the problems

 let!(:error_value) {'invalid_token'}
  let!(:error_description_value) {'bad bad token'}

  subject do
    OAuth2::Client.new('abc', 'def', :site => 'https://api.example.com') do |builder|
      builder.adapter :test do |stub|
        stub.get('/success')      {|env| [200, {'Content-Type' => 'text/awesome'}, 'yay']}
        stub.get('/reflect')      {|env| [200, {}, env[:body]]}
        stub.post('/reflect')     {|env| [200, {}, env[:body]]}
        # skip
      end
    end
  end

then you can use those stub request by bellow:

  describe "#request" do
    it "works with a null response body" do
      expect(subject.request(:get, 'empty_get').body).to eq('')
    end

    it "returns on a successful response" do
      response = subject.request(:get, '/success')
      expect(response.body).to eq('yay')
      expect(response.status).to eq(200)
      expect(response.headers).to eq({'Content-Type' => 'text/awesome'})
    end

    it "posts a body" do
      response = subject.request(:post, '/reflect', :body => 'foo=bar')
      expect(response.body).to eq('foo=bar')
    end

    # skip
  end

follow the upon result, I try

  let(:client) { OpenWeixin::Client.from_hash(:access_token => "ACCESS_TOKEN", :expires_in => 7200) }

  let(:user_info) do
    MultiJson.encode({
      openid: "OPENID",
      nickname: "NICKNAME",
      sex: "1",
      province: "PROVINCE",
      city: "CITY"
    })
  end

  let(:snsapi) do
    OpenWeixin::Interface::Snsapi.new(client) do |builder|
      builder.request :url_encoded
      builder.adapter :test do |stub|
        stub.get('/sns/userinfo') { [200, {}, user_info] }
      end
    end
  end

and then use upon stub request

  context "#userinfo" do
    it "return user info"do
      expect(snsapi.userinfo.body).to eq(user_info)
    end
  end

throw bellow exception

  1) OpenWeixin::Interface::Snsapi#userinfo return user info
     Failure/Error: expect(snsapi.userinfo.body).to eq(user_info)
     Faraday::Adapter::Test::Stubs::NotFound:
       no stubbed request for get /sns/userinfo?access_token=ACCESS_TOKEN&openid=12341432134&scope=snsapi_base

and change to bellow will pass the test

  let(:snsapi_connect) do
    snsapi_connect = Faraday.new do |builder|
      builder.request :url_encoded
      builder.adapter :test do |stub|
        stub.get("/sns/userinfo") { [200, {}, user_info] }
        stub.get("/great") { [200, {}, "hellow"] }
      end
    end
  end
  let(:snsapi) do
    client.snsapi.stub(:userinfo) { snsapi_connect.get("/sns/userinfo") }
    client.snsapi
  end

  it "snsapi_connect can great" do
    expect(snsapi_connect.get("/great").body).to eq("hellow")
  end

  context "#userinfo" do
    it "return user info"do
      expect(snsapi.userinfo.body).to eq(user_info)
    end
  end

and check OAuth2::Client class we found

    # The Faraday connection object
    def connection
      @connection ||= begin
        conn = Faraday.new(site, options[:connection_opts])
        conn.build do |b|
          options[:connection_build].call(b)
        end if options[:connection_build]
        conn
      end
    end

so we can and must define all http stub inside 'client' instance
