Versatile HTTP mocking made easy in Go.

Heavily inspired by nock. See also its Python port, pook.

Take a look to the examples to get started.

Features

  • Simple, expressive, fluent API.
  • Semantic DSL for easy HTTP mocks definition.
  • Built-in helpers for easy JSON/XML mocking.
  • Supports persistent and volatile mocks.
  • Full regexp capable HTTP request matching.
  • Designed for both testing and runtime scenarios.
  • Match request by method, URL params, headers and bodies.
  • Extensible and pluggable HTTP matching rules.
  • Ability to switch between mock and real networking modes.
  • Ability to filter/map HTTP requests for accurate mock matching.
  • Supports map and filters to handle mocks easily.
  • Wide compatible HTTP interceptor using http.RoundTripper interface.
  • Works with any net/http compatible client, such as gentleman.
  • Network delay simulation (beta).
  • Extensible and hackable API.
  • Dependency free.

Installation

go get -u gopkg.in/h2non/gock.v1

API

See godoc reference for detailed API documentation.

How it mocks

  1. Intercepts any HTTP outgoing request via http.DefaultTransport or custom http.Transport used by any http.Client.
  2. Matches outgoing HTTP requests against a pool of defined HTTP mock expectations in FIFO declaration order.
  3. If at least one mock matches, it will be used in order to compose the mock HTTP response.
  4. If no mock can be matched, it will resolve the request with an error, unless real networking mode is enable, in which case a real HTTP request will be performed.

Tips

Testing

Declare your mocks before you start declaring the concrete test logic:

func TestFoo(t *testing.T) {
  defer gock.Off() // Flush pending mocks after test execution

  gock.New("http://server.com").
    Get("/bar").
    Reply(200).
    JSON(map[string]string{"foo": "bar"})

  // Your test code starts here...
}
Race conditions

If you're running concurrent code, be aware that your mocks are declared first to avoid unexpected race conditions while configuring gock or intercepting custom HTTP clients.

gock is not fully thread-safe, but sensible parts are. Any help making gock more reliable in this sense is highly appreciated.

Define complex mocks first

If you're mocking a bunch of mocks in the same test suite, it's recommended to define the more concrete mocks first, and then the generic ones.

This approach usually avoids matching unexpected generic mocks (e.g: specific header, body payload...) instead of the generic ones that performs less complex matches.

Examples

See examples directory for more featured use cases.

Simple mocking via tests
package test

import (
  "github.com/nbio/st"
  "gopkg.in/h2non/gock.v1"
  "io/ioutil"
  "net/http"
  "testing"
)

func TestSimple(t *testing.T) {
  defer gock.Off()

  gock.New("http://foo.com").
    Get("/bar").
    Reply(200).
    JSON(map[string]string{"foo": "bar"})

  res, err := http.Get("http://foo.com/bar")
  st.Expect(t, err, nil)
  st.Expect(t, res.StatusCode, 200)

  body, _ := ioutil.ReadAll(res.Body)
  st.Expect(t, string(body)[:13], `{"foo":"bar"}`)

  // Verify that we don't have pending mocks
  st.Expect(t, gock.IsDone(), true)
}
Request headers matching
package test

import (
  "github.com/nbio/st"
  "gopkg.in/h2non/gock.v1"

func TestMatchHeaders(t *testing.T) {
  defer gock.Off()

  gock.New("http://foo.com").
    MatchHeader("Authorization", "^foo bar$").
    MatchHeader("API", "1.[0-9]+").
    HeaderPresent("Accept").
    Reply(200).
    BodyString("foo foo")

}
Mocking a custom http.Client and http.RoundTripper
package test

import (
  "github.com/nbio/st"
  "gopkg.in/h2non/gock.v1"
  "io/ioutil"

  body, _ := ioutil.ReadAll(res.Body)
  st.Expect(t, string(body), "foo foo")

  // Verify that we don't have pending mocks
  st.Expect(t, gock.IsDone(), true)
}
Enable real networking
package main

import (
  "fmt"
  "gopkg.in/h2non/gock.v1"
  "io/ioutil"
  "net/http"
)

func main() {
  defer gock.Off()
  defer gock.DisableNetworking()

  gock.EnableNetworking()
  gock.New("http://httpbin.org").
    Get("/get").
    Reply(201).
    SetHeader("Server", "gock")

  res, err := http.Get("http://httpbin.org/get")
  if err != nil {
    fmt.Errorf("Error: %s", err)
  }

  // The response status comes from the mock
  fmt.Printf("Status: %d\n", res.StatusCode)
  // The server header comes from mock as well
  fmt.Printf("Server header: %s\n", res.Header.Get("Server"))
  // Response body is the original
  body, _ := ioutil.ReadAll(res.Body)
  fmt.Printf("Body: %s", string(body))

  // Verify that we don't have pending mocks
  st.Expect(t, gock.IsDone(), true)
}

Hacking it!

You can easily hack gock defining custom matcher functions with own matching rules.
