rspec users - Sep 2010 - How to use RSpec 2 with Sinatra 1.0

Hello,

I am trying to use RSpec 2 with a Sinatra 1.0 application, but I have
no idea about whether they are compatible or not. I tried this:

in $SINATRA_APP_ROOT/app.rb:

require ''sinatra''

set :app_file, __FILE__
set :root, File.dirname(__FILE__)
set :config_path, File.join(Sinatra::Application.root,
''config'')

require File.join(Sinatra::Application.config_path,
''config.rb'')

# Workaround to fix an issue between Sinatra 1.0 and ruby 1.9.2
# Skipped when app is not launched directly
enable :run if $0.eql?(__FILE__)

get ''/'' do
  haml :index
end

in $SINATRA_APP_ROOT/spec_helper.rb:

require ''db_web_console''
require ''rack/test''

in $SINATRA_APP_ROOT/sinatra_app/sinatra_app_spec.rb:

require ''spec_helper''

def app
  @app ||= Sinatra::Application
end

describe ''Sinatra App'' do

  include Rack::Test::Methods

  it "says Hello" do
    get ''/''
    last_response.should be_ok
    last_response.body.should == ''Hello!''
  end
end

But trying

rspec spec/

, I get this error:


Failures:
  1) Sinatra App says ciao
     Failure/Error: @app ||= Sinatra::Application
     uninitialized constant
RSpec::Core::ExampleGroup::Nested_1::Sinatra

test/methods.rb:46:in `current_session''
     # ./spec/db_web_console/db_web_console_spec.rb:14:in `block (2
levels) in ''


I tried in other ways, but without success... can someone figure out
what can be the problem?

There is no specific support for Sinatra, but Rack::Test gives you the tools you
need.

In this case, the error message is telling you exactly what the problem is. It
can''t find the constant "Sinatra" that is referenced on line
4 of sinatra_app_spec.rb. Try adding ''require
"sinatra"'' to spec/spec_helper.rb.

HTH,
