This page, show's the main problem of testing session with rspec and sinatra.

The main problem is that the variable session is not accessible from the test code. To solve it, it suggests (and I confirm) to add the fowling lines at spec/spec_helper.rb:

def session
  last_request.env['rack.session']
end

It will make accessible a mocked session object from the last request at the test code.

Here's my controller code that read's a code param and stores its value at session:

post '/step2callback' do
  session['code'] = params['code']
end

Then here's test code:

context "making an authentication" do
  before do
    post "/step2callback", code: "code_sample"
  end
  it "reads the param code and saves it at session" do
    expect(session['code']).to eq("code_sample")
  end  
end

Same like all other pages.

You need to clarify your question. What is problem with testing session. If problems is that user need to be logged in, then you can use something like this in spec file:

before :each do
  post "/login", {:username => "myuser", :password => "mypass"}
end

which will log you in before each test.

I was only able to get it to work by disabling sessions for the test environment. This blog post has a good example: http://benprew.posterous.com/testing-sessions-with-sinatra
