much excon
              wow

SoStubVeryTest provides a simpler method for stubbing Excon in your tests, because typing Excon.stub({}, {}) over and over again is like taking the first train to Repetitive Stress Injury town.

Further, it provides an easy way to set up default stubs for your test suite, so that you can clear out the Excon stubs that were stubbed in your individual test setup, but still have useful default ones around (they usually return empty arrays and hashes).

Installation

Add this line to your application's Gemfile:

gem 'so_stub_very_test'

And then execute:

$ bundle

Or install it yourself as:

$ gem install so_stub_very_test

Usage

HTTP Verb Stubs

SoStubVeryTest is a module that you include to provide some handy methods for stubbing Excon requests. Here's a random smattering of examples:

stub_get "/foo", [1,2,3]
# Equivalent: Excon.stub({ path: /\A\/foo\Z/, method: :get }, { body: [1,2,3] })
#                     ^ so stubbed

stub_post "/foo", body: [1,2,3], status: 201
# Equivalent: Excon.stub({ path: /\A\/foo\Z/, method: :post }, { body: [1,2,3], status: 201 })
#                                                         ^ very protocol

You can use blocks for your response body:

stub_get "/foo" do
  {
    body: "no meme here"
  }
end
# Equivalent: Excon.stub({ path: /\A\/foo\Z/, method: :get }, { body: "no meme here" })

SoStubVeryTest will naïvely turn path parameters (any group of non-/ preceded by a colon) into regex thingies:

stub_get "/foo/:bar", [1,2,3]
# Equivalent: Excon.stub({ path: /\A\/foo\/[^\/]+\Z/, method: :get }, { body: [1,2,3] })
#                                          ^ much regular expression

Namespacing

You can namespace things:

namespace "/doges" do
  stub_get [] # no path stubs the namespace's path
  stub_post "/wow", [1,2,3]

  namespace "/very" do
    stub_get "/much", {}
  end
end

# Equivalent:
#   Excon.stub({ path: /\A\/doges\Z/, method: :get }, { body: [] })
#   Excon.stub({ path: /\A\/doges\/wow\Z/, method: :post }, { body: [1,2,3] })
#   Excon.stub({ path: /\A\/doges\/very\/much\Z/, method: :get }, { body: {} })

Default Host Setting Upping

You can set a default host:

SoStubVeryTest.default_host = "doge.example.com"
stub_get "/foo", [1,2,3]
# Equivalent: Excon.stub({ path: /\A\/foo\Z/, method: :get, host: "doge.example.com" }, { body: [1,2,3] })

Extra Host Setting Upping

SoStubVeryTest.register_host :doge, "doge.example.com"

# Use namespaces
doge_namespace "/w00t" do
  stub_get "/cool", [] # the host prefix isn't necessary when in a namespace block
end

# Or don't use namespaces
doge_stub_get "/twinkie", []

# Excon.stub({ path: /\A\/w00t\/cool\Z/, method: :get, host: "doge.example.com"})
# Excon.stub({ path: /\A\/twinkie\Z/, method: :get, host: "doge.example.com"})

Providing Default Stubs

You can provide default stubs that will not be cleared when calling SoStubVeryTest.clear_custom_stubs by creating them in a special defaults block:

# Ensures that unless you manually call `Excon.stubs.clear` or override the stub,
# GETing /woot will always be stubbed with a `[]` response.
SoStubVeryTest.defaults do
  namespace "/woot" do
    stub_get []
  end
end

Clearing the Stubs

You can clear any non-default stubs with this cool method:

SoStubVeryTest.clear_custom_stubs
# congratulations you have defeated the stubs

Testing with SoStubVeryTest

For RSpec

In your spec_helper.rb, you'll probably want something like this:

require "so_stub_very_test"

RSpec.configure do |config|
  config.include SoStubVeryTest

  before :all do
    Excon.defaults[:mock] = true
  end

  after :each do
    SoStubVeryTest.clear_custom_stubs
  end
end

Then you can spend less time writing stubs for your specs:

before do
  stub_get "/doge", "hi from doge"
end

it "gets the doge" do
  # ...
end

For Minitest

I don't really use Minitest much (lol i know i'm using it in this very repo), but you'd probs do this:

require "so_stub_very_test"

class TestDoges < Minitest::Test
  def setup
    Excon.defaults[:mock] = true
  end

  def teardown
    SoStubVeryTest.clear_custom_stubs
  end

  def test_the_doge
    stub_get "/doge", "hi from doge"
    assert_equal "hi from doge", Excon.get("http://www.example.com/doge").body
  end
end
