= vizres Enables rendering of the body of an HTTP response from inside a functional test. This makes it easy to diagnose problems when building assert_select statements or just sanity check the output of the test. == Installation Install the gem directly: sudo gem install pelargir-vizres --source=http://gems.github.com Or install the plugin in your Rails project: script/plugin install git://github.com/pelargir/vizres.git Or clone the project: git clone git://github.com/pelargir/vizres.git == Usage Insert the vr method in your functional test immediately after an HTTP request has been sent: def test_new post :new vr assert_select "div[id=header]" end vr attempts to open the response body in the default web browser. If you want to open the raw HTML in the default text editor instead, simply pass the :html symbol to the method: def test_new post :new vr(:html) ... end By default, vr looks for an instance variable named @response and calls the #body method on it. If your page body is stored in a different variable, such as when testing a mailer, you can pass the raw HTML directly to vr and it will do the right thing: def test_mailer mail = Mailer.create_notification vr(mail.body) ... end Note that to use the default web view, your Rails application must be running locally on port 3000. This will ensure that the page renders correctly with the appropriate images and stylesheets. The server doesn't need to be running if you use the HTML-only view. == Compatibility vizres requires OS X. Support for Windows is planned. test/spec and test/unit work fine with vizres. RSpec, however, tests views independently of controllers, so vizres won't work with it. If Subversion is installed and accessible on the command line, the temporary files generated by vizres will automatically be marked and ignored by Subversion on check-in. == Running Unit Tests Use the rake command to run the unit tests for the plugin. The tests require that the Mocha gem be installed locally: sudo gem install mocha == Resources Repository: http://github.com/pelargir/vizres/ Blog: http://matthewbass.com Author: Matthew Bass
