := forest.NewGraphQLRequest(list_matrices_query, "ListMatrices")
	query, err = query.WithVariablesFromString(`
{
	"repositoryID":"99426e24-..........-6bf9770f1fd5",
	"page":{
		"first":20
	},	
}`)
	// ... handle error
	cfg := forest.NewRequestConfig(...)
	cfg.Content(query, "application/json")
	r := SkillsAPI.POST(t, cfg)
	ExpectStatus(t, r, 200)
