See Mini MiniTest Tutorial by Tim Millwood.
We'll use MiniTest::Spec, which is a functionally complete spec engine, to create a spec for a Hello World! Sinatra application. Firstly we create a folder 'spec' within the application directory. Within this, two files.
ENV['RACK_ENV'] = 'test' require 'minitest/autorun' require 'rack/test' require_relative '../app' include Rack::Test::Methods def app Sinatra::Application end
The above code is to go into the file
spec_helper.rb. It sets up the initial setting for the test. We set the
RACK_ENV environment variable to 'test' then require '
minitest/autorun' for MiniTest, 'rack/test' because we are testing a rack based application and our application, in this case app.rb. The Rack::Test::Methods module is included to add a number of helper methods to allow the testing of rack applications. Finally we define the application as a Sinatra Application.
The next file
app_spec.rb will be our spec.
require_relative 'spec_helper' describe 'Hello World' do it 'should have hello world' do get '/' last_response.must_be :ok? last_response.body.must_include "Hello world!" end endFirstly the
spec_helperfile is required, we then create a describe block to describe the 'Hello World' application. Within this a single behaviour. We run a get method against the root route and check the response is ok, and that the page includes the text 'Hello World!'.
