Mockery

Mockery is a go library that enables programmers to create mock http servers for the purpose of testing their integrations in isolation. It is particularly good at doing performance testing since one instance can handle a very large number of tps. I have tested a basic mockery handling 100,000 tps without using more than 20% CPU on an 8 core system.

Getting Started

Here is an example mockery.

package mockery_test

import (
	"log"
	"net/http"
	. "github.com/bluesoftdev/mockery/httpmock"
	. "github.com/bluesoftdev/go-http-matchers/extractor"
	. "github.com/bluesoftdev/go-http-matchers/predicate"
)

func main() {
	mockery := Mockery(func() {
		Endpoint("/foo/bar", func() {
			Method("GET", func() {
				Header("Content-Type", "application/json")
				Header("FOO", "BAR")
				RespondWithFile(500, "./error.json")
				FixedDelay("10ms")
			})
		})
		Endpoint("/foo/bar/", func() {
			Method("GET", func() {
				Header("Content-Type", "application/json")
				Header("FOO", "BAR")
				RespondWithFile(200, "./ok.json")
				NormalDelay("10s", "5s", "20s")
			})
		})
		Endpoint("/snafu/", func() {
			Method("GET", func() {
				Header("Content-Type", "application/xml")
				Header("Cache-Control", "no-cache")
				Header("Access-Control-Allow-Origin", "*")
				Switch(ExtractQueryParameter("foo"), func() {
					Case(StringEquals("bar"), func() {
						RespondWithFile(http.StatusOK, "response.xml")
					})
					Default(func() {
						RespondWithFile(http.StatusBadRequest, "error.xml")
					})
				})
			})
			NormalDelay("300ms", "120ms", "5s")
		})
	})

	log.Fatal(http.ListenAndServe(":8080", mockery))
}
