frisby

Build Status GoDoc GitHub release

REST API testing framework inspired by frisby-js, written in Go

Proposals

I'm starting to work on frisby again with the following ideas:

  1. Read specification files
  • pyresttest
  • frisby.js
  • swagger spec
  • other?
  1. Use as a load tester
  • like Locust.io
  • distributed
  1. UI
  • Dashboard
  • Analytics
  • Reports
  • Manage multiple instances
  1. Backend
  • master/minions
  • db for analytics
  • api for UI / clients Goa
  • federation of minion groups?

Please comment on any issues or PRs related to these proposals. If you don't see an issue, PR, or idea; definitely add it!

Installation

go get -u github.com/verdverm/frisby

Basic Usage

First create a Frisby object:

// create an object with a given name (used in the report)
F := frisby.Create("Test successful user login").
    Get("https://golang.org")

Add any pre-flight data

F.SetHeader("Content-Type": "application/json").
	SetHeader("Accept", "application/json, text/plain, */*").
	SetJson([]string{"item1", "item2", "item3"})

There is also a Global object for setting repeated Pre-flight options.

frisby.Global.BasicAuth("username", "password").
	SetHeader("Authorization", "Bearer " + TOKEN)

Next send the request:

F.Send()

Then assert and inspect the response:

F.ExpectStatus(200).
    ExpectJson("nested.path.to.value", "sometext").
    ExpectJson("nested.path.to.object", golangObject).
    ExpectJson("nested.array.7.id", 23).
    ExpectJsonLength("nested.array", 8).
    AfterJson(func(F *frisby.Frisby, json *simplejson.Json, err error) {
		val, _ := json.Get("proxy").String()
		frisby.Global.SetProxy(val)
	})

Finally, print out a report of the tests

frisby.Global.PrintReport()

Check any error(s), however the global report prints any that occured as well

err := F.Error()

errs := F.Errors()
for _,e := range errs {
	fmt.Println("Error: ", e)
}

HTTP Method functions

Your basic HTTP verbs:

  • Get(url string)
  • Post(url string)
  • Put(url string)
  • Patch(url string)
  • Delete(url string)
  • Head(url string)
  • Options(url string)

Pre-flight functions

Functions called before Send()

You can also set theses on the frisby.Global object for persisting state over multiple requests.

( Most of these come from github.com/mozillazg/request)

  • BasicAuth(username,password string)
  • Proxy(url string)
  • SetHeader(key,value string)
  • SetHeaders(map[string]string)
  • SetCookies(key,value string)
  • SetCookiess(map[string]string)
  • SetDate(key,value string)
  • SetDates(map[string]string)
  • SetParam(key,value string)
  • SetParams(map[string]string)
  • SetJson(interface{})
  • SetFile(filename string)

Post-flight functions

Functions called after Send()

  • ExpectStatus(code int)
  • ExpectHeader(key, value string)
  • ExpectContent(content string)
  • ExpectJson(path string, value interface{})
  • ExpectJsonLength(path string, length int)
  • ExpectJsonType(path string, value_type reflect.Kind)
  • AfterContent( func(Frisby,[]byte,error) )
  • AfterText( func(Frisby,string,error) )
  • AfterJson( func(Frisby,simplejson.Json,error) )
  • PauseTest(t time.Duration)
  • PrintBody()
  • PrintReport()
  • PrintGoTestReport()

More examples

You can find a longer example here

package main

import (
	"fmt"
	"reflect"

	"github.com/bitly/go-simplejson"
	"github.com/verdverm/frisby"
)

func main() {
	fmt.Println("Frisby!\n")

	frisby.Create("Test GET Go homepage").
		Get("http://golang.org").
		Send().
		ExpectStatus(200).
		ExpectContent("The Go Programming Language")

	frisby.Create("Test GET Go homepage (which fails)").
		Get("http://golang.org").
		Send().
		ExpectStatus(400).
		ExpectContent("A string which won't be found")

	frisby.Create("Test POST").
		Post("http://httpbin.org/post").
		SetData("test_key", "test_value").
		Send().
		ExpectStatus(200)

	frisby.Create("Test ExpectJsonType").
		Post("http://httpbin.org/post").
		Send().
		ExpectStatus(200).
		ExpectJsonType("url", reflect.String)

	frisby.Create("Test ExpectJson").
		Post("http://httpbin.org/post").
		Send().
		ExpectStatus(200).
		ExpectJson("url", "http://httpbin.org/post").
		ExpectJson("headers.Accept", "*/*")

	frisby.Create("Test ExpectJsonLength (which fails)").
		Post("http://httpbin.org/post").
		SetJson([]string{"item1", "item2", "item3"}).
		Send().
		ExpectStatus(200).
		ExpectJsonLength("json", 4)

	frisby.Create("Test AfterJson").
		Post("http://httpbin.org/post").
		Send().
		ExpectStatus(200).
		AfterJson(func(F *frisby.Frisby, json *simplejson.Json, err error) {
		val, _ := json.Get("url").String()
		frisby.Global.SetProxy(val)
	})

	frisby.Global.PrintReport()
}

Sample Output
